I carry music in my head, so I don't need more. It drives me nuts that, in hotels or on boats, people seem to think you need music 24 hours a day.

I have no idea what my persona would be. As far as I'm concerned, I'm changing all the time.

If you only took on roles that had the same qualities, then I suppose it might make a critic feel better, if he can see some kind of bedrock. Perhaps that's the old definition of a star, someone who's always going to come up with the same goods. But it intimates limitation to me and I don't want to think of the job like that.

My phrase has always been that I am looking for the versatility of theatre in film. I think I have been quite lucky in that so far.

And there's no way I'm going to do Dame Edna.

I'm not someone who can lie on a beach and do nothing. I am not sure what you are supposed to do, so I get bored. I prefer to have a purpose, such as going to Alaska to see orca whales.

For years, I never knowingly went on a holiday. When I travelled, it was for work. Now I am a huge advocate, particularly to places which have amazing wildlife, such as Antarctica, India and Patagonia.
