Most of the crew were staying in Monaco. But my family and I were actually staying in Nice because I had my whole family there and we wanted a little more space and to stay in a hotel. The truth is we were asleep [when the attack Bastille Day terror happened] and woke up the next morning to it and it was obviously horrific. And then the idea of going out and filming, it just felt so stupid to be working the next day and pretending that everything's cool when you're making some frivolous thing.

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

I am never going to please all 100 million people who read the book. I'll be lucky if half that number are happy with me playing Christian Grey. I know there are campaigns of hate against me already.

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'd known plenty of people who'd worked with Cillian [Murphy], and he was one of those people I'd only heard good things about. It's pleasing when it works like this. As Cillian said, it's not always like that.

Because I used to play a lot of sport, I've always been in decent enough shape. When I used to get asked to do a bit of body work before a photo shoot I'd lie and say, 'Yeah, I'm going to the gym.' I literally never did anything.

I think you only watch stuff you've done once because I don't think it's that beneficial to you. I think it's important to sometimes be like, 'What's that thing I'm doing with my face? I didn't think I was doing that.'
