!![[Music/{{Chicago}} The band]]:
* SavedFromDevelopmentHell: ''Stone of Sisyphus'' was originally Chicago XXII in 1994. It was eventually released in 2008 as Chicago XXXII, after a label change (the original label was [[ExecutiveMeddling one of the main reasons]] why it wasn't released in '94) and with one track missing.
* ThrowItIn: On a lot of the early albums. Many fans got upset when the false start for "Happy Man" got removed from the Rhino remaster of ''Chicago VII''. Also, listen near the end of "Aire" for a more... humorous example.

!!The original nonmusical play:
* RealitySubtext: The play is VeryLooselyBasedOnATrueStory, adapted from cases the author had reported on. The woman Velma was based on attended the original premiere of the play.

!!The Broadway musical:
* ColbertBump: Of sorts. The 1996 revival was helped by the real-life O.J. Simpson trial, which highlighted celebrity, murder, and getting away with it.
* StuntCasting: The revival has become known for casting well known actors and singers in the three lead roles.

!!The musical film:
* AFIS100Years100Songs:
** #98, "All That Jazz"
* AFISGreatestMovieMusicals: #12
* AwardCategoryFraud: Catherine Zeta-Jones was nominated at the Oscar and BAFTA awards for Best Supporting Actress, even though the role of Velma Kelly in Chicago previously earned Babe Neuworth a Leading Tony.
* AwesomeDearBoy: Catherine Zeta-Jones was originally approached to play Roxie. Zeta-Jones asked "Who gets to sing 'All That Jazz'?" and when they said "Velma Kelly," she ''immediately'' requested to be cast as Velma, even though it was a smaller part, ''just'' so she could sing that song.
* CreatorCameo: Chita Rivera has a couple lines in the scene before Mama Morton arrives.
* CutSong: A few from the stage show, the most notable being Velma's "I Know a Girl", Roxie and Velma's "My Own Best Friend", and Velma and Mama Morton's "Class". The latter was actually recorded for the film and included on the soundtrack album, but cut from the original print for time.
* DyeingForYourArt: An interesting example. Even though the script didn't call for it, Catherine Zeta Jones decided to cut her hair short for the role because she was afraid that her ordinarily long hair might obscure her face during the dancing scenes, making the audience think that she had a double doing her dancing for her. With the bob haircut that she wears in the movie, there's no doubt that it's really her.
* FakeNationality: Katalin Helinski (the Hunyak) is a ''Hungarian'' character with a ''Polish'' surname played by a ''Russian'' actress. She also speaks a line of Russian briefly in the film after saying the rest in Hungarian.
* TheOtherMarty: Charlize Theron was cast as Roxie when Nicholas Hytner was set to direct. After he dropped out, she had to audition again for Rob Marshall - and lost the part to Renee Zellweger.
* RealitySubtext: Renee Zellweger had no singing or dancing training before the movie, mirroring how Roxie is an inexperienced character who has to learn along the way.
* WhatCouldHaveBeen:
** Creator/CatherineZetaJones was originally approached to play Roxie, but wanted to play Velma because of the song "All That Jazz".
** Music/BritneySpears was supposed to play the heiress in this movie. Mandy Moore likewise auditioned but was turned down for being too young.
** Creator/HughJackman was offered the role of Billy Flynn, but he turned it down, as he felt that he was too young for the part. Later, he admitted that he regretted making that decision. John Travolta was repeatedly offered the part but kept turning it down. He too later said he regretted it.
** Film rights were bought back in the 1970s, with Bob Fosse to direct. Goldie Hawn, Liza Minelli and Frank Sinatra were announced as stars. Fosse's sudden death caused the project to be shelved.
