I had no intention of being an actor. I was quite good at it. I was pretty capable at other things but never any good at anything.

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.

You only have to pick up a paper to see the sort of scams and injustices that are out there. There's a sense that people don't belong and just aren't very happy. They're outraged, in fact, and they're being shafted left, right and centre.

Lord of the Rings was something I always wanted to do. I read the book when I was about 25, and I was always hoping if it was ever made into a feature film that I would be involved in some way. And then I finally got it, and I was over the moon. It was fantastic news.

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