Because it's me playing the character, trying to find a way to make it believable and entertaining and interesting.

There's what is on screen and then for us, it's if you get along with the people and enjoy showing up at work.

What's funny is that there's a lot of great Australian actors in American movies but you don't often hear them do their Australian, original accent.

I always think about Katharine Graham - she was the publisher of The Washington Post. In her autobiography she talks about the way her parents met. Her father was, I think, in New York just walking by on his way home and looked into a store and saw the lady that became his wife. It was just pure luck. And she said that it once again reminds her of the role that luck and chance play in our life. I really believe that, too.

It isn't so much that I choose the roles - I mean, I guess there's a little bit of a selection process - but it's more just what people offer you.

Film is definitely a director's medium. They're responsible for the look and everything, and you're a part of that process as an actor, and you try to contribute to the story. But I think it might sound a little pretentious for me to say I think of myself as an artist. I think of myself as a creative person.

The Australian accent just a very lovely accent and it doesn't have the pretention maybe of an English accent, but yet seems a little bit more exotic than an American.
