Q: Rupert Grint (who plays Harry's friend Ron in the films) just described the final Potter film (to be released in July, 2011) as a war movie. Would you go that far?
A: "They've all stolen my line! My pitch (for Deathly Hallows 1 and 2) was that it's a road movie that turns into a heist movie that turns into a war film. I was saying it to Rupert and Emma (Watson) the other day. Damn it!
"The last movie is going to be really, really fast-paced and a load of action in it and it is like a war film. If we had done this book in one film, the stuff that would have got cut is most of this film.
"For me that is the most interesting part of the story, because it's where the characters develop and change.
"This film, despite the silence and slower pacing ... was the most chaotic to work on by quite a long way. It was mad. We all felt the pressure on this film to make it the best, because it's the last.
"Suddenly somebody might wake up one morning and go 'Oh I'm not sure about how my character is in this scene' or the writer would have an idea so we'd be getting re-writes for some scenes the day before they were shot. It was constantly moving and had a less settled feel than the other ones had had."
Q: After 10 years living with the Potter phenomenon, how did it feel at the end of the final scene of shooting?
A: "There was just some very primal reaction. When you've spent 10 years in a certain place with a group of people, suddenly that goes ... you do sort of go 'What am I going to do now?' It was bizarre, because I knew I was doing a musical next year but that was all done, I knew that was going to happen, and I knew there was a definite option of one of about three films ... but at that moment I was really thinking ... 'What am I going to without all of you?' because it was those people I had learned so much from.
"That was, I think, the main feeling of slight bereavement, but then four hours later I was on a plane going to New York where I was doing the Tony Awards the next day, presenting, and I was reading the script for 'The Woman in Black' and five months down the line I'm half way through shooting it, so we move on."
Q: Do you ever envisage a day when you may not have writers and directors falling over themselves to cast you?
A: "As my dad always says, whenever I'm looking at other scripts and not knowing which one's going to work out, 'Oh happy problem!'. At the moment ... it's an embarrassment of riches and it comes back to a quote that you often hear people in sports talk about which is: 'form is temporary, class is permanent.'
"That's what I want to use the next few years to develop myself as -- into somebody who everybody knows wants to be around for a long time and I'm going to do that hopefully through choosing very classy projects like The Woman in Black."
