Los Angeles entertainment reporter Sam Rubin said on his KTLA-TV blog that Ledger's role as The Joker is 'amazing work', eports Daily Telegraph.
He said that Ledger 'gives a blockbuster performance' and 'will absolutely be nominated for an Oscar, and at this point in the year, Ledger is also a hands-down favourite to win it posthumously'.
