I didn't realise this film featured Mr Brainwash. I came across Mr Brainwash via another artist on facebook. I don't really like him. Now I understand why.
The film is fantastic though - it is the art worlds spinal tap. You should go see it. It is hilarious in one way, but highlights the stupid parts and the reality of the world of art in others. That bit is still funny, and very very clever, but kind of not funny at the same time.
