The star signed on to play Pryor last year (14) in the new biopic, which will also feature Kate Hudson as the late comedian's wife.

"I'm very scared," he tells late night host James Corden. "It's a humble scared because he was the greatest to ever do it and I'm really, really nervous, but I think I'm going to serve Richard Pryor some justice. I'm gonna bring the real to it and I'm just happy and blessed to have the opportunity."

Taraji P. Henson and Eddie Murphy will also appear in the film as Pryor's parents, and Oprah Winfrey will play the funnyman's grandmother.

Epps has been attached to the lead for a decade - and was announced as the man to play Pryor when the funnyman was still alive and Walter Hill was tapped to direct.
