Amateur filmmaker Thierry Guetta's project to chronicle the underground world of street art takes a fascinating twist when he meets Banksy, an elusive British stencil artist, in this Independent Spirit Award winner for Best Documentary. Unimpressed with Guetta's footage, Banksy takes over filmmaking duties while Guetta reinvents himself as a street artist and -- much to Banksy's surprise -- instantly becomes a darling of the Los Angeles art scene.
