Director Terry Gilliam has slammed the promotional campaign for the new Batman movie - insisting movie bosses are using Heath Ledger's tragic death to generate publicity for the movie. The actor died of an accidental overdose of prescription drugs in January shortly after shooting his final film - The Imaginarium Of Dr Parnassus - under the direction of Gilliam. And the moviemaker fears that the producers of Ledger's second to last picture, The Dark Knight, are shamelessly capitalising on rumours that the late star will be awarded a posthumous Oscar for his role as evil villain The Joker. He says, "That's what Warner Brothers are saying, but they'll do anything to publicise their film. That's just what they do and you can't get upset because it's bulls**t. "They're like a great white shark which devours whatever it can."
