Often I don't read novels. The script is more important, that's the springboard to your imagination, really. Peripheral information can be interesting to read but you can't use it when it's not in the script.

I certainly don't see myself as Caligula.

I was keen on sports-that's how my nose got this way. It's not actually broken; the nose was just pushed up a little bit and moved over. It's an aquiline nose, quite Irish.

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.

I have lots of favourite memories but I can't say that I have a favourite film.

My springboard is always the script. Even if the script is taken from a novel, I often haven't read the novel...

By the time I came to do the final ones [Harry Potter's film], I was working on something that was massively successful. There was a huge difference in indulgence and all sorts of stuff. A very big difference in peoples' attitudes. They were very pleased with themselves. In human terms, it was quite interesting to see the difference.
