Heath Ledger's finest?

Heath Ledger has been touted as an amazing presence in the upcoming "The Dark Knight." David Germain of the Associated Press, who saw a press screening of the movie Thursday night, has this to say:

"The buzz over Heath Ledger's performance as the Joker in 'The Dark Knight' for the last several months was justified. With his final full film role, Ledger delivers what may be remembered as the finest performance of his career."
