British actress Tilda Swinton looked visibly shocked as it was announced that he had won the Oscar for best supporting actress at the Academy Awards on Sunday night. Watch her acceptance speech in full… Tilda won the award for her role in the film Michael Clayton – and dedicated her statuette to her agent in the US. “I have an American agent who is the spitting image of this,” she joked. “Really, truly. The same shape head and, it has to be said, the buttocks.” She also made fun of her Michael Clayton co-star George Clooney, by referring back to his critically-derided stint as superhero Batman. “Seeing you climb into that rubber batsuit from Batman and Robin, the one with the nipples, every morning under your costume, on the set, off the set, hanging upside-down at lunch… You rock, man.” CLICK here to watch Tilda Swinton’s Oscar acceptance speech
