Will Smith and Jaafar Jackson join forces to solve a prison mystery in their next film, action-thriller Supermax. Jaafar Jackson, whose breakout performance as his late uncle in the blockbuster biopic Michael turned him into an overnight star, has joined the cast of Supermax, the upcoming action thriller from Amazon MGM Studios and Miramax. Jackson joins Smith and Anna Sophia Robb in a film built around an impossible crime. For Jackson, Supermax marks his first major project after Michael became a global phenomenon. Giving Jackson another opportunity to prove his breakout performance in Michael was only the beginning of a rapidly ascending career.
