Anyone who saw Joaquin Phoenix on Letterman last year knew something strange was up with the actor, but he sold it so well, we weren't entirely sure what.
Casey Affleck confirms that Phoenix was just acting when filming the faux documentary I'm Still Here, which Affleck directed. And what a performance it was.

"It's a terrific performance, it's the performance of his career," Affleck tells The New York Times of Phoenix's partying, impromptu rapping and unkempt look.
"I never intended to trick anybody," adds Affleck, who never thought people would think I'm Still Here was serious. "The idea of a 'hoax' never entered my mind."
Guess Joaquin is just that good an actor.
