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.

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!

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 do quite like sightseeing. I like churches, museums, galleries and all that stuff. I love the smell of a church in Italy or the smell of an old greasy spoon somewhere. I like markets and little funny shops in the backstreets of Florence.

I wanted to live where I could pop to the bar that Humphrey Bogart took Lauren Bacall to, or the little restaurant where Charlie Chaplin had a booth.

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.
