Director Chris Nolan has written a tribute about Heath Ledger. The two had just finished working together on The Dark Knight, and in the tribute, Chris recalls Heath's passion and dedication to his work.
"One night, as I'm standing on LaSalle Street in Chicago, trying to line up a shot for The Dark Knight, a production assistant skateboards into my line of sight. Silently, I curse the moment that Heath first skated onto our set in full character makeup. I'd fretted about the reaction of Batman fans to a skateboarding Joker, but the actual result was a proliferation of skateboards among the younger crew members. If you'd asked those kids why they had chosen to bring their boards to work, they would have answered honestly that they didn't know. That's real charisma—as invisible and natural as gravity. That's what Heath had.
Heath was bursting with creativity. It was in his every gesture. He once told me that he liked to wait between jobs until he was creatively hungry. Until he needed it again. He brought that attitude to our set every day. There aren't many actors who can make you feel ashamed of how often you complain about doing the best job in the world. Heath was one of them.
Those nights on the streets of Chicago were filled with stunts. These can be boring times for an actor, but Heath was fascinated, eagerly accepting our invitation to ride in the camera car as we chased vehicles through movie traffic—not just for the thrill ride, but to be a part of it. Of everything. He'd brought his laptop along in the car, and we had a high-speed screening of two of his works-in-progress: short films he'd made that were exciting and haunting. Their exuberance made me feel jaded and leaden. I've never felt as old as I did watching Heath explore his talents. That night I made him an offer—knowing he wouldn't take me up on it—that he should feel free to come by the set when he had a night off so he could see what we were up to.
When you get into the edit suite after shooting a movie, you feel a responsibility to an actor who has trusted you, and Heath gave us everything. As we started my cut, I would wonder about each take we chose, each trim we made. I would visualize the screening where we'd have to show him the finished film—sitting three or four rows behind him, watching the movements of his head for clues to what he was thinking about what we'd done with all that he'd given us. Now that screening will never be real. I see him every day in my edit suite. I study his face, his voice. And I miss him terribly."
