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.

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

I'm a huge fan of classic sci-fi.

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

I love motion capture. I think it's the best thing, ever. It's wonderful. It gives you an incredible freedom to just play things out.

I seem to be incapable of playing that guy that always does the right thing, who always responds well in any circumstance.

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.
