9 Actors Who Went Too Far For Roles
Joaquin Phoenix: "I'm Still Here"
It's still hard to classify "I'm Still Here" as a film. If you believe it was a mockumentary, then Joaquin pushed his actorly dedication to the limit, creating beaded, sunglassed, hip hop alter ego JP, and behaving as him in public from the time he started filming until after the movie came out. The whole world bought his act as an unstable actor/ turned musician.
