"Exit Through the Gift Shop is…well, we’re not yet sure exactly what it is. Billed as a ‘pseudo-documentary’ and described by Banksy as 'The story of how one man set out to film the un-filmable. And failed,' the film might show Banksy at work and reveal something about the artist. Then again, it might not."
The film is premiering at the Sundance Film Festival. If you're not familiar with Banksy work, well then...there's nothing to be said, except check out one of his art books.
