People say you never retire in this [film] business and I say, well, not until they retire you.

Each day, as you get older, there is a new perspective on life. It's a progression of some sort.

On the other hand, you get other films that are spread over a much longer period of time and it's entirely exhausting. But there's always light at the end of the tunnel with a film.

The only concession you can make is to what you believe is right.

I mark a script like an exam, and I try not to do anything under 50 per cent. Similarly with the part. And also film is a peculiar thing, parts don't necessarily read in script form anything like as well as they can do when it comes to materialising.

The clergy is in the same business as actors, just a different department.

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.
