Time has passed, but Joaquin is back in Dave's interview chair. The clean-shaven star tries to apologize and promote the film that used his last Letterman interview as its backbone, but Dave isn't one to forgive, not for free anyway.

Casey Affleck, the director of I'm Still Here, the "documentary" about Joaquin Phoenix's descent into drug-fueled, hip-hop-wannabe madness, says it was all a "performance." Yes, everything—including the famous appearance on David Letterman—was faked for the movie.

This is just plain odd. Here's a clip from Joaquin Phoenix's I'm Still Here, featuring Phoenix visiting Sean "Diddy" Combs to discuss a record project. Friendly introductory chatter quickly turns to contentious, profanity-filled awkwardness as Combs lectures Phoenix about money.
