It's unbearable when someone changes around you. Just imagine that your life partner changes, then it is difficult to cope with. Or your mother. Or your father. They were strong and now they're like a baby - it's not so funny.

For me, it's always difficult when a historical film claims to depict or represent a reality that none of us can know, that is always different. It's always the case. We never know what happened then. So my approach with the narrator is to question that, to leave that open, to underline the fact that this is uncertain.

When making a film, I'm never concerned about whether the theme is new or whether it's been done before in cinema or not. I'm led to make films if there's a theme that interests me or I experience something in my own life that confronts me with something that I want to deal with.

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.

If you do an original film and you want to cut a scene out you do it. But when you do a shot by shot remake you don't have that option and every scene has to work again.

I'm not someone who enjoys long talks, long rehearsals. I'm very technical: I tell my actors, you come in, you sit down, you pick up a coffee, you look here, you say the line. We try it with the cameras rolling, and if it doesn't work, we adjust it until it does. It's very simple.
