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've got plenty of train memories. I was sent to school when I was eight years old in 1948 in Kent. So I had to go through London in 1948, just after the war. Many ,many strange experiences.

Bong Joon-ho is enormously sensitive to performance. He knows what he needs to see and that's all he needs to shoot. He is so daring. We don't do that in the west. We shoot everything.

I first decided that I wanted to act when I was 9. And I was at a very bizarre prep school at the time, to say high Anglo-Catholic would be a real English understatement.

If you've got a great crew it's intense, but its quite short. 'The Elephant Man' was longer than most, for an independent film. That was a 14 week film. But it was because of the intrinsic difficulties. We had to invent a different way of filming, because the makeup was so long. A working day for me with a full makeup on was nineteen hours. So obviously you couldn't do that twice running.

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.

The British tradition, basically, is to go to the character. And the Hollywood tradition, shall we say, is basically to take the character to the performer.
