I don't like vampire movies or zombie movies. I went to see 'I Am Legend' with an ex-girlfriend the other day, and I immediately realised it was a zombie movie! You know what I mean? There are certain rules, and those rules are things that you've seen many times.

In a way, putting actors deep into this sort of complicated universe frees them from thinking about who they should be. They just are somebody.

When I was young, I would stay in my backyard and I would create roads and tunnels and systems. My uncle had a sawmill, and we had all sorts of pieces of wood, and we'd create a city. I truly believe that kids enjoy the box better than the car or the toy that's inside. So many times during Christmas, watching a kid, or even myself... There is excitement toward your toy, but then you put the toy on the side and something is created with the package.

My goal was to show that even if people work in a garage or a supermarket, they have very funny things to say. We never hear their voices.

If people don't like the trailer, then blame it on the people who made the trailer.

The problem is when you get forced to use ideas that aren't good. When I can filter the ideas and use the best of them, I am happy to collaborate.

Perhaps my favourite story is 'Le Passe-Muraille' by Marcel Ayme. It's about a guy who wakes up with a weird faculty that means he can walk through walls. He's a very shy clerk, and he uses it to get revenge, or vent his frustration.
