Usually, when making a film, the surprises are negative surprises. You don't get what you wanted or what you hoped for. The only nice surprises are those that are offered to you by actors when they offer you these gifts, when they are better and give you more than what you had originally conceived. That doesn't happen every day on set, but if it happens a couple of times in the course of making a film, you can consider yourself very lucky.

To me, it's far more efficient to mobilize the imagination. It's far more efficient to hear a creaking step, for example, than to see the face of a monster, which usually looks ridiculous, and where you know that the blood is ketchup.

Writers and filmakers, that is, people who describe the world, suffer from an occupational disease. They never experience moments in life quite spontaneously. You always look at yourself from the outside. Even as a child I always observed myself and the world. I believe that everyone who chooses this path in any way, who chooses to be a describer of life, suffers from this condition. It's like a mental obsession. It can be a great pity too. It robs you of a certain joy in spontaneity.

On the set I make jokes I can't get too involved, or it turns into sentimental soup. I try to keep it light.

It's impossible to consider living without ideals. However, when ideas lead to ideology, that's a very dangerous thing. Ideology then leads to creating the image of an enemy, and it leads to the murder and massacre that we've seen since the beginning of time.

What I like are films that take me seriously, that don't treat me as more stupid than I am.

It's difficult because you can't generalise about these things. But in essence, you deal with children as simply as you deal with actors - you have to show a certain sort of respect. You deal with them lovingly and protect them, but if you protect them enough then they're open to engage with what you want to do with them.
