When you create a church, an institution, and you create a dogma. When you create an ideology, that's the danger. Communism, too, is a beautiful idea, but millions of people died when communism became an ideology.

My father and I had a good relationship, it was very relaxed. He had a lot of humour. He looked a little bit like me, although he had no beard. He had the appearance of a very elegant British-looking man.

What we're doing for another person is more important than what we're feeling for them.

I love actors, both my parents were actors, and the work with actors is the most enjoyable part of making a film. It's important that they feel protected and are confident they won't be betrayed. When you create that atmosphere of trust, it's in the bag - the actors will do everything to satisfy you.

My films are intended as polemical statements against the American 'barrel down' cinema and its dis-empowerment of the spectator. They are an appeal for a cinema of insistent questions instead of false (because too quick) answers, for clarifying distance in place of violating closeness, for provocation and dialogue instead of consumption and consensus.

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.

You become a film critic because you're interested in film. I don't know whether knowing so much about cinema leads you to make better films, but it certainly can't hurt.
