We already miss seeing Joaquin Phoenix on the big screen after he announced his retirement from acting in October, but don't fret, we'll still be able to catch him on screen one more time! Joaquin is filming a documentary that will showcase his transition from acting to music. First stop on his doc tour? Joaquin and his pal Casey Affleck hit a night spot in Culver City for their funk night and Joaquin surprised the audience with a rap performance! We hope at least some of his music is Johnny Cash-inspired!
