I think that you always have something left, that you take something of the character with you.

The idea is that Jodie Foster is with her child and she's going back to New York from Germany with her husband's body. She loses her child on a plane, and you think, 'How can that happen?' There's no record of her having brought a child onto the plane, and the captain is left wondering about whether she's telling the truth. You never really know if she's telling the truth or not.

I sometimes find that playing the bad guy, or villains, or psychopaths tend to be much more psychologically rewarding. And you can really push it, you can push the limits, and get away with it.

I'm proud of Lord of the Rings. I think it's a once in a lifetime role, and a once in a lifetime film. It was made with so much care and passion and meticulous detail and everybody was so behind it.

Oblivion is something unique, an entertainment experience unlike anything I had seen before. I decided this was a project I really wanted to work on creatively, and I hope fans of the game enjoy the results.

I think everybody's got different methods of working which suit the particular individual. Mine is to sort of play the part, and give 100%, to concentrate and focus on it while I'm actually working, but then leave it behind until the next day.

I go to see my kids in school plays, ... I watched Lorna in a concert at the Westminster College of Music the other day and it was amazing. I felt very proud and surprised. I don't know why I was surprised, because I've known her for 17 years, but I've never seen her do anything like that in front of an audience. It's brave, it's uplifting.
