I was being a sort of rebellious teenager, really. But there was never any point at which I was considering leaving Harry Potter. If I were to stop acting, it would have been after. As long as they kept asking me to come back, I was gonna keep doing it. 'Cause I loved the story! There's no way I would have left.

I think David Yates was just like, "You've got on with it for a few years, I'm gonna let you off the hook." And also, I think it's because the action side of stuff that we were doing, it was going to be very difficult to do all that with all the prosthetics on. It was gonna be hard work, and I think they just said, "You know what?" I think they put a level of trust in me, as well. They said, "You know, we're gonna let Neville Longbottom lose the fat suit, lose the teeth, lose the Adolf Hitler hair."

Leeds is quite laid-back.

It's always been my dream to be in a war film.

I'm very comfortable being at home and keeping my head down, really. It's nice being invited to night clubs and stuff, which is nice once in a while, but I prefer to kind of keep to myself.

The great thing about filming a film is that you all have your final day's shooting, but you always know that you're all going to be coming back for the premiere.

At that age, filming Harry Potter, I never contemplated. I just went in there and did my acting. I never thought, "What's the character actually feeling here? What's he trying to get across?" And never looked at it from that classically trained actor's point of view. And so when Jason Isaacs started throwing up these ideas, I thought, "Whoa. What an interesting way to look at acting." Which is why, again, I would do theater.
