I don't like my physique. Who does? I was a skinny guy growing up, and I still feel like that same skinny kid.

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.'

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.

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

That tag - underwear model - I just can't get rid of it. And it's such a bizarre, specific thing - underwear. It's like I never modelled clothes.

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.

It's not like I cleaned up with girls. I always looked young and I was very small; I hated being 'cute.'
