I remember I did think, 'Wouldn't it be nice if Mr Right moved in next door?'

I was reading William Shawcross's biography of the Queen Mother, dressed in my witch outfit! And you know what? It was a really good mix; it was a therapeutic mix.

People have lots of misconceptions about me. My mum, who is half French and half Spanish, gets outraged when I'm called quintessentially English. I owe my looks to my mum-which was 90 percent of getting my first job. And, some people would argue, 90 percent of my entire career.

Usually I'm frustrated when I look at my films and I don't believe that I've made a real transformation beyond my usual sets of gestures and expressions. I still have this nagging feeling that it's me, that I didn't create a unique character.

It was a challenge to be able to create a character without being able to use one's normal set of expressions. All the rubber and makeup attached to your face left you with only a modest range of facial movements.

I love changing what I look like because I always feel super strange whenever I do watch something that I'm in.

People say, "You're still breast-feeding, that's so generous". Generous, no! It gives me boobs and it takes my thighs away! It's sort of like natural liposuction. I'd carry on breast-feeding for the rest of my life if I could.
