The Great Return of Joaquin! Joaquin! Joaquin!

The long-expected documentary that Casey Affleck was working on under the radar (ish), the one chronicling his brother-in-law Joaquin Phoenix’s so-called career leap from acting to rapping, I’m Still Here, is ready to be judged.

Check out the intriguing teaser here.

Looks like we’ll see Phoenix’s infamous beyond-bizarre visit with David Letterman and his “performance” at LIV at the Fontainebleau Miami Beach last year, which I witnessed and earned him the nickname Scraggles from yours truly, among much more, including, reportedly, drugs, excess, and a new brand of oblivion.

I’m Still Here will be released on Sept. 10.
