You look worldwide for the great leaders, and they're pretty thin on the ground, and of course the problem is unless you're squeaky, squeaky clean, something is going to come out of the cupboard. Most people aren't squeaky clean. Most people have fallen by the wayside once or twice in their lives, and because the world is so transparent now, I think they're very fearful of running for office. It's a huge shame, because often people who have really lived and are amazing people can be brought down by a past indiscretion.

Never played a video game. Actually, I try to keep them out of my house.

I get bored very easily, so I love doing different things, changing, doing a job for a month and then doing another one for six months and then moving into a different group of people. I love being able to stop. That's one of the greatest benefits we have in our profession.

To be an actor you need various things. You need to have a head for choosing the roles. You have to be, hopefully, easy to work with so people enjoy working with you. You have to deal with missing roles, with not being asked to work, with doing good work and then being castigated by the critics for it. You have to have a skin that can deal with all of that. I, fortunately, seem to have the makeup which allows me to deal with the business. I mean, not as everybody.

I've actually always been fussy about the work I do.

You have to communicate on a much greater scale. With a camera, you can use the flick of an eye. On stage, a lot of other things are happening that can pull focus or energy. You're always thinking the same way, but you have to amplify your thoughts with the volume of your speech and the ways you use your whole body to communicate what you're feeling. It's a little bit different from film.

I'm a complete libertarian. I think it's very, very dangerous. I really mean that. I think the smoking ban is a tip of an iceberg of society - the leaders of society telling us how to be. I think it's not their business. It's an attitude where the governors think, 'We know what's best for people, and they're so stupid that they would only not do it if we ban it.'
