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.

In orthodox film-making, you never shoot sequentially - but with improv, obviously every move you make has a knock-on effect; it is a cumulative process. I have improvised, on the non-scripted 'Timecode.' It can become entirely indulgent: actors smashing crockery and competing verbally.

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

I like acting in London-not least because it means I can go home after the show every day, rather than being on location making a film.

It's always a help when you have worked with someone as you've got to know them a bit already.

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.

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.
