I did mega-training with ex-military men. I'd be in the gym for two hours after a 12-hour day on Spooks, and it was so hardcore I'd throw up. I stuffed myself with food and drank protein shakes to bulk up. I used to be a dancer, but I had to strap my weak ankles every day and strengthen my wrists so I could hold a machine gun. My body just wasn't up to it.

I think there was a pretty smooth hand-off from the administration of President Clinton to the administration of President Bush, particularly in the counterterrorism area. The reason I say that is because there was, for transitions, I think a stunning continuity.

Tolkien was, I believe, writing about his experience in the First and Second World Wars, where he would have spent a lot of time without any female contact. He was part of the fellowship of men who went to war, and I think, really, that's what he's writing about.

I have a bit of pride, which is always my downfall.

I can work hard and be disciplined like a soldier, but I could never reach their level of fitness. I have a whole new appreciation of soldiers. I saw myself on screen and thought, 'That body is so not hard enough to be a soldier.'

Iran has interest in seeing that the Shia population of Iraq basically adhere to a line that comes from Iran.

I'd have described myself as a Tolkien reader before this, but now I'd describe myself as a Tolkien geek.
