People say to me, 'Oh, being a mother must make you a better actor,' and I think, 'Well, I never sleep, I have very little time to think about anything except when I'm actually there.' I wonder whether that makes me a better actor. I think it must on some level.

A lot of cop shows, because they have the restraints of having a new case every episode, the victims often become these kind of nameless, faceless plot points, and as an audience we don't feel anything for those people.

I think that's what makes David Ayer really interesting. He likes to make a tough-y movie, but actually he's a character director. He's fascinated by the actual people who decide to have these jobs and the way it affects their lives.

Every role that you play comes with its own set of challenges.

When actors are the real deal, all that star whatever goes right out the window and you're there to tell a story.

The truth is I quite like to dress in jeans and a woolly jumper.

The way that being on the job works on your adrenaline highs and the crashes that come after the adrenaline highs. It really takes over your life.
