Lord of the Rings was just so much enjoyment. It was over about the space of a year that I was filming. It's one of the most enjoyable things I've ever done, so emotional.

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.

Everyone was very deeply involved in the world of 'The Lord of the Rings'. From the wardrobe department to lighting, all were fascinated with the story. This is something that does not happen usually.

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

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