Casey Affleck admits I’M STILL THERE is a hoax… Casey Affleck has confirmed that the Joaquin Phoenix documentary I’m Still Here was a hoax. Speaking about the film, which follows Phoenix over the course of a year as he attempts to become a hip hop artist, Affleck explained to the New York Times: “It’s a terrific performance; it’s the performance of his career. I never intended to trick anybody. The idea of a ‘hoax’ never entered my mind.” Affleck, who made his directorial debut with the picture, said that most of the film was not real – including the opening shots of Phoenix apparently swimming with his siblings in Panama, which were actually shot in Hawaii with actors. “There were multiple takes, these are performances,” he continued. “We wanted to create a space. You believe what’s happening is real.” The actor turned director added that Phoenix’s now infamous interview on The Late Show with David Letterman last year was all part of the act. Phoenix is to appear on the chatshow again next week, and Affleck revealed that his long-time friend would not be appearing in character this time.
