American writers often say they find it difficult to write Superman. They say he's too powerful; you can't give him problems. But Superman is a metaphor. For me, Superman has the same problems we do, but on a Paul Bunyan scale. If Superman walks the dog, he walks it around the asteroid belt because it can fly in space. When Superman's relatives visit, they come from the 31st century and bring some hellish monster conqueror from the future. But it's still a story about your relatives visiting.

Talking to oneself, I have often thought, is the best way to be sure of intelligent and witty conversation.

When ["Wonder Woman" creator William Moulton] Marston died in 1947, they got rid of the pervy elements, and instantly sales plummeted. Wonder Woman should be the most sexually attractive, intelligent, potent woman you can imagine. Instead she became this weird cross between the Virgin Mary and Mary Tyler Moore that didn't even appeal to girls.

Superhero science has taught me this: Entire universes fit comfortably inside our skulls. Not just one or two but endless universes can be packed into that dark, wet, and bony hollow without breaking it open from the inside. The space in our heads will stretch to accommodate them all. The real doorway to the fifth dimension was always right here. Inside. That infinite interior space contains all the divine, the alien, and the unworldly we’ll ever need.

The more I think about it, the more I realize that schools are just factories for turning out robots, that's all. They get you when your small and vulnerable and they take all the human parts away, bit by bit, until you're just a wind-up toy. Turn the key and set it running. And the toy goes to university, gets a job, settles down with someone nice.

I guess my inspiration is this - I like to pretend that every story that ever happened to 'Batman' was real and is part of this one guy's life.

I just do what I do because it feels right. Other people attach labels to that.
