So when you read the book, and you see what happens, did you become excited?
That's been the case with a lot of the later books, really. The character's had a lot more dimensions to him. In previous films Ron was usually quite scared all the time, that was always kind of him, but it was great to see that there was a lot more heavy emotion. Because he really falls in love, so there's all that story, and that really develops in Part Two particularly. And then there's the family stuff as well. There are some quite dark things that I never really got before with Ron.

He went in a dark direction in the last film too.
Yeah. It was great to have the opportunity to do that, to get my teeth into something different. It felt like a different character really, it was cool to find that side to him. It's all kind of embedded in me; we've almost become the same person over the years, sort of merged into this Ron-pert. Even now.

What was it like shooting that final battle?
The way we filmed it was confusing, because we filmed both parts simultaneously. So some days we'd be doing a Part One scene, then a huge battle. It was quite hard to keep track of what was going on in Part Two, so I'll be quite interested to see how it's all been put together. But the battle sequences are great, I think. It was just so big and epic; there was one scene in the courtyard where it's one big, continuous shot and they have five cameras picking up everything, and there's giants and fire and big craters. Even for Harry Potter, it felt really huge. These sets, they did actually destroy them. The rubble you see is actually the set falling apart. It's quite weird seeing all these sets that I've grown up in as piles of rubble, there's something strange about that. But it's going to be amazing.

Was it a case of 'no acting required' as Hogwarts comes down there?
Yeah. It really nailed that down, that this was the end. Seeing the Great Hall... The place had become quite a familiar one in our lives; we'd spent a lot of time there. And now it's on fire. There are dead bodies, dead children everywhere. It's really dark.

Did you feel sad about finishing? Or did you have a sense of finally feeling free?
It's a mixture of both really. The sadness didn't really hit me until the last day. We were saying goodbye and it was quite an overwhelming feeling that it was all coming to an end. I remember packing up my dressing room, that was... I had toys from when I first started. It was really weird doing that, and it all hit home how much this has been a huge part of my life. I find it hard to remember life before it really. It still hasn't really sunk in, I think. I don't think it will for a while.
