It was fine when I was single and childless. Carrying the responsibility of screwing up your kids at the same time is huge. I remember when I got Peter Pan, and I told my mom and dad and my friends I was leaving - again, I was cast way late on - in the next two days to go to Australia for four months, and they all went "Bye! See you in four months!" But no one said "We need you," and I really knew that it was time to think about someone else for a change.

My agents were like "Come to L.A., we've got meetings for you." I was like "No, I'm doing this now." Then my father became very ill back in England, and I didn't want to be away. I went back to England and did a bunch of crazy indie movies, all of which I loved with a passion, and none of which did any business.

The trouble with audition process is, when you're an unemployed actor, it's the only time you get to act, and it can be quite fun. If you feel in control of the material and you feel that the people are pleased to see you and are excited by you auditioning for them, it can be a really rewarding process. But it can also be a very humiliating process.

There are movies where I've walked onto the set and felt, "This is home," and I'm confident in myself and my work, but that was my first experience of live TV. At that stage, Friends was at its unassailable height of popularity and brilliance.

The way I miss my daughter Esme is to worry about her. It is not a pleasurable longing. It contorts my body and scrambles my brain, makes me stop breathing, clench my jaw and my fists, it makes me frown, and makes me blind and deaf, in fact entirely without sensory perception.

My parents taught me everything and set me up for life. I owe to them all the things I'm passionate about: music, art, the people I love, my career and family life, the fact that I have children and the way that I raise them.

The excruciating moments of drama are when people are allowed to show or say what they feel.
