Joaquin PhoenixFor those of you still wondering whether Joaquin Phoenix's recent string of odd behavior was completely legit or all part of some grand prank, your questions may soon be answered; 'I'm Still Here,' the new Casey Affleck-directed (mock?)umentary that will reportedly cover all of his antics, hits theaters on Sept. 10.

In the meantime, Magnolia Pictures today released the official poster from the movie, which features Phoenix looking just as he did during his now-infamous appearance on the 'Late Show With David Letterman' -- ie, haggard. (So much for him actually being "here.")

Check out the poster, then relive his 'Late Show' fiasco after the jump.
