Sinister new shots of Heath Ledger as The Joker in the new Batman movie The Dark Knight have been released. Many friends of Heath’s believe that it was playing The Joker that lead to him becoming increasingly anxious and unable to sleep, before he tragically died of an overdose in January. Although Heath was filming The Imaginarium Of Doctor Parnassus when he died, he never got to finish it, so his role in The Dark Knight will be the last he completed – and, ironically, looks set to be the biggest box office success of his short career, when it’s released this summer.
