A comic book is the opposite of a cartoon. In a cartoon, you want to simplify the idea, so when they look at it at a glance, they get it. Boom. Simple. Direct to the point. But when you're drawing Groo, now it's a narrative, a story. You want the viewer to get involved in the story. You want him to feel like he's in the town to follow your main character. So I love to add lots and lots of things in it. Things that people will enjoy going back to and say, "Oh yeah, that's how a market must have looked in this fantasy world, with people selling meat here and dishes here."

I have always loved horror very much. I used to write stories for DC's House of Mystery. It was one of my first jobs writing for comics, and I loved it.

I think that true horror is accomplished by slowly getting into your brain. The old way is much more scary.

The reason I love comics more than anything else is that the longest story will be just a few pages. With a novel, it takes so many pages to get to one thing happening.

My father was very political. But he told me, "Be very careful when you get into politics, because there's no black and white. There's an in-between in everything. So look at that side, don't take one point, because then you are negating half of the other people. Try to find the logic on a problem, something that you believe, and take the position that you believe, but be very careful about it." So I was very well trained in that aspect.

If the gag is complicated, you spend more time thinking about the way you’re drawing it.
