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.

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

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.

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 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.

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

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.

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

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.

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'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!

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.

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!

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'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.
