(FILES): This March 5, 2006 file photo shows Australian actor Heath Ledger arriving for the 78th Academy Awards at the Kodak Theater in Hollywood. The Oscars are eight months away and the film hasn't even been released, but Heath Ledger's performance in his last film is already generating talk of a rare posthumous Academy Award. Australian heart-throb Ledger, who died of an accidental drug overdose in New York in January aged 28, appears in cinemas later in July 2008 as comic-book hero Batman's chilling arch-enemy, The Joker, in "The Dark Knight."
