Anything which retains interest is optimistic. When the characters become disinterested, it's pessimistic. Does that make sense?

Also the wonderful thing about film, you can see light at the end of the tunnel. You did realize that it is going to come to an end at some stage.

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.

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.

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."

In the end, the game is the same. Football is still football. Now, they may play with different formations, they may have a different idea of training, but the game doesn't alter. I don't mind how any performer - indeed, why should I? How arrogant of me if I did? - manages to get to what they have to get to. It doesn't matter how you get there, as long as it isn't going to destroy other people on the way.

'The Elephant Man' was hugely enjoyable to do. I thought the one stage, when Chris Tucker did the first makeup and it took 12 hours, I thought they'd actually found a way for me not to enjoy filming.
