Dirty Mary, Crazy Larry is a 1974 American road crime drama film based on the 1963 Richard Unekis novel titled The Chase (later retitled Pursuit). Directed by John Hough, the film stars Peter Fonda, Susan George, Adam Roarke, and Vic Morrow. Although Jimmie Haskell is credited with writing the music score, the soundtrack contains no incidental music apart from the theme song "Time (Is Such a Funny Thing)", sung by Marjorie McCoy, over the opening and closing titles, and a small amount of music heard over the radio.
