Acting is really instinctual and I think you can overanalyse what you're doing. A lot of it has to be based on instinct.

The stories I'm interested in are challenging ones, and maybe that requires a little bit more of you. I love my job and I want to earn the right to do it every single day.

To be honest, I would like to have worked with Peter Sellers, because when people talk about classic British actors, you talk about Lawrence Olivier, and Peter Sellers was just in the most amazing films.

In my experience of doing physical scenes, half of your energy is spent on trying to get the other actor to enter into it physically with you. Most actors don't want to hurt each other.

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

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.

The sixth Harry Potter film - I don't like my performance in that film at all.
