Encourage your kids to be creative. When you see them tracing a character from TV or a comic, say something like, 'That's nice. Now how about you create a character yourself?' Keep kids curious and excited about creating.

The Joker is a tremendous vehicle for talented actors. Cesar Romero's was a bubbly, lunatic criminal. Nicholson did him as a vain, preening manipulator. Heath's performance of the Joker was remarkable, too. His was a low-simmering crazy street clown. Joker can be played all these ways, and they're all true.

A lot of times, female characters - particularly the villains - come off as very one-dimensional. They get the short shrift in that they're only given the snappy comeback, or they're relegated to a very stereotypical role. I want to know what's driving them - that's what's really interesting.

It's wrong to become a bully yourself or to take it out on other people, and in my case, I just retreated to a place where I was safe. And that place was my imagination, books, and television.

Batman doesn't use a gun. When Bruce Wayne thinks he had to resort to a street thug's level to defend himself and the girl he was rescuing, he decides he can't be Batman anymore.
