Heath Ledger's penultimate performance will be as the Joker in The Dark Knight, and by at least one account, the performance should be chilling. Michael Caine told WENN that Ledger so scared him that he forgot his lines.
You think Jack Nicholson in the role and you can't imagine anyone topping him. Heath's just as good in another direction. He's terrifying. The first time I saw him, we were rehearsing. He comes up in the elevator to me in Batman's flat and raids the place. And I hadn't seen him, I'd never met him and he comes out screaming and it's like 'wow'. I completely forgot my lines. Scary. It will frighten the life out of people.
The Dark Knight opens on July 18, 2008, and stars Christian Bale, Heath Ledger, Morgan Freeman, Gary Oldman, Aaron Eckhart and Maggie Gylenhall.
