I’m not saying we had a playroom, but I’m not shocked by the sex in the book. It’s essential to tell the story. I can’t believe films that don’t invoke a sexual side of it. So it works for me.

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.

Mass appreciation doesnt always equate to something good.

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've always needed to bulk up, so until the modeling took off I was ramming Big Macs down my throat and doing plenty of bodyweight work. I'm over the Big Macs now, but I'll still drop down and do my press ups whenever I find the time.

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 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.
