* TheDanza: Several of the minor characters--Jo Ann Brody as Jo Ann (Augustine's mistress), Rutanya Alda as Rutanya (one of Marlowe's hippie neighbors), Jack Riley as Riley (the piano player).
* GenreKiller: Altman is said to have ''wanted'' this film to be this for the HardboiledDetective kind of FilmNoir. [[SubvertedTrope Didn't happen, though.]]
* PlayingAgainstType:
** Elliott Gould, who specialized in playing neurotic, eccentric New Yorkers, as a HardboiledDetective from LA, was of the NewHollywood era's most celebrated examples of this.
** Henry Gibson, best known at the time for his {{Adorkable}} characters on ''RowanAndMartinsLaughIn'', as the dour, amoral Dr. Verringer.
* ScrewedByTheNetwork: United Artists botched its initial release by promoting it as a straight DetectiveDrama. A few months later they re-released it but the marketing implied that it was a rollicking {{Parody}} of Literature/PhilipMarlowe, when it's really more like a darkly satiric {{Retool}}.
* ThrowItIn: It's a Creator/RobertAltman film, so there's lots of this. Elliott Gould ad-libbed many of Marlowe's quips. The shot of the two amorously-engaged dogs on the street of the Mexican village obviously wasn't planned but was memorable enough to stay in the film.
* WhatCouldHaveBeen: Altman originally wanted Dan Blocker (TV's Hoss Cartwright) whom he originally directed in early episodes of ''Series/{{Bonanza}}'' to play Wade. Tragically Blocker died from a post-surgery complication at the age of 44. The film is dedicated to him.
* During filming of ''Film/{{MASH}}'', Elliot Gould and Donald Sutherland approached Fox executives about removing Creator/RobertAltman from the project, but decided not to go through with it. Gould admitted to Altman that he and Sutherland almost had him removed from the filming, but Donald Sutherland never told Altman about it. Subsequently, Altman never made another movie with Donald Sutherland.
