The trailer for 'I'm Still Here' has arrived. Starring Joaquin Phoenix as an aspiring rapper named Joaquin Phoenix, the documentary (?) has been in the works for over a year, ever since the 'Walk the Line' actor emerged into the spotlight with a gnarly beard and equally unruly hair to make bizarre public appearances, including a now-infamous sit-down with David Letterman.

All the while, Phoenix was tailed by his camera-toting bro-in-law, Casey Affleck, who directed. The trailer itself doesn't really say much about the film, except that there will be plenty of screen time for the beard, in addition to scenes involving a frustrated Phoenix riding on planes, hugging P. Diddy and looking down in the dumps. Watch after the jump!
