Tilda Swinton @ Oscars 2008

Tilda Swinton (in Lanvin) arrives at the 2008 Oscars held at the Kodak Theatre on Sunday in Hollywood.

Tilda, 47, won Best Actress in a Supporting Role for her role in Michael Clayton. During her acceptance speech, she thanked costar George Clooney.

Swinton addressed Clooney, jokingly saying, “You know, [you have such a] seriousness and dedication to your art. Seeing you climb into that rubber bat suit from Batman & 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. Thank you, thank you, thank you.”
