"I had had an inkling that was going to be the case, and I am thrilled that that has come to fruition," he says. "You would have lost a lot of stuff that you couldn't really afford to lose if you had had to do it as one movie. In the fourth and fifth films, there was quite a bit of stuff you could get rid of without actually changing the story. In the seventh film, there is no really obvious subplot that you can do away with and keep the story going along the route it has to. I was struggling to see how they could do it as one film.

"Of course, the challenge now - and this is up to people who are much cleverer than me - is to find the breaking point, because there isn't an obvious breaking point halfway through the story where you go, 'Ah, here is where we can start the second film.' There is a gradual and relentless building up of momentum in the story and not really a place where you can leave the audience, but I am sure they will find one."

"Jack does believe in the king and country thing," Radcliffe says during a break in filming "Harry Potter and the Half-Blood Prince," "but I think he also wants very much to prove himself to be a man, both in the eyes of his father and to himself, and also to escape from a situation that makes him feel horribly trapped."

"...It stopped mattering very quickly that I had played Harry Potter. After a while no one cared because we were all soaked through and freezing, and we were just trying to make each other laugh. It was totally life-affirming and great fun."
