POLL: Do You Think Heath Ledger Is Oscar-Bound?
It's a haunting Hollywood story: Five months after his untimely death from an accidental drug overdose, Heath Ledger delivers arguably his best screen performance ever in the box-office blockbuster Batman adventure The Dark Knight.

PEOPLE's review calls him "fearless" as the Joker and notes that his role "helps make The Dark Knight unforgettable." And with a record-breaking $158.3 million take at the box office this weekend, the film – and Ledger's role in it – have become a part of movie history.

Just how powerful was his performance? Said his costar Michael Caine earlier this month: "I think Heath will surely get a posthumous nomination for an Academy Award."
