Many people have speculated that this entire bizarre interview is an elaborate hoax. The entire story about Joaquin Phoenix quitting acting and becoming a rapper is possibly a hoax. Phoenix's brother-in-law Casey Affleck has been filming all of Joaquin's appearances, supposedly to make a documentary about the career change. Many speculate that he is actually filming a hilarious documentary about how the media will grab on to any story and run with it. You decide for yourself if this is real or not. It sure is an awesome acting job if that is indeed what it is. Dave was classic as well. Many great Letterman quotes to be found here. Please watch.
