Jamie Foley - he's a very different energy to [director] Sam [Taylor-Johnson]. The whole experience was actually quite different.

There's very exciting directors who haven't made a feature yet. That's what's cool about the job - the ever-changing landscape of people you could potentially work with.

I guess I'm just lucky with my genes.

I don't have specific people. There are so many people that I admire and there's directors that I'm desperate to work with that haven't even made a movie yet, probably.

I’m not saying we had a playroom, but I’m not shocked by the sex in the book. It’s essential to tell the story. I can’t believe films that don’t invoke a sexual side of it. So it works for me.

I can't really do the running on hard ground that I used to do. Instead I go swimming as often as possible.

I think you've really got to cling to what makes sense to you. Obviously, I'm not a serial murderer in my real life, so that's where you have to delve into and do all the research. But, you have to find something likable in the character.
