Sean Combs is going to be acting again, which is utterly unforgivable.

“Acting is not creativity, it’s doing what somebody else tells you to do,” Joaquin Phoenix declares in I’m Still Here, a film that charts his decision to stop being a thespian, grow a massive beard and rediscover himself as a rap artist. Is he crazy? Contradicting his own soundbyte with the most intriguing performance of his career, the answer is a resounding no. The story Phoenix and brother-in-law Casey Affleck have crafted is not insane, but assured – a fascinating study of self-identity.
