It was the moment that UK art's great counterculture enigma was ushered into the world of mainstream glitz and glamour. Banksy - whose stencilled street art have made him a household name - was nominated for an Oscar for his documentary Exit Through the Gift Shop. In truth, Banksy had long since transcended the underground - how many graffiti artists sell work to Brad Pitt and Angelina Jolie? - but nevertheless, there was something tantalising about the thought of the man who keeps his identity a secret attending the world's most ostentatious celebrity get together. In the end, we'll never know how Banksy was planning to handle the spotlight because he didn't win. Would he have taken to the podium in disguise? A statement he released before the ceremony suggests he might have: "I don't agree with the concept of award ceremonies, but I'm prepared to make an exception for the ones I'm nominated for. The last time there was a naked man covered in gold paint in my house, it was me."
