Developing characters is a collective process, on one hand; it's an individual process on the other. The truth is rarely pure and never simple, as dear Oscar Wilde would say. A great of it, of course, is, you collect as much information as you can and then you put it into the mulberry of your mind and hope that you come up with a decent wine. Sometimes you do; sometimes you don't.

I loved working with [ Lars Von Trier], but I've done two films before, so I was quite used to him.He's a man of incredible moods of course, but he's also a hugely perceptive man, and there's no getting away from that. And he's able to put that perception into something like film, so we're very lucky.

There are certain people that when they ask you to do a film, you just say, "Where and when?"

The director [Elfar Adalsteins] came to me through my agent and I had a read of the script [of the "Sailcloth]. I thought immediately this is someone who is writing for the cinema. Not having to go through the tedious business of taking something from literature and making that awful leap that is so difficult to make anyway, from literature to cinema. It's refreshing to be able to deal with a subject like that, to be written where the driving force is the image on screen and you don't need any words. The more that we can do that [in film], the better.

There is always a better choice that you were unable to quite touch with a single stroke. Even in acting, there comes a point, like a painting, where you have to say, "That's it. I can't go any further with it." And sometimes, you say, "I'm really pleased that that's where it's finished up." Other times, you think, "I don't think I really quite got there, but I haven't got time to go any further." Rather reluctantly, you have to say "That's it."

I loathed school. I don't have an academic mind, and besides I was so bored by my teachers! How teachers can take a child's inventiveness and say yes, yes, in that pontifical way of theirs, and smother everything!

Elephant Man [movie] was much more difficult physically. This had a couple of days. It was quite tricky. I had my leg strapped up behind me and I am a little older now. It was all marvelous, though. He [Bong Joon-ho] is one of the most fabulous directors in the world.
