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 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.

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?'
