* AllStarCast: The movie version.
* GenreKiller: According to the Medved Brothers' ''Hollywood Hall of Shame'' book, the movie's box-office performance directly led to the cancellation of several major-studio projects that would have had predominantly black casts. Well into the 1980s, Creator/RichardPryor and Creator/EddieMurphy would be the only black leads that were reliable box-office performers, and that was largely via UncleTomfoolery and SaltAndPepper pairings.
* PlayingAgainstType: Directing variant. Creator/SidneyLumet is the last person you'd expect to direct a musical....and it shows.
* StarDerailingRole: Diana Ross landed the starring role despite several early refusals from the film's crew due to her age at the time of production, forcing several changes to the script to accommodate Ross' older version of Dorothy. All of this, combined with the negative critical reaction of her overall performance ultimately prompted Ross to stick to singing instead of acting.
* UnintentionalPeriodPiece: On top of being a product of a time when Blaxploitation films were popular in the U.S., the film has an unmistakable 1970s feel throughout, from its tone, to the fashions, to the disco and funk-heavy soundtrack, among other things.
* WhatCouldHaveBeen: Stephanie Mills who played Dorothy in the original stage show would've reprised the role for the movie had Diana Ross not appealed directly to the head of Universal to get the part.
