Joaquin Phoenix on Letterman Tom February 12, 2009 Celebs Has this dude lost it? I seriously hope that this is some sort of stunt/act and that Casey Affleck is filming some faux documentary about an actor leaving behind an amazing career to focus on rap… Kinda like This is Spinal Tap. If it’s not an act someone needs to step in before he ends up dead in a River… Phoenix. Do you think this is a joke? I’ve read that he never breaks character no matter where he goes and if it is a joke he’s very committed. Personally I think it’s a joke, but I guess we’ll just have to see. What are you thoughts? Leave a comment and let us know. ps: I’ll embed the video in this post later today.
