The more I love the character, the harder it is to get it wrong. I have to get to a point that I can speak for them.

I think if you had to map that out at the beginning and you said, "Right, sit down, this is what you're going to be doing," you'd probably freak out. But I'm someone who really enjoys not being himself. So if you consider that, then it all sort of makes sense.

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.

It's usually very, very hard for me to pick up a script that was written and try and see myself as a part of that, especially when you're used to performing all your own material. It's OK with drama, I like being handed great material but I think with comedy it's far more personal and probably a lot harder for me to find a fit.

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.

I would never say never to returning to comedy.

I think you need to be able to see a lot of negative in things in order to extract material, so there's probably something to that. A lot of the people I used to work with were very, very, very unfunny offstage, so that's a pretty common thing.
