Ledger, Williams join Dylan biopic cast

LOS ANGELES, May 24 (UPI) -- "Brokeback Mountain" stars and real-life couple Heath Ledger and Michelle Williams are joining the cast of the Bob Dylan biopic, "I'm Not There."

Ledger is in talks to replace Colin Farrell as one of seven actors portraying the folk icon at different stages in his life, The Hollywood Reporter said Wednesday.

Cate Blanchett, Christian Bale, Julianne Moore and Richard Gere have already signed on for the film, written by Oren Moverman and Todd Haynes, who will be directing when production starts in July in Montreal.

Dylan's business manager, Jeff Rosen, is among the producers of the Killer Films project.
