It may seem that Banksy has become a victim of the hype machine that he alludes to in "Exit ThroughtheGiftShop, " but his lack of identity is what gives his notoriety its irony.
It beat the art film ExitThroughtheGiftShop putting to rest any worries the Academy might have had about street artist Banksy (who directed the film) trying to accept his award in a monkey mask.
By the time his new documentary, "Exit ThroughtheGiftShop, " winds its way through a slow release in the United States, Banksy will be more popular than ever -- and still, no one will know who he is.
