I love the challenge of playing characters forced on life-changing emotional journeys. To work on a project with Billy Crudup and Sam Rockwell is just a dream come true.

I'm just trying to choose interesting, quirky projects or things with interesting directors or just movies that have a lot of people I like attached to them so I know I'm going to have a good time.

Sometimes a script comes along that really makes you sit up and pay attention... 'Life at These Speeds' has an emotional intensity that really kicked me in the guts.

One of the biggest things I used to struggle with was about things like going on holiday. Whereas all your friends can talk about something and plan something all year long, I know that I'm probably going to be away and I'm going to miss all of it. If a job comes up, you just can't be there.

It's better to think of life as a proper journey with a beginning and an end. Maybe, I can settle for being immortalised on screen.

The best thing I've ever done for a girl hopefully is make them happy. Isn't that the most romantic thing you can do?

I don't think I've reached perfection by any stretch of the imagination, but maybe someday I'll become a perfectionist.
