I'm keen to have balance, as much as possible. I put every ounce of myself into my work, but also it's important that I don't miss every single wedding of my best friends. I couldn't do what I do without my friends and family.

I'm small. I'm petite. But I'm a bit of a fighter inside. In my work I fight for, I hope, showing women in a true way. They've got brains.

"The Invisible Woman" was about trying to show this conflict in [Nelly Ternan] woman truthfully, between her own identity, but also being in love with someone who I think made very high demands from her.

I always hope for roles that have some depth and that I can get my teeth into and that will challenge me, in some way.

My mother was in advertising and worked incredibly hard when she was bringing us up. She was a working mother and a working single parent. That instills in you a sense of determination.

I think Nelly [Ternan] actually has something very conservative about her, and she's very judgmental of (this other character's) situation, and can see that's about to happen to herself. So she judges it even more harshly [because] it's what she fears becoming.

It was amazing how much rehearsal helped with the performance - it was almost a theatrical approach to filmmaking.
