Notorious street artist Banksy, whose work has decorated his hometown of Bristol and Israel's West Bank barrier, has turned his hand to film. Exit Through The Gift Shop will have its world premiere at the Sundance Film Festival. Banksy said: "It's the story of how one man set out to film the un-filmable. And failed". The film contains exclusive footage of Banksy, and many of the world's most infamous graffiti artists at work. But until the film is shown, it is not known whether Banksy's identity will be revealed. In the past, the artist has both mythologised and subverted his own image, so the film could raise as many questions as it answers. John Cooper, director of the Sundance Festival, said the story was so bizarre that he questioned whether it could be real. "Exit Through The Gift Shop is one of those films that comes along once in a great while, a warped hybrid of reality and self-induced fiction while at the same time a totally entertaining experience," he added. Exit Through The Gift Shop is due to open in UK cinemas on March 5, 2010. Check it out below!
