I like to keep myself in shape. I run and do weights when I go to the gym.

I'm still Sean that me mates went to school with, not Sean the film star. And that's the way I prefer to be.

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'd been trying for a while to get parts that weren't just the English bad guy, so it was quite refreshing to be playing someone who was a compassionate, decent guy.

You've only got to walk into a pub or a café or anything and you'll find people talking about topics they're very unhappy with. You feel as though things are being eroded and people don't know where they belong anymore.

Sharpe is my favorite role of all that I've played. He's a very complex character. He knows that he's a good soldier, but he will always have to fight the prejudice of aristocratic officers because of his rough working-class upbringing. On the battlefield, he's full of confidence - but off it, he is unsure, a bit shy and ill at ease.

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.
