Casey Affleck has screened his documentary, "I'm Still Here", out of competition at the Venice Film Festival.
The documentary, which follows, Affleck's brother-in-law, actor, Joaquin Phoenix as he carries out his day to day life, was thought to be a kind of Andy Kauffman-esque hoax. Phoenix once an Academy Award-nominated actor has decided to become a rapper.
Affleck claims that those rumors are incorrect.
He said "Elliptically, I would say ... I sincerely don't want to influence people's interpretation," he told reporters. "I can tell you there is no hoax. It makes me think of Candid Camera or something."
He said that he would like to let the audiences make up their own minds about the film.
The film is full of the dark side of Phoenix's life. During the film the ex-actor speaks about the irony of the fact that he is appearing on film just as he is trying to escape the industry. He grumbles that he in facts "hates" acting.
He says "I think everyone at some point in their life hates their jobs and the people they are around."
This is his explanation for changing his life so dramatically; from being nominated for an Oscar for his role as Johnny Cash in "Walk the Line" to having this documentary made about him.
The film includes his drug use, graphic language, the search for online sex, a meeting with a prostitute and other hard core scenes. In one of the more shocking scenes Phoenix attacks a spectator at his own concert.
