I don't think [Fifty Shades of Grey is] a model for anything. Except maybe in bed.
Erotica is simply high-class pornography; better produced, better conceived, better executed, better packaged, designed for a better class of consumer.
I think the love scenes are very powerful and they're not trying to simply show the bodies of the actors but trying to reflect the inner feelings of the character so it's easier in that way.
I suspect that one of the reasons we create fiction is to make sex exciting.
If you read my short stories, there's a lot of sex in those in all different ways. To me, it's a really good, useful thing to get to have in a story. And in a movie, it's amazing, because you actually get to show things.
