The Untouchables (1959 TV series)

The Untouchables is an American crime drama produced by Desilu Productions that ran from 1959 to 1963 on the ABC television network. Based on the memoir of the same name by Eliot Ness and Oscar Fraley, it fictionalizes the experiences of Ness as a Prohibition agent fighting crime in Chicago in the 1930s with the help of a special team of agents handpicked for their courage, moral character and incorruptibility, nicknamed the Untouchables. The book was later made into a celebrated film in 1987 and a second, less-successful TV series in 1993.

A dynamic, hard-hitting action drama and a landmark television crime series, The Untouchables won series star Robert Stack the Emmy Award for Best Actor in a Dramatic Series in 1960.

Series overview
The series originally focused on the efforts of a real-life squad of Prohibition agents employed by the United States Department of Justice and led by Eliot Ness (Stack) who helped bring down the bootleg empire of "Scarface" Al Capone, as described in Ness's bestselling 1957 memoir. This squad was nicknamed "The Untouchables" because of its courage and honesty; squad members could not be bribed or intimidated by the mob. Eliot Ness, though, died suddenly in May 1957, shortly before his memoir and the subsequent TV adaptation were to bring him fame beyond any he experienced in his lifetime.

The pilot for the series, a two-part episode entitled "The Untouchables", originally aired on CBS's Westinghouse Desilu Playhouse on April 20 and 27, 1959. Later retitled "The Scarface Mob", these episodes, which featured Neville Brand as Al Capone, were the only episodes in the series to be more-or-less directly based on Ness's memoir, and ended with the conviction and imprisonment of Capone. CBS, which had broadcast most of Desilu's television output since 1951 beginning with I Love Lucy, was offered the new series following the success of the pilot film. Chairman William S. Paley rejected it on the advice of network vice president Hubbell Robinson. ABC, however, agreed to air the series, and The Untouchables premiered on October 15, 1959. In the pilot movie, the mobsters generally spoke with unrealistic pseudo-Italian accents, but this idiosyncratic pronunciation was dropped when the series debuted.

The weekly series first dramatized a power struggle to establish a new boss in the absence of Capone himself (for the purpose of the TV series, the new mob boss was Frank Nitti, although this was, as usual for the series, contrary to fact). As the series continued, a highly fictionalized portrayal of Ness and his crew developed as all-purpose, multiagency crime fighters who went up against an array of 1930s-era gangsters and villains, including Ma Barker, Dutch Schultz, Bugs Moran, Vincent "Mad Dog" Coll, Legs Diamond, Lucky Luciano, and in one episode, Nazi agents. On many occasions during the series' run, Ness would blatantly violate suspects' Fourth Amendment rights with no legal ramifications or consequences.

The terse narration by gossip columnist Walter Winchell, in his distinctive New York accent, was a stylistic hallmark of the series, along with its ominous theme music by Nelson Riddle and its shadowy black-and-white photography, which was influenced by film noir.

Controversy
The show drew harsh criticism from some Italian Americans, including Frank Sinatra, who felt it promoted negative stereotypes of them as mobsters and gangsters. The Capone family unsuccessfully sued CBS, Desilu Productions, and Westinghouse Electric Corporation for their depiction of the Capone family. In the first episode of the first season, the character of "Agent (Rico) Rossi", a person of Italian extraction who had witnessed a gangland murder, was added to Ness's team.

On March 9, 1961, Anthony Anastasio, chief of the Brooklyn waterfront and its International Longshoremen's Association, marched in line with a picket group who identified themselves as "The Federation of Italian-American Democratic Organizations". In protest formation outside the ABC New York headquarters, they had come together to urge the public boycott of Liggett & Myers Tobacco Company (L&M) products, including Chesterfield cigarettes, the lead sponsor of The Untouchables. They expressed displeasure with the program, which to them vilified Italian Americans, stereotyping them as the singular criminal element. The boycott and the attendant firestorm of publicity had the effect Anastasio and his confederates wanted. Four days after the picket of ABC, L&M, denying it had bowed to intimidation, announced it would drop its sponsorship of The Untouchables, maintaining the decision was based on network scheduling conflicts. The following week, the head of Desilu, Desi Arnaz (who had attended high school with Capone's son Albert), in concert with ABC and the "Italian-American League to Combat Defamation", issued a formal three-point manifesto:

 * No more fictional hoodlums with Italian names will be in future productions.
 * More stress will be given to the law-enforcement role of "Rico Rossi", Ness's right-hand man on the show.
 * An emphasis will be given to the "formidable influence" of Italian-American officials in reducing crime with an emphasis on the "great contributions" made to American culture by Americans of Italian descent.

The series also incurred the displeasure of the powerful director of the Federal Bureau of Investigation, J. Edgar Hoover, when the fictionalized scripts depicted Ness and his Treasury agents involved in operations that were actually the province of the FBI. (The Untouchables belonged to the Federal Agency that later became known as the ATF). The second episode of the series, for example, depicted Ness and his crew involved in the capture of the Ma Barker gang, an incident in which the real-life Ness played no part. The producers agreed to insert a spoken disclaimer on future broadcasts of the episode stating that the FBI had primary responsibility for the Barker case.

The Untouchables was an unusually violent TV program for the era and its frequent and surprisingly explicit depictions of drug abuse and prostitution were described by the National Association for Better Radio and Television as "not fit for the television screen". Several episodes included depictions of violence toward children.

In an article titled "The New Enemies of The Untouchables" Ayn Rand argued that the persistent, superficial attacks received by The Untouchables were due to its appeal and its virtues: Its moral conflict and moral purpose.

Episodes and cast
The series had 118 episodes which ran 50 minutes each. Though the book chronicled the experiences of Ness and his cohorts against Capone, and in reality the Untouchables disbanded soon after Capone's conviction, the series continued after the pilot and book ended, depicting the fictitious further exploits of the Untouchables against many, often real-life, criminals over a span from 1929 to 1935. The television episodes were broadcast in no chronological timeline, but were set mostly in the early 1930s (for example, one episode, "You Can't Pick the Number", begins with Winchell's words, "October 1932: the depth of the Depression"), and another episode "Canada Run" begins at Chicago Stadium at the NFL Playoff Game on December 18, 1932. A few episodes were set primarily in a locale other than Chicago (such as the one dealing with the shootout involving Ma Barker and her gang.) Characters and "facts" in the majority of the episodes were more often than not entirely fictitious or loosely based composites of true-life criminals of that era. The gripping theme music was by Nelson Riddle.

Quinn Martin produced the show's first season, which contained elements that could be found in future TV series produced by Martin.

The most prominent Untouchables were portrayed by:
 * Robert Stack as Agent Eliot Ness
 * Nicholas Georgiade as Agent Enrico "Rico" Rossi
 * Paul Picerni as Agent Lee Hobson, (second season on)
 * Abel Fernandez as Agent William Youngfellow
 * Steve London as Agent Jack Rossman (portrayed in the pilot by Paul Dubov)

Other Untouchables members who were prominent at first, but did not last past the pilot or the first season, were portrayed by:

 * Jerry Paris as Agent Martin Flaherty, (first season only-portrayed in the pilot by Bill Williams)
 * Chuck Hicks as Agent LaMarr Kane (first season only-portrayed in the pilot by Peter Leeds) killed off in the first season episode, "The Tri-State Gang."
 * Anthony George as Agent Cam Allison, (first season only) killed off in the season-one finale, "The Frank Nitti Story"
 * Keenan Wynn as Agent Joe Fuselli (pilot episode only)
 * Eddie Firestone as Agent Eric Hansen (pilot episode only)
 * Robert Osterloh as Agent Tom Kopka (pilot episode only)

In addition to the Untouchables themselves, several allies were in more than one episode:
 * Frank Wilcox as Federal District Attorney Beecher Asbury
 * Robert Bice as Police Capt. Johnson
 * Jason Wingreen as Police Capt. Dorset
 * Raymond Bailey as US Attorney for New York John Carvell
 * Barbara Nichols as Brandy La France, showgirl and wife/widow of an informant, appearing in both the pilot and premiere
 * Dane Clark as Dr. Victor Garr
 * John Gabriel as Dr. Daniel Gilford
 * Barbara Stanwyck as Lt. Agatha Stewart, head of the Missing Persons Bureau
 * Ed Asner as Frank, one of Agatha Stewart's assistants
 * Virginia Capers as June, one of Agatha Stewart's assistants

The show also had several recurrent gangsters, many of them loosely based on real-life gangsters of the time:

 * Frank Nitti, Capone's enforcer who takes over the Chicago mob after Capone is imprisoned, portrayed by Bruce Gordon, and appearing in far more episodes than any other gangster
 * Joe Kulak, portrayed by Oscar Beregi
 * Dutch Schultz, portrayed in different episodes by Lawrence Dobkin, Robert J. Wilke, and Warren J. Kemmerling
 * Jake "Greasy Thumb" Guzik, portrayed in the pilot by Bern Hoffman, and in the series by Nehemiah Persoff
 * George "Bugs" Moran, portrayed in different episodes by Lloyd Nolan, Robert J. Wilke, and Harry Morgan
 * Louis Lepke Buchalter, portrayed in different episodes by Gene Roth, Robert Carricart, and Joseph Ruskin
 * Lucky Luciano, portrayed by Robert Carricart
 * Pete Konitz, portrayed by Carl Milletaire
 * Frankie Resko, portrayed by Grant Richards
 * Al Capone, portrayed by Neville Brand, and appearing only in the 2 hour pilot and a 2 part episode
 * Louis Campagna, portrayed by Frank de Kova
 * Augie Viale, portrayed by John Beradino
 * Little Charlie Sebastino, portrayed by Henry Silva
 * Louis Latito, portrayed by Joe De Santis
 * Archie Devlin, Capone's attorney, portrayed by George N. Neise
 * Lucky Quinn, portrayed by John Kellogg
 * Joe Aiello portrayed in two episodes (where he's killed off in both episodes) by H. M. Wynant and Grant Richards
 * Phil D'Andrea, portrayed by Wally Cassell, and appearing only in the pilot and premiere
 * "Fur" Sammons, portrayed by Richard Benedict, and appearing only in the pilot and premiere
 * Tony "Mops" Volpe, portrayed by Herman Rudin, and appearing only in the pilot and premiere

Finally, heard in every episode, but never shown onscreen:

 * Announcer: Les Lampson
 * Narrator: Walter Winchell

Paul Picerni and Nicholas Georgiade were cast as gangsters in Capone and Nitti's mob in the 1959 pilot before being cast in the series.

* Steve London's character of Untouchable Jack Rossman (played in the "Scarface Mob" pilot by Paul Dubov) was in the series since the original season-one series episode, "The Empty Chair", not from season two on as is commonly reported.

** The character of Untouchable William Youngfellow, portrayed by Abel Fernandez, has been mistakenly referred to by Saturday Night Live actor Dan Aykroyd as "Youngblood". This name is incorrect.

Broadcast history
The Untouchables originally aired as a segment of the anthology series Desilu Playhouse in 1959. It was picked up as a regular series by ABC for the 1959 season and was aired on Thursdays from 9:30 to 10:30pm from 1959 to 1962, switching to Tuesday evenings from 9:30 to 10:30pm for its final season (1962–63).

Desilu Productions president Desi Arnaz had originally offered the role of Ness to Van Johnson. Johnson's wife and manager rejected the deal and demanded double the salary offer. Arnaz refused and signed Stack instead. Arnaz had had a long business relationship with CBS, which had aired many Desilu programs, including I Love Lucy and The Lucy-Desi Comedy Hour. When CBS refused to buy the program, Arnaz sold it to ABC.

Neville Brand reprised his role as Al Capone in the 1961 film The George Raft Story.

Some segments were released to theaters as movies: The Scarface Mob (from the two-part pilot), The Alcatraz Express (from "The Big Train"), and The Gun of Zangara (from "Unhired Assassin").

On November 10, 1991, NBC ran the two-hour film The Return of Eliot Ness, with Robert Stack as Ness. It was set in 1947, after Capone's death, and depicted Ness investigating the death of an Untouchables agent named Labine.

Legacy
The Untouchables was a landmark television series that has spawned numerous imitators over the decades, such as S.W.A.T., The F.B.I., Crime Story, the original Hawaii Five-O (Five-O's creator and executive producer, Leonard Freeman, served as executive producer on The Untouchables' final season), Robert Stack's two later series, Strike Force and Most Wanted, The Hat Squad, and the 1993 The Untouchables syndicated TV series.

It also inspired films such as Al Capone starring Rod Steiger, The Untouchables (with Kevin Costner), Gangster Squad, Mulholland Falls, and others. The Untouchables is one of two series from 1959, the other being The Detectives, together credited with the concept of depicting a group of crime fighters. Previously, most TV crime dramas had followed one of two formats: either a duo composed of a stalwart police officer or detective and his trusty sidekick/partner (Dragnet, The Lineup), or a lone-wolf private eye or police detective (Peter Gunn, Richard Diamond, M-Squad).

Assessments of cultural impact
In their 1988 book, The Critics' Choice—The Best of Crime and Detective TV, authors Max Allan Collins and John Javna chose The Untouchables as one of the "Top 10 Best Police TV Series (Police Procedurals) of All Time".

The Lebanon (Pa.) Daily News said of The Untouchables: "Between the hard-nosed approach, sharp dialogue, and a commendably crisp pace (something rare in dramatic TV at the time), this series is one of the few that remains fresh and vibrant. Only the monochrome presentation betrays its age. The Untouchables is one of the few Golden Age TV shows that deserves being called a classic."

In 2019, a 60th Anniversary Retrospective titled The Untouchables Retrospective was undertaken to celebrate the show's cultural impact and legacy in television and film history through mixed media, including extensive episode reviews, a podcast, and a making-of documentary. To date, the retrospective has interviewed several surviving participants involved with the program, including Pat Crowley and Nehemiah Persoff.

In popular culture
In Billy Wilder's Academy Award-winning 1960 movie The Apartment, a corporate telephone operator being romanced by an executive objects to the rescheduling of a tryst as it will conflict with the broadcasting of The Untouchables.

Warner Bros. Cartoons spoofed the Untouchables series in the 1963 Merrie Melodies cartoon short The Unmentionables, with Bugs Bunny playing the role of Elegant Mess, a crime fighter assigned to infiltrate a black market ring operated by Rocky and Mugsy.

The series was also spoofed on an episode of the 1961-62 ABC-TV/Hanna-Barbera cartoon series Top Cat entitled "The Unscratchables".

In a 1963 on another ABC-TV/Hanna-Barbera cartoon, The Jetsons, in an episode where Elroy Jetson runs away from home,a group of mobsters was conning both Elroy and his dog "Astro" they are producing a TV show called "The Unspaceables" to cover up a robbery they committed in front of Elroy and Astro.

NBC's Saturday Night Live spoofed The Untouchables several times during the 1970s, with Dan Aykroyd playing Eliot Ness. Incidentally, Aykroyd would parody another popular TV police procedural from the era, Dragnet, in 1987, which co-starred Tom Hanks.

On a 1981 telecast of NBC-TV's The Tonight Show, The Untouchables was spoofed with a skit entitled: "The Video Untouchables", with host Johnny Carson portraying Agent "Eliot Nielsen", whose squad apprehended citizens who unlawfully videotaped TV programs. The video survives today on YouTube.

Episodes
In 1997, the episode "The Rusty Heller Story" was ranked number 99 on TV Guide's 100 Greatest Episodes of All Time.

Region 1
CBS DVD (distributed by Paramount Home Entertainment) have released all four seasons of The Untouchables on DVD in region 1, all digitally remastered from the original negatives and presented uncut, unedited and in its original broadcast order. The first two seasons have also been released in region 4.

On May 10, 2016, CBS DVD released The Untouchables- The Complete Series on DVD in Region 1.

Region 2
Paramount Home Entertainment released the first three seasons of The Untouchables on DVD in the UK. These releases are full-season sets as opposed to Region 1 and 4, where each season has been split into two volumes. The complete series (all 4 seasons) was released on DVD in the UK on May 29, 2017 by Medium Rare Entertainment.

Merchandising
The TV show was also adapted into a comic book by Dan Spiegle, distributed by Dell Comics.

For x86, this means that near jumps, calls and conditional jumps (but not short jumps and conditional jumps) are converted from the machine language "jump 1655 bytes backwards" style notation to normalized "jump to address 5554" style notation.

That "and conditional jumps (but not short jumps and conditional jumps)" doesn't seem to make much sense. If someone knows what it's supposed to say, please correct. Otus (talk) 14:05, 27 August 2009 (UTC)

Solid compression
Okay, what the heck is Solid compressing? I'm going to take it out of the main page just now, and we can put it back when I have some idea what it is. There's probably a better english-language phrase already in use. -- Finlay McWalter 23:41, 10 Nov 2003 (UTC)
 * A FAQ of solid archives: http://pot-pourri.fltr.ucl.ac.be/files/ARCH/RAR_FAQ.TXT whkoh 03:59, Dec 1, 2003 (UTC)

I made and linked to a new page on solid compression. The term is also used in reference to the RAR format, so it's best to have it in one place. Graue 23:49, 14 May 2005 (UTC)

Branch targets
The article mentions: "Compressors which encode branch targets to improve ..."

What is a branch target?

This refers to machine instructions. A particular type of instruction tells the CPU to 'branch' or 'jump' to another address based upon some condition. The specified address ('target') can be absolute or relative (to the address of the current instruction). The terminology "branch" here most likely also includes unconditional jump instructions.

How does this impact compression? Well, for example, if there are 20 branch instructions branching to the same address and the address specification is absolute, this repeated pattern can be easily compressed. However, if the address specification is relative, no pattern is obvious. I suspect that 'encoding branch target [addresses]' transforms the data stream so that relative addresses form patterns. -- Rick Jones Aug 07, 2005.

Documentation
Is 7z format documented anywhere? The 7-zip web site has a page of general info about the format (i.e. a brief list of supported features) but I mean an actual specification that an implementer could use. Thanks. Phr (talk) 23:36, 19 July 2006 (UTC)

 * Check the source code file, subdirectory DOC/. Simosx 21:24, 29 July 2007 (UTC)

 * I've just started describing the 7z file specification as a part of OSS alternative library development project, with knowledge from implementation experiences and standardization project experience as an editor. It may help to clarify the 7z format for other implementer. https://py7zr.readthedocs.io/en/latest/7zFormat.html If any 3rd party become refer it, it will be able to be cited into the article.

Changing Encryption to Security
I think it would be good to change the section Encryption to Security. Security is a superset of Encryption, and we can add issues such as the option to encrypt filenames. Simosx 00:40, 30 July 2007 (UTC)

LZMA error
This page states that the LZMA compression algorithm has a variable compression-dictionary size that can go up tp 1GB, both the 7zip site and the LZMA Wikipedia page say it can go up to 4GB —Preceding unsigned comment added by AlucardNoir (talk • contribs) 10:56, 29 June 2008 (UTC)

Unclear Wording
The page says that LZMA2 provides "better compression ratio for data than can't be compressed". That doesn't make sense. —Preceding unsigned comment added by Brantgurga (talk • contribs) 16:00, 2 November 2009 (UTC)
 * It does make sense, it's just you who don't understand it. It just means that LZMA2 has less overhead when producing compressed output out data which cannot be compressed. Artem-S-Tashkinov (talk) 08:26, 20 December 2009 (UTC)
 * I agree it is confusing as written. There is a tiny amount of overhead for metadata in any file compression algorithm (for storing filenames, checksums, attribute bits, etc.)  But because the claim has no citation for someone to find out what it really means, a person trying to learn something new (probably a good reason for Wikipedia to exist) is left scratching their heads at an apparent self-contradiction.  I will try to find a reliable source to back this claim up, and if I find one, I will cite that reference and improve the wording.  Failing that, I would be inclined to delete the entire sentence because in its current state it harms the article more than it helps.  The claim might not even be true, for all I know.  CosineKitty (talk) 16:15, 21 December 2009 (UTC)
 * I found an explanation in the LZMA source code and cited it. I revised the wording in a way I hope is less confusing: the source implies that when incompressible data is encountered, most compression algorithms will generate output that is bigger than the input.  LZMA2 apparently causes less expansion than LZMA.  CosineKitty (talk) 15:57, 3 January 2010 (UTC)

LZMA2 decompression speed
I added that LZMA2 has ... "much faster than LZMA decompression speed." according to my own research and it was subsequently removed requiring "Citation needed". I decided no to take any action further since I have yet to find any reliable Internet sources which can be accepted as a citation. Artem-S-Tashkinov (talk) 08:32, 20 December 2009 (UTC)

 * LZMA2 does not decompress faster. See http://compressionratings.com/comp.cgi?7-Zip+9.01a+-mx%20-md48m+7-Zip+9.01a0+-m0%3Dlzma2%20-mx%20-md48m LZMA2 announcement listed 2 simple modifications: work is divided into blocks that are compressed separately for faster (but worse compression) multithreading performance and data is further divided into sub-blocks that can be stored (to minimize expansion). So if your data was already compressed it did "decompress faster" since no decompression was needed. Samir000 (talk) 18:52, 20 December 2009 (UTC)

 * Thanks for the link because it partly proved my theory: if you look at results of Image2, Source1, Database1, PGN1 and Pitches1 tests you will notice that LZMA2 decompression speed is from 30 to 60% better. Anyway, these results are quite mixed and they cannot be applied to all existing file types, so let's leave these findings out of this article (besides Igor warned that LZMA2 is an experimental codec and it may be removed or abandoned in the future). Artem-S-Tashkinov (talk) 23:44, 27 December 2009 (UTC)

 * Apparently you are reading it incorrectly. DT = Decompression Time. So the difference is about 0% and the results aren't mixed at all. Samir000 (talk) 20:02, 29 December 2009 (UTC)

MM compression
Why exactly does revision 339711452 fall under WP:FORUM definition/rule? Artem-S-Tashkinov (talk) 13:41, 25 January 2010 (UTC)
 * I'm talking about this edit: The 7z format doesn't contain good filters for multimedia data, thus it doesn't compress well multimedia file formats like BMP, raw WAV audio, raw uncompressed video, etc. This is a recurring request and topic in 7-zip support forums. This problem can be partially resolved by using third-party multimedia preprocessors like MM compression library. Artem-S-Tashkinov (talk) 12:06, 10 February 2010 (UTC)

file permissions
The article says that the 7z format does not store UNIX owner/group permissions, but when I compress/decompress a file with the compress dialog of Nautilus on Debian, the file created from the archive has the executable flag set iff the original file has it set  —Preceding unsigned comment added by 78.48.154.27 (talk) 17:25, 5 February 2010 (UTC)

 * p7zip, aka. Portable 7zip, which port 7zip onto POSIX platforms such as Linux/Mac, support UNIX extension for file property. It allows Linux and Mac 7z commaand to store and retrieve permissions. Debian package is actually p7zip. Miurahr (talk) 02:35, 12 August 2020 (UTC)

 * we can say 'Original 7zip application on Windows does not store filesystem permissions (such as UNIX owner/group permissions or NTFS ACLs), but p7zip store UNIX permissions as a UNIX extension of file property. Even storing permissions, it still does not store user/group name or id, and NTFS ACLs, it can be inappropriate for backup/archival purposes. Even inappropriate for archival, it is used for application packaging, such as Qt package distributions, because installer can handle these properties out of box.'

Differences between 7z and LZMA
Reading over the Lempel–Ziv–Markov chain algorithm article, it appears they have an "official" file format, LZMA2. If that is what it is saying, I'm not clear. Questions:

 * 1) does anyone actually use LZMA2 as a file format? I don't recall having ever seen it in the wild. But I don't see a lot of 7z either.
 * 2) is the LZA compression system used in 7z/7zip identical to that in the "natural" LZMA file? Or is it a separate implementation?

Maury Markowitz (talk) 13:21, 11 October 2015 (UTC)

Encryption mode?
Which encryption mode does 7z use? CBC? GCM? Any kind of authenticated encryption? How does it check whether the user enters the right password? --RokerHRO (talk) 11:38, 28 November 2018 (UTC)
 * 7z use AES256-CBC mode. 7z produce secret key from user provided password, and cycle parameter and IV which are defined in 7z header. To produce a secret key implementation use SHA256 repeatedly. Roughly say, next pseudo code show logic 'for $i in 2^cycle times{ m = sha256.update($password.encode(UTF16-LE) + $IV + $i.as_long_long)}; return m[:32]'.   Implementation just  try to produce secret key and try decrypt data stream using AES256-CBC. Because 7z format has a CRC of unpacked stream, then implementation can know it is as same as recorded CRC or not. If not, the password may be wrong or archive is broken.
