It's quite a dangerous career move to go wilfully on making films that may not find a distributor.

I felt, you know, body and soul, as it were. But, of course, I mean, I - at that age, I didn't think in terms of being professional. I didn't know anything about it. That happened later.

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.

A very, very impressive director, Tomas Alfredson. It's only his second film [ 'Tinker Tailor Soldier Spy'], but he's a real find.

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 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!

I think particularly Daniel [Radcliffe], he knows what he's doing. I'm sure he'll finish up a producer. He really realized what it was, knew the size of it. And it was gigantic, the biggest franchise [Harry Potter] in history.
