Honestly, I like someone who is really grounded, super sweet, honest. I need them to have a sense of humor. I need them to laugh at what's funny, I need them to get jokes and be funny and be witty and sarcastic.

When I've written episodes of 'Doctor Who', when it comes to the monster chasing somebody, it's the Doctor and the companion, running down the corridor, being chased by a guy with a stick and a tennis ball on the end. Whereas, when I see the rushes of 'Being Human', we're actually looking at the werewolf, and it just looks real.

We're taking sports too far and starting kids too early.

After my first 'Sports Illustrated' cover, I felt terrible about myself for a solid month. People deal with models like they are children. They think they can pull one over on you. I'm not a toy; I'm a human. I'm not here to be used.

The 'Sports Illustrated' cover was the last thing I shot. That week, I told my agent, 'You know what, I really... I don't want to be a model anymore. I really want to do movies.' And I think he wanted to wring my neck at the moment.
