Joaquin Phoenix’s “I’m Still Here” gets a trailer

So, let me see if I understand this correctly. Joaquin Phoenix transformed into Zach Galifianakis for a year, used Zach’s persona from his films in real life, filmed it and is now releasing it as a mockumentary? I’m sold. I only have two questions. Where can I pre-purchase tickets to the 3D showing and does Zach get any royalties?
