Here's a great series of promo photos for Christopher Nolan's Dark Knight featuring Heath Ledger as The Joker. I wonder if we'll ever see a villain so insanely crazy again. I'm sure we haven't seen the last of The Joker on the big screen. It will be interesting to see what actor is willing to take it on next, and how the chracter is portrayed, because no one can do it like Ledger did. Who do you think would make a good Joker in any future Batman movies?
