The Hollywood Reporter reports Danny Glover has joined the cast of Bill Condon's ""Dreamgirls"" for DreamWorks Pictures.

Based on the stage musical, the story is loosely based on the Supremes, but tells of a rising group of singing girls named the Dreamettes.

The trade adds that Beyonce Knowles already has been cast as Deena Jones, one of the Dreamettes, while Jamie Foxx has been cast as Svengali-like manager Curtis Taylor Jr. and Eddie Murphy as R&B star James ""Thunder"" Early."
