Was Joaquin Phoenix‘s “meltdown” totally bogus? The Oscar-nominated actor may have forgotten to shave, tried to join the hip-hop community and acted nutty on The Late Show with David Letterman all for a purpose — a mockumentary he is starring in directed by his brother-in-law Casey Affleck, which will be headed to a theater near you this fall!

The documentary I’m Still Here: The Lost Year of Joaquin Phoenix, has been picked up for distribution and release by Magnolia films, according to a recent report released by Deadline.com.

“No matter what I thought coming in, I came out feeling this was a pretty amazing piece of work, jaw-dropping but dimensional,” Bowles said.

“It is going to get a lot of attention, but it is not some cheap stunt where they said, ‘Let’s do some wild stuff and film it,’ ” he continued. “It is extreme behavior but really good filmmaking as well. Frankly, some of the behavior is very extreme. But it is in the context of the insanity of being in Joaquin’s life for that period of time. It is a unique piece of work that is going to surprise people in different ways.”
