The documentary that follows Joaquin Phoenix’s transformation from a 2-time Academy Award nominated actor into a Captain Birdseye lookalike who tries to rap has found a buyer. Magnolia Pictures has acquired the rights to the documentary I’m Still Here, and will release it in the US this coming September.

Phoenix caused many a raised eyebrow by announcing in 2008 his decision to quit acting to pursue a rap career. Ever since the announcement, Phoenix has continued to unleash a barrage of crazy on an unsuspecting public. We have been left stunned at his violent outbursts, dodgy concerts, and of course that Letterman Show appearance, which you can gawk at in astonishment below:

Though many believe that this surely must be a hoax, James Gray, who directed the actor in his last film, Two Lovers isn’t so sure, saying that, ‘I’ve seen him in his house, and he has his own recording studio that he built right there. So if this is a hoax, then it’s the most elaborate thing that I have ever seen.’

The documentary will be directorial debut of The Killer Inside Me star, Casey Affleck, who is incidentally Phoenix’s brother-in-law. So is Phoenix’s descent into weirdness all an elaborate hoax for the sake of an experimental mockumetary? We’re betting on yes – no one can honestly take themselves that seriously while sporting a Brian Blessed beard. Just ask Brian Blessed.
