Or mockumentary. But for the sake of Phoenix and director Casey Affleck’s filmmaking intentions, I’ll go on referring to it as a documentary. According to Hollywood News, Magnolia Pictures (American distributor of the likes of Bubble, Jesus Camp, and Let the Right One In) announced today that they’ve picked up rights to the film – now officially titled I’m Still Here, an obvious play on the Dylan bipoic I’m Not There – and will be releasing it in theaters on September 10, 2010. Here’s the official synopsis:

With remarkable access, “I’m Still Here” follows the Oscar-nominee as he announces his retirement from a successful film career in the fall of 2008 and sets off to reinvent himself as a hip hop musician. Sometimes funny, sometimes shocking, and always riveting, the film is a portrait of an artist at a crossroads. Defying expectations, it deftly explores notions of courage and creative reinvention, as well as the ramifications of a life spent in the public eye.

We have seen some of his public appearances – Letterman, the awful rap performance where he fell off the stage, the press junkets – but what it will come down to is the narrative that they craft, how it is all put together, and how much extra filming they did behind the scenes without the general public’s knowledge.

I’m intrigued. Not necessarily excited, but intrigued.
