That's the happiest I am, when I'm doing great work.

It's been great, I have to dig deep for really raw emotions and at the same time I have to use my intellect to say the ridiculous medical jargon while acting and treating a patient and then I have to try to have a personality and emotions as well. So it is definitely hard work.

The message is one of the beautiful things about the film. And I think part of the appeal is simply that they are prehistoric creatures, they are no longer around and that makes them magical and makes us feel quite emotional, because we know that those creatures did not survive in the long run, so there's poignancy in their fight for survival.

Acting is kind of a calling for me so I'm just happy to be there and do great work.

When I started performing I was like, "Holy hell, how am I going to survive this?" I was giving it my all in 15 minutes but now I had to do it for two hours.

I think as you mature as an actor things open up to you in a lot of ways, especially if you do work on yourself.

I was just school class clown and that was it. Someday I'll get a job as a cab driver or whatever.
