I'm just thinking of 2001, which I think is the most expensive independent film ever made - which is great, someday I hope I will do one. But I know the parameters when I got onto this project - I have to take care of everyone, make sure that they are all on board, and this process interests me.

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.

Of course, from time to time, I want to do everything myself and be more involved on my own with the creative process. But I don't mind the collaboration at all.

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.

I've always loved 3D. In fact, as a kid, I was exposed to 3D at an early age because my grandfather was a specialist of 3D in cinematheques. And then my cousin put it in 'Science of Sleep' with toilet paper tube cities. But he was a specialist and I always wanted to do something in 3D.

I'm just saying to everyone. The director does not direct the trailer. It's an edited version that takes so many moments of the movie, sometimes it's not even in the movie. The director does the movie. So don't judge the director based on the trailer. Please.

If I have a good dream and I wake up happy. When I have an idea, I feel happy. Sometimes achievement and relationships can make me happy. I have a son and to see him grow - he's 22 now - that makes me happy.
