Remember when Joaquin Phoenix told us that he'd quit acting to pursue a rap career, and acted kinda weird to David Letterman on the Late Show in early 2009, while sporting a full beard and sunglasses, and looking homeless? It was widely speculated that this was an elaborate Andy Kauffman-like stunt; but now, there's a documentary coming out about it, courtesy of Casey Affleck. It's called I'm Still Here. (We can only hope so, Joaquin.)
Watch the trailer after the jump.
In the trailer, Phoenix is mobbed by paparazzi, and gets ready to take the stage. Joke, or no joke? We'll just have to wait and see.
