I'm probably the worst person for 'Men's Health' to interview.

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.

You're in a very nice position as an actor when you're portraying a piece of history that actually happened and portraying characters that actually existed. There's so much more to draw on and your research as an actor becomes much easier than if it's some fiction that you're trying to create a world around and background and history.

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.

You want roles that challenge you and that scare you a little and where you can really discover something, even about yourself, that maybe you didn't understand.

I was and still am a massive fan of [Murphy] Cillian's work - always have been. Obviously he's a great deal older than me, so I've sort of grew up watching Cillian's work. But I'm very much a fan.
