Northern Irish actor Jamie Dornan visited a sex dungeon to prepare for his saucy role in the new Fifty Shades Of Grey movie.

The Fall star plays businessman Christian Grey in the film adaptation of E. L. James' erotic novel, and he got into character by watching a real life S&M session.

He tells Elle magazine, "I went there, they offered me a beer, and they did...whatever they were into. I saw a dominant with one of his two submissives, and he became our kink adviser on the film... I was like: 'Come on guys I know I'm not paying for this but I am expecting a show.' It was an interesting evening. Then going back to my wife and newborn baby afterwards... I had a long shower before touching either of them."
