I suddenly became aware over the last couple of years that I'm in my sixties. I never thought about it. I thought I'd better start acting my age or find roles that are going to be interesting to me in the sexagenarian repertoire, because it's not what you do in your forties or fifties.

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.

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.

Most films I've worked on have had large casts, but they've been wonderful people. I think the monkey in Pirates of the Caribbean is the most temperamental costar I've had. It would throw tantrums like you wouldn't believe.

What I appreciated was the fact that the script delved into how Australians were - and still are - condescended to by the English.

That's one of those questions where somebody says "would you like to see more women behind the camera?" And then it becomes I must have interrupted the interview to make a platform stance. But, no, I do believe it. In Australia, per capita, we've got a slightly more balanced and healthier statistic than here. I've only just started working more regularly with female ADs and its just a beautiful, different energy on set.

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