In reply to myth:
I didn't know to what extent Exit Through the Giftshop was 'real'.
The most bizarre thing about it is that a few years
after the film, Mr Brainwash is doing hugely successful shows! Amazing, and confusing. Perhaps those fooled initially believe they can regain some dignity by getting on the bandwagon, pretending they knew all along?
Btw, if you don't know anything about ETTGS or Mr Brainwash, I strongly recommend you put that right. The ultimate in the art of piss-take, beautifully executed.
