The real challenge of acting for me, I suppose, is just getting to know a character very, very well and just applying what I know about them to every single scene. That's what it can be broken down to.

One of the things that I cannot fathom is young actors who will not audition and won't read.

I'm sure when I have a nostalgic, teary moment in 10 years time, I'll try to put the glasses when I was 10 on and cry to myself in front of the mirror

I think Harry Potter's very important. Every opportunity I will get for the rest of my life, I would not have got if it wasn't for Harry Potter. And it would be height of ingratitude if I was ever anything but proud to be associated with these films.

I would consider doing any part as long as the script is good and the film has an interesting director.

I had one relative who passed away but fortunately none others. So my sort of experience of it is quite limited, thankfully.

There is always this thing of will you get too old for your part? But people are playing a lot younger than they actually are in real life. I don't think it's as big an issue as a lot of people are making it out to be.
