Banksy displays his art on public surfaces such as walls and even going as far as to build physical prop pieces. He does not sell photos of street graffiti directly himself. However, art auctioneers have been known to attempt to sell his street art on location and leave the problem of its removal in the hands of the winning bidder. Banksy's first movie, "Exit Through the Gift Shop", billed as "the world's first street art disaster movie," made its debut at the 2010 Sundance Film Festival. The movie was released in the UK on 5 March 2010. In January 2011, he was nominated for the Academy Award for Best Documentary for the movie.
