Late actor Heath Ledger deserves an Academy Award for his performance as The Joker in this year’s Batman sequel, The Dark Knight, Rolling Stone film critic Peter Travers wrote on Thursday.

“I can only speak superlatives of Heath, who is mad-crazy-blazing brilliant as the Joker,” Peter says.

“It’s typical of Heath’s total commitment to films as diverse as Brokeback Mountain and I’m Not There that he does nothing out of vanity or the need to be liked. Heath’s Joker has no grey areas — he’s all rampaging id. He creates a Joker for the ages. If there’s a movement to get him the first posthumous Oscar since Peter Finch won for 1976’s Network, sign me up.”

The end credits of the “Batman Begins” sequel include a farewell note to Heath: “In memory of our friends Heath Ledger & Conway Wickliffe,” reads the tribute included in the credits.
