I wasn't aware of my dad being an actor when I was young. I remember there was an Australian children's entertainer on television called Ralph Harris and when I'd say my father was an actor, kids would say, you know, 'oh, is he Ralph Harris?' And I had to say no and then they would lose interest.

My father was a Catholic, but my mother wasn't. She had to do that weird deal you do as a Catholic - they deign to sanction your marriage and you have to bring your children up as Catholics.

It's important to keep auditioning. If you're auditioning for something, you're auditioning for a role that people can't see you in and you need to convince them that you're the right person.

Often in films there's more of allowing the actors to make the dialogue fit better in their own. Also, you get to a location and the geography is different, so the lines don't line up the right way, so you do have to change stuff.

You can't really do a lot of research for being a mass manipulating, murdering super-villain.

If you want to do your version, go off and write it. You bring your knowledge to it, and you can use that to shape it and color it, but it's someone else's version of that character. You're not actually playing the real person.

I remember thinking, 'I'll audition just once and if it doesn't work out I'll never think about it ever again.'
