Elusive street artist Banksy may be both in front of and behind the camera in this 'psuedo-documentary', but his identity remains undivulged. Edited by Banksy from footage filmed by LA-based amateur filmmaker Thierry Guetta, the film follows graffiti artists including Shepard Fairey, Invader and Banksy at work - and also shows how Guetta created the pop-street-art alter-ego known as 'Mr Brainwash' and became an overnight sensation in the LA art world.
