Dreamgirls is a 2006 American musical drama film written and directed by Bill Condon and jointly produced and released by DreamWorks Pictures and Paramount Pictures. Adapted from the 1981 Broadway musical of the same name, Dreamgirls is a film à clef, a work of fiction taking strong inspiration from the history of the Motown record label and its superstar act, The Supremes. The story follows the history and evolution of American R&B music during the 1960s and 1970s through the eyes of a Detroit girl group known as "The Dreams" and their manipulative record executive.

Musical film is a film genre in which songs by the characters are interwoven into the narrative, sometimes accompanied by dancing. The songs usually advance the plot or develop the film's characters, but in some cases, they serve merely as breaks in the storyline, often as elaborate "production numbers".
