It's always lovely to be part of a project that, on a creative level, is done for all the right reasons.

The last two days of shooting ('Harper's Island') was probably the most hardcore, the coldest anyone has ever been. It was like your head was freezing, and my motivation for most scenes was, 'The minute this scene is over, I'm heading straight over to that heater to get warm.'

Thankfully, the life of an actor can be quite balanced anyway. If you look over the course of a whole year, you do tend to have periods of down time. So, it's about managing the balance.

I just want to continue to be challenged and to keep getting better and better. I don't ever want to lose that or become complacent or pulling tricks.

In life, you're supposed to get wiser, so as an actor, even just through your own life experiences, you're already richer as a person and have more to pull on. And this job is great for the places it takes you to, the things it makes you interested in and the skills you get to learn.

You don't want to get pigeon-holed. So, I always get attracted to parts that are different from the previous ones I've played.

As you get older, you like to think you get better because you're learning more.
