Dreamgirls (2007)

Effie White, Deena Jones, and Lorrell Robinson - three friends from Chicago - are a promising singing trio called The Dreamettes. Accompanied by their songwriter CC White, they travel to New York to compete in a talent show at the Apollo Theatre. Although the girls lose this first bid for fame, their talent attracts an ambitious manager by the name of Curtis Taylor, Jr, who uses unscrupulous tactics to move the girls from backup singers of superstar James "Thunder" Early to superstars of their own.
