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.

When I'm drawing a bottle or a town or a market, I transport myself there. So I start drawing everything that I'm looking at while I'm there. Here's a guy selling the meat, and he will have a hook, and you start adding things, and it's a lot of fun.

The Boogeyman is your conscience. The Boogeyman is the result of your own bad behavior. I love this Boogeyman.

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."

Many of the American cartoonists that want to have a job and go so much for the total right without thinking, sometimes they get a slap on the face when their politician lets them down. So it goes on and on. The thing is staying in the middle and not getting committed, trying to get the best of both and do that with a sense of humor.

At the end of the '60s, I was trying to enter the world of comics.

Once you've established where you are, you go to the character and elaborate on expressions and action.
