Does Jack Nicholson appear in the Dark Knight?

He says:

I'm not inclined to watch it (The Dark Knight) because of what I said. But if it's a good movie, I'll catch up with it somewhere. I don't think they ever really captured Tim Burton's spirit [since he stopped being involved]. They kind of drove the franchise into the ground. Tim Burton's a genius. He had the right take on it. That's why I did the movie. I did the movie based on a single conversation with him. We both come from the cartoon world originally. We had similar ideas. Tim said the Joker should have a humorous dark side to him. Burton is one of the great movie makers. I think the world of him. He's the most unassuming man. And he doesn't feel pressure. That's what I love about him. Once he's in there, he's smiling making the movie. That's it!
