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 sort of leave the character at the end of the day. I don't carry anything around with me - no excess baggage or unnecessary thoughts. I think it's too exhausting to do that. To put things into perspective - your work is your work, and your leisure time is something else.

My family thought the fascination with acting was just another fad.

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.

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.

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.
