Actor Jamie Dornan revealed that he visited a sex dungeon in order to prepare for his role in the erotic film, "Fifty Shades of Grey."

The 32-year-old actor told ELLE UK, per Gossip Center, that he needed to understand the whole culture of BDSM.

"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," he said. "I was like, 'Come on guys I know I'm not paying for this but I am expecting a show.'"

"I went back to my wife and newborn baby afterwards... I had a long shower before touching either of them," said "Fifty Shades of Grey" cast Jamie Dornan.

The "Fifty Shades of Grey" film has become one of the most anticipated movies for 2015. It's also the most scrutinized as various speculations and theories were posted on the Internet, particularly on whether it will follow the steamy scenes described in the book.

But in an interview with GQ magazine, he said: "They can't alienate an audience. You know it has to be watchable. It can't be hardcore. I wouldn't have signed up to it if it was. You've got to make something a large amount of people can go and see. It's not going to be grotesque."

"Fifty Shades of Grey" cast Jamie Dornan said the producers are not striving for an R rating in order to expand their target audience some more.

Rita Ora, who plays Mia Grey, meanwhile promised that the "awesome" film will make a lot of waves when it hits the theaters.

"Fifty Shades of Grey" cast Jamie Dornan also said that he's not going to please everyone with his portrayal of Christian Grey considering that there were 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," he said.
