'Dark Knight' stars pledge to vote for Ledger

Heath Ledger's co-stars in The Dark Knight have revealed that he already has three Oscar votes in the bag.

Rumours have been rife that the late actor will secure an Academy Award nomination for his performance as The Joker in the latest instalment in the Batman franchise.

Speaking at the film's premiere on Monday night, Aaron Eckhart (Harvey Dent/Two Face) told Teletext: "I'm a member of the Academy so I can vote for him."

Sir Michael Caine, who plays butler Alfred Pennyworth, added, "So can I", while Maggie Gyllenhaal (Rachel Dawes) said: "I'm a member too - the Oscar can only go to Heath."
