So I went to George and told him I had the opportunity to become the figurehead of a government safety campaign, and he agreed to give me the week off and reschedule shooting!

George Lucas was casting about and had heard favourable things about my work in Clockwork Orange and asked me to come in, which of course I did even though no one knew what the film was about!

I do remember smiling quite a bit inside it though since I knew it wouldn't be seen on film - so of course while the poor planet is being blown up I'm smiling and laughing like mad!

I'm also involved in the rights of the disabled and do some fundraising for that and I thought it would have been a big boost for the campaign but it couldn't be worked out.

I've seen the teaser trailer for Revenge of the Sith though and I think it will be excellent.

The ability to destroy a planet is insignificant next to the power of the force.

I think if you think of our lives as musicians, it's craftsmanship. We're not artists, we're more artisans. You know, I don't think we view ourselves as musical geniuses who can just make some sort of wonderfully beautiful record out of nothing. It's something that we work at. And if we keep working, hopefully we'll keep improving.
