Is Joaquin Phoenix really studying for a movie role?

Very possible just that. He is after all a "method" actor.

Keep in mind that JP is a A list actor. He's been acting since he was eight years old and never made a bad movie. He was great at every part he played. That said, he has also won awards for his album in Walk the Line which is pretty amazing since he never sang or played an instrument before that. He's also produced some pretty keen videos. He's so good he has made millions and he does not have to work at anything anymore. So I ask you...why would he be rapping and hiding his fabulous good looks? He's got something going here and we don't know what it is...but I'd bet he is out to prove a point about something sociological. He's a brilliant guy. I'd bet on Joaquin in a heartbeat. We'll have to just wait and see his documentary being filmed by brother inlaw, Casey Affleck. .They ain't wasting their time for nothing. This rapping stuff is a means to an end.
