I got my first part in Silent Fall, 1994 - I guess I was 15 or 16 - which was really outrageous because I still knew nothing. I don't think I really learned how to land on my marks until after Empire Records in 1995, 'cause sometimes I'll see a shot in that film, and I'm like "Whoa, I just walked over to the corner."

We put so much pressure on ourselves as parents to be able to do everything, but children are very grateful and understanding. I always find that quality time, even if you just get a little bit, really has a deep impact. But you also need them to know that they can make mistakes, and if they do make a mistake it's OK for them to tell you and that they'll get a second chance.

Working with Bernardo Bertolucci, director of Stealing Beauty was my first experience of being able to communicate with someone whom I'd think of as a mentor, who'd ask me my opinion and trust me, and believe in me and allow me to do the things that I wanted to do. The film itself was also rare in terms of character most of the scripts I've read are the story of some man, and there might be a love interest or a big woman's part.

Children are all unique, so when you're blending families it's really important to get to know each individual child... Being a stepparent can be a really incredible opportunity. Sometimes children pay attention and listen to someone who's not their blood parent. Sometimes I notice how my son Milo learns things from my best friends and people that have been around him, his grandparents and so on, in a way he can't from his own mum and dad. It takes a village!

I would rather share one lifetime with you than face all the ages of this world alone.

I feel so blessed that I have a job where I can spend long periods of time with my family. Most moms don't have that choice. But wearing so many hats - mother, wife, actress - does take hard work; you always have to be thinking about your family's best interests.

Beauty is not defined by the size of your jeans.
