Exit Through the Gift Shop

An enthusiastic and eccentric film maker spends years filming the adventures of US graffiti artists, trying to track down the Holy Grail, Banksy. Following a chance encounter with him, the film maker then gets to follow Banksy around, filming him as he creates his public displays of art.

They get into some nasty scrapes, including one time when Banksy plants a Guantanemo Bay prisoner (complete with orange overalls) in Disneyland. This film is a great insight into the underground art scene, but the second half of the film takes a much different direction, showing just how ludicrous the the art world can be. Definitely worth a watch, even if you're not a big Banksy fan.
