I guess I've been fortunate in having an ongoing film career while being based in Melbourne. I'm happy to commute. A day on a plane. Come on. It's easy.

I didn't know the Green Lantern comics at all. I was a Superman reader.

I went to England in the '70s, and I was in my early 20s. There was still a residue of that era of being an underclass or colonial. I assume it must have been a more aggressive and prominent attitude 40 years before that, because Australia internationally wasn't regarded as having much cultural value. We were a country full of sheep and convicts.

There's often rarely any dialogue in a sex scene. With your fellow actor, it's good to talk about what the unspoken dialogue is, that's happening in the scene. You've got to play something rather than feel self-conscious or exposed.

I knew all about Edward VIII's abdication, George VI becoming the king and having a stammer, but nothing about how he got rid of it.

I've discovered I prefer to prepare a few notes or actually write the speech so I can really hone it down to hopefully be entertaining, try and get a laugh at least by the second line, and then say what you need to say.

Like any classic you hope to get rid of all the varnish that's built up over the centuries where people expect it to be in a certain way. It's a mighty play. It's about a very old king who also happens to be a very old father, so you've got the state and the domestic levels in there together. It's a story in extremis. Everyone knows the end, there's only two people left alive.
