Question: was the movie dreamgirls based on the supremes

Answer: Yes, Dreamgirls is a 2006 American romantic musical comedy-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 by composer Henry Krieger and lyricist/librettist Tom Eyen, Dreamgirls is a film à clef, a work of fiction taking strong inspiration from the history of the Motown record label and one of its acts, 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, Michigan girl group known as the Dreams and their manipulative record executive.
