Joaquin Phoenix had us all the way

Looks like Joaquin Phoenix's plane crash of a career switch to scruffy bearded rapper was in fact more of an Andy Kaufman-like prank. His appearance on Letterman, crazy bootleg rap routine (all of which can be seen via the Mashable article) were all part of a doc/mockumentary directed by Casey Affleck, brother of Ben. At the moment it's unclear if this a comedy or drama. Either way, that's dedication.
