MTV News caught up with Chris Rock and Adam Sandler on the red carpet for their current movie, Grown Ups, and asked them about their work as producers on an upcoming biopic of the late Richard Pryor. Marlon Wayans is slated to star as Pryor, and Rock defends that choice in this clip. As for when the movie will get made? That remains up in the air. Director Bill Condon, who also wrote the script for Richard Pryor: Is It Something I Said?, has a full plate already this year and will be directing the fourth Twilight film, Breaking Dawn. So when will we get to see a Pryor biopic?
