The upcoming Richard Pryor biopic just got two MAJOR additions to the cast. According to Deadline , Oprah Winfrey and Eddie Murphy have signed on to join Mike Epps — who’s taking on the role of Richard. The Weinstein Company is ready to greenlight its Richard Pryor biopic, and my, have Harvey Weinstein and Lee Daniels put together a terrific cast. The new additions: Oprah Winfrey will play Pryor’s grandmother, who ran a brothel and raised the iconic comic there; Eddie Murphy will play Pryor’s father, Leroy “Buck Carter” Pryor. Kate Hudson is set to play Pryor’s widow, Jennifer Lee Pryor. And Mike Epps is now locked to play Pryor, a role coveted by a lot of actors. Daniels, who worked with Weinstein and Winfrey on the blockbuster Lee Daniels’ The Butler, will start production in March, after wrapping up the second season of his hit Fox series Empire. This should be incredible.
