A new clip has been released to promote Casey Affleck's I'm Still Here, a pseudo-documentary about Joaquin Phoenix's transition from acting into rap music, and boy is it hilarious. Basically, Joaquin takes a trip to see Sean "P. Diddy" Combs about doing an album together. Needless to say, it doesn't go as he planned.

I'm Still Here opens in theaters this Friday. Check out the new clip below, and see the film's trailer in our I'm Still Here trailers gallery.
