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.

We shot ['Sailcloth'] five days down in Cornwall, and you couldn't have asked for a more beautiful place. It was a couple of tough days at sea, but when I say tough it was still enjoyable.

Snowpiercer has both [optimistic and pessimistic]. It was essentially optimistic. The most pessimistic was my part, because of his knowledge. He knows how it started. The status quo, he knows, has to be maintained, otherwise there is no chance. He knows that this revolution is completely understandable and is also commendable. He also knows the negatives. In the end, that's not a very positive position to be in.

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.

I have lots of favourite memories but I can't say that I have a favourite film.

We are all racing towards death. No matter how many great, intellectual conclusions we draw during our lives, we know they're all only man-made, like God. I begin to wonder where it all leads. What can you do, except do what you can do as best you know how.

Acting is an imaginative leap, really. And imaginations prosper in different circumstances. And it's being able - I can't tell you how one does, but one tries to read those circumstances correctly.
