The long-in-development N.W.A. biopic Straight Out of Compton finally started showing some forward progress with the recent casting of Ice Cube’s son O’Shea Jackson Jr., to play the teenage version of his father, and now two more relative unknowns have joined the movie as Cube’s partners in rhyme. Dr. Dre will be played by Marcus Callendar while the late Eazy E will be played by Jason Mitchell.
