Yahoo! has posted the trailer for the upcoming film I’m Still Here. The documentary is the directorial debut of Casey Affleck and follows Joaquin Phoenix’s ‘retirement’ from acting and new career in hip hop. I’m not sure what to think of this whole thing. Is it a hoax? Is it something done for publicity? The fact that Affleck and Phoenix are brother-in-laws also adds to my skepticism. It just seems too unreal to be taken seriously. Although from the trailer it looks rather serious and dark. I’m Still Here will be released on September 10, 2010.
