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.

I think it would be very difficult to play somebody if they didn't think they had any virtues or redeeming characteristics.

The first film is everything you want to say and how you want to say it. Lots of directors will do that and do it really well, but the second film is not so easy.

I thought ['Sailcloth'] was a terrific script. Elfar Adalsteins, the director, is bound to be a director we'll hear from, and the whole thing was really enjoyable.

It's quite interesting, looking back at the first one [film about Harry Potter], nobody knew whether or not it was going to be successful as a film. The books were of course already very successful, but that's happened before, where the books were successful and the films weren't at all. But it turned out that they were.

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.

Once you've started to dig a hole, you can't get out of it.
