Let's put it this way, when I was casting, I cast Viggo first and then found someone who could play his wife, rather than the other way around. So for me he's still the lead character.

Each kid has a different level of expertise and some of them are very raw and inexperienced and some are incredibly mature and experienced. So you just have to go with what they are rather than have some abstract technique that you're going to try to apply to them.

For example I don't work with William Hurt the same way that I will work with Viggo. They're different guys and they work in different ways. So a good sensitive director has his general style and technique and personality that he uses but you don't impose that on the actors.
