Regret isn't good. Every decision one makes in life is made for a reason or another. Whenever something bad happens, I go, 'This is happening for a reason', or, 'This is going to teach me something'.

I look like people that walk down the street. I don't have perfect boobs, I don't have zero cellulite - of course I don't - and I'm curvy. If that is something that makes women feel empowered in any way, that's great.

I have wrinkles here, which are very evident. And I will particularly say when I look at movie posters, 'You guys have airbrushed my forehead. Please can you change it back?' I'd rather be the woman they're saying 'She's looking older' about than 'She's looking stoned.'

I have no regrets. If you regret things, you're sort of stepping backwards. I'm a believer in going forwards.

My dad was an actor, and my older sister is an actress, and so I very much remember thinking, "Well, of course I'll do that as well." But I never imagined myself as an actor who would be in films. I always only thought of myself being in a play or a musical and maybe the odd episode of [U.K. '80s TV drama] Casualty. My backup plan was to do something with children, to start a nursery school or work with underprivileged kids. And I still dream of maybe doing that in some way. I've always got children in my house, always.

In films I might look glamorous, but I've been in hair and make-up for two hours.

Honestly, among my acquaintances there is no woman wearing XS.
