"The NWA biopic Straight Outta Compton has run into a serious snag, and Fantastic Four is to blame. Michael B. Jordan, who set haters aflame when he was cast as Johnny "The Human Torch" Storm, was being eyed to play a young Dr. Dre in the drama about the trailblazing rap group. However, Fantastic Four's shooting schedule has made him unavailable. Now producers are scrambling to find a cast to play teen-to-twenty-something versions of Dr. Dre, Ice Cube and the late Eazy-E.
THR reports Jordan was a casting choice favored by Dr. Dre himself. He and Ice Cube are serving as producers on Straight Outta Compton, along with Eazy-E's widow, Tomica Wright. All three of these producers clearly have a vested interest in how NWA is presented in the film, and part of their powers include casting approval. But with Jordan out, there's no clear runner-up."
