I have seen the Gore documentary 'An Inconvenient Truth,' just released in the States, and admired the acutely revolutionary delivery of the slideshow assisted talk he has now been giving for some 16 years.

I do get funny people sometimes coming up to me in supermarkets in America with my picture in their pocket, which is a bit strange.

I like working on stage because there's something very immediate about it, that interaction with an audience where you immediately hear their reaction, or feel them, whether they're with you.

For a woman to say she has had a dalliance with another woman is quite trendy these days. I do not like trendiness. Life isn't about dalliances - it's about individuals. You come across people in your life that you find very interesting. It's not about something flighty.

I play the guitar. This year at the Sundance film festival, I joined the band from 'The Guitar' on stage. We warmed up for Patti Smith, and then the director Michel Gondry got on the drums to play some songs from the soundtrack to his film Be Kind Rewind with Mos Def. It was pretty mad.

You can't ignore the system and the power you acquire as an actor if you're in films that are successful.

What am I doing in this silly showbiz life? I do wonder that sometimes.
