I was on my own, living in Los Angeles, and I didn't know my way around, so I thought I'd walk everywhere. Well, that certainly got me noticed. Any woman who walks any distance at all is automatically regarded as a hooker!

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.

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.

I just wanted to be an actress. It never occurred to me that I could become famous, because I'm not one of those people who's automatically going to be the lead. I always saw myself as the mate.

Mind you, if a blockbuster movie was offered, I wouldn't say no. I can do accents - I don't always have to be Scottish.

I'm thinking of Mary Poppins, The Sound of Music... there are too many to name really. And all the old classic ones like Snow White & The Seven Dwarfs and Bambi. That's brutal!

It was almost like being a child again because you felt like you were in your bedroom and it almost felt like no one was really watching you. So, you were just kind of having a bit of fun on your own doing silly voices in the bedroom.

I know what I look like. I'm not a babe who's automatically going to be the leading-lady type. I think I would always be cast as the friend. I probably tend to look crap more often than I look good. I like messing around and pulling funny faces and doing funny walks.

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.

My mum Margaret was a single parent, but though life was a bit of a struggle she gave me every encouragement.

I always felt slightly grubbier than most American people. I was never quite as groomed as everyone else, never quite as fit as anyone else. I didn't have my protein shake and my vitamins.

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.

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 still giggle when someone asks for my address and I say, Hollywood, Los Angeles.

I think that children that are acting are always pretty savvy anyway because you're conducting yourself around adults a lot of the time, aren't you? But there is this worry now that children just want to be famous.
