Very early on, you figure out that you put your self esteem in the hands of strangers. There's a different commodity. There's the Helena Bonham Carter that everyone thinks they know, who really has nothing to do with me. But you just have to let that go.

I love movies where people see the world from a different angle.

But it's often been the case, I've done so many countless small, independent films that really 3.2 people have seen, so you never know. You do it for the joy of the part and not necessarily expect anyone to see the final product.

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.

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.

And trust. It takes a long time to trust someone. You work with people, anybody you dont know, it takes about a films length to get to know each other. Then if you move on, you have to start right back at the beginning. But if you carry on together and try doing different things, you can all grow together.

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.
