Mockumentary

Fans were shocked by Joaquin Phoenix's bizarre demeanor, scruffy look and awkward appearances, but now the world knows it was all a hoax. The actor's behavior last year was chronicled in the supposed documentary I'm Still Here. Hailed as a look into the life of one of Hollywood's leading men, the film was directed by Phoenix's brother-in-law, Casey Affleck.

Now, after months of unexplained strange behavior and the recent TIFF scandal, it's been revealed that I'm Still Here was all for show. "It's the performance of his career," Affleck told the New York Times. "I never intended to trick anybody. The idea of a 'hoax' never entered my mind."

If the idea of a hoax never entered his mind, then why create buzz around a fake film? Both men are famous in their own right and don't need a mockumentary to create buzz for their careers. What do you think their motivation was?
