Teaser Trailer for that Joaquin Phoenix Documentary I'M STILL HERE

So here is our first look at that weird Joaquin Phoenix documentary directed by Casey Affleck called I'm Still Here. 

The doc follows retired actor turned bad rapper Joaquin Phoenix, and I have no idea what to expect. It should be interesting to see what exactly Affleck and Phoenix have done with this. Apparently the film features Phoenix "snorting cocaine, ordering call girls, having oral sex with a publicist, treating his assistants abusively and rapping badly." 

Here's a short synopsis that doesn't give much information:

I'm Still Here follows Oscar-nominee Joaquin Phoenix 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.

I can't help be curious as to what this film involves, but will it be worth my time? The movie is set to get a limited release on September 10th. Check out the trailer and let us know what you think!
