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.

Mass appreciation doesnt always equate to something good.

I'm not afraid to play the role of Christian Grey. Because I'm not like him. But I perfectly understand him. I never thought that he was a monster. He is simply woven from desires. As every one of us.

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.

It's funny when you know you're playing two characters and you're aware of how you have to play each one into your performance of the other. You're constantly at the back of your mind thinking and it all gets a bit confusing.

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.

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.
