I think love can come fairly easily and grow - but really liking the core essence of someone is a much harder thing to bottle. If you have both, you're in pretty good shape.

If you're lucky enough to be involved in a film that's about something very real and that you hope will continue to hold up in 20 years' time it just gives you more energy and makes it feel all the more worthwhile.

It's got to be a challenge but at the same time you have to feel as though you can play them - it's really dangerous to want to be a part of something just because you think it's going to be great. I've been sent plenty of scripts where I've known that it's going to be a great film and a successful one, but I just couldn't convince myself that I was the right person for the part. So, I think you have to be careful with that.

It really depends on the director. I think quite often, it's not what you expect. The most serious film can be the most fun. The one that's supposed to be fun can be the most serious. I don't think there are any hard-and-fast rules. I just think it really depends on your director and what the general vibe is.

I guess on a base level that's one of the first parental instincts that you have with children in Australia is learn to swim. Not only learn to swim but learn to swim strong.

I was a fan of the television show as a kid but I wouldn't say that I've followed all the movies or anything like that. But I was a television junkie as a kid.

I hate being clean-shaven. My daughter gets very upset if I shave and says, 'Bring back the spikes, Dad.'
