I've actually usually been wary of taking on science fiction as an actor because it's really tough to do. It's really difficult to execute. There's often lots of prosthetics, green screen and special effects, and it can get very technical.

The process of acting, not necessarily the business of acting, but the actual doing of it in the moment is my greatest kind of personal passion, the thing that brings me alive the most. Also, my two children.

Money is tighter now, with the advertising dollar spread a lot more thinly across a whole range of media because of the Internet. It means the television networks have less power to produce shows, and TV is where most Australian actors make their money.

A long-running TV series is a beast in that it demands you stick to one character over a long haul.

The truth that I know for sure is that I may have an opinion, but I do not know the truth, and the other thing I know for sure is that certainty is the root of all ignorance and the root of all evil.

I think that the way of bringing realism into fantasy is to treat it as the commonplace.

When I really get invested in something, the one thing that really disappoints me is when it breaks its own rules.
