I’d been auditioning for parts for years, I never got any better at it. I’m crap at auditions.

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

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.

I know because the movie's made a lot of money, everyone's relaxed a bit so there wasn't that pressure to set the tone for the movies [Fifty Shades of Grey] so I felt a little more freedom this time and it probably made it more enjoyable.

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.

It's a tiny industry. Actors all know each other to a point where you always know someone who knows the other person who worked with them.

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.
