The Art World's Borat?

Exit Through the Gift Shop (2010)
Directed by: Banksy
Starring: Banksy, Shephard Fairey, Space Invader, & Thierry Guetta

I have absolutely no idea what to make of this movie. It is billed as some kind of mix of comedy and documentary, but a lot of made me think of Sacha Baron Cohen's movies like Borat and Bruno. Is this movie a fake? Is Mr. Brainwash a creation of Banksy so as to make some kind of a statement? I have absolutely no idea.
The movie tells the tale of Thierry Guetta, a French immigrant to LA who ostensibly stumbles into being the official videographer of the street artist movement. He ends up following around people like Space Invader, Banksy, and Shephard Fairey as he attempts to document their work. From here, the movie is the tale of what happens after Guetta gets his first taste of stardom. Guetta eventually becomes a pseudo artist, a man that does not create any of his own work and does insipid riffs on works by other artists.
I am torn on the veracity of this movie. While the story seems almost too bizarre not to be true, there were some very clear stabs at some notable artists and art patrons- and those make me believe the movie might be some kind of a hoax. The clearest stab of all is the discussion of Damien Hirst- where it is pointed out that he makes millions upon millions of dollars for his work and does not actually create any of it, he has a cadre of 100 people working on his ideas. A similar style is seen by Guetta (later calling himself Mr. Brainwash-- which would be such an apt name for satire it's almost astounding). The movie then pokes fun at Madonna and other such people who have since paid Mr. Brainwash for his derivative art. If this movie is not a hoax, then it's a movie designed specifically to destroy Mr. Brainwash's career. Either way- it's a well-made, interesting, and insightful look at the world of street art.
Did I like the movie? Yes. Do I think it's a hoax? I hope so.
