My favorite phrase, that a friend of mine who worked on the Potter films and was a lot older than me would use in front of me, and I picked up from him many great phrases - the English have a lot of great idioms for sweating. I don't know why that is. But that's what we do. I feel like it's particularly our country; probably everywhere has a lot of idioms for sweating. He always said, "I'm sweating like a glassblower's asshole," which I always found an incredibly strange and yet vivid image.

I used to be self conscious about my height, but then I thought, f*** that, I'm Harry Potter.

Working hard is important. But there is something that matters even more, believing in yourself.

To the children who loved Harry Potter, I want to say your enthusiasm was the real magic. I so enjoyed being on the journey with you. And to the adults who bought the Harry Potter books and devoured them, I just want to say, those books were for children.

Just keep acting is my plan, I just want to keep going for as long as I can. I've had a fantastic time on Potter, I will be very sad to leave it because every time I look back on one of these films, every scene I watch will be forever linked to a memory of what happened that day or something that was happening around that time in my life.

People tell me I look mournful. They say, "Cheer up, Dan, it's not that bad!" Sometimes, I just look into space, which freaks people out. If I was ever required to do anything other than look haunted, I could. I'm a happy person.

I certainly want to establish myself as an actor in my own right, rather than being just the actor who plays Harry Potter.
