I almost never get recognised in the street.

That scene in 'The Purge' where my kids, Mary's kids, are in danger was really crazy for me, because I suddenly I have my methods as an actor, so I went to the place of 'If somebody came near my children, with bad intent?'

I have an internal protectiveness where it's like, if it comes to just me, as frightened as I am of losing someone I love or things going sour or simply being alone, there is a dark place in my brain where I'm like, It could happen and I'm okay, I'm prepared.

There is something in the act of having tattoos done that I love. It can be quite addictive. I've got a few on my back because my friend is an artist, and a few on my arms. Every time I pass a tattoo parlour, I think, 'Maybe just a tiny one.

I'm sort of like a T. rex in the world of female actresses. Every time a job is finished, I look at my car and think, 'Could I live in it?

I love being physical, but I am extreme either way. I can be superfit. And then I can be really lazy and ignore everything.

People do seem to think that I'm going to be some wicked witch, and then they're always surprised to find out I'm just a little clumsy nerd.
