So, Banksy has made a film. Called Exit Through the Gift Shop, it premiers at the Sundance Film Festival on Sunday – a taster below. Coined as ‘the world’s first street art disaster movie’, it’s narrated by Rhys Ifans and follows the story of a shopkeeper who tries to track down Banksy. Part documentary / part fiction, the film features interviews with famous streetartists, whose work you’re sure to recognise. But though Banksy speaks, he doesn’t reveal his face. What a tease.
