I take my hat off to mums who have lots of kids. Anyone that says being a mum isn't a full-time job has obviously never had any.

There was actually a camera on your face. I don't know so much about the animation process but the camera was in our face so it could get expressions from our faces that would eventually arrive on the gnomes. It almost felt like you were cheating at times because it was a wee bit too much fun. You were in that box on your own. Kelly [Asbury] was in Toronto, I was in LA, so I was just on my own. I thought: "I can't be getting paid for this as well!"

Well, I'd never done an animated movie before, which is why I was so excited about doing it. It was one of the little boxes as an actor that I wanted to tick off. I wanted to do an animated film. So, after my mum got over the fact that I was never going to play Shrek's sister, this was the nearest I was going to get!

I've always been quite thrifty. I can't bear to spend hundreds of pounds on designer clothes. I shop in second-hand shops in Portobello Road and go to Sue Ryder.

I've reached a point in my life where going to the supermarket is a day out.

Americans are so direct. They'd ask me, 'What's your five-year plan? Do you have a five-year plan?' I don't know what I'm having for my tea tonight let alone a five-year plan.

My husband is always telling me: 'We're on holiday - we don't need to have an itinerary!' But I always want to see as much as I can. Sometimes, I come back from holiday needing a holiday.
