— -- We are just about two months away from the premiere of "Fifty Shades of Grey" the movie and the film's star Jamie Dornan is opening up on how he prepped for the big role as Christian Grey.

In fact, he literally went to a sex dungeon in someone's home. He only observed.

“I went there, he offered me a beer, and they did ... whatever they were into," he told Elle UK for its February issue. "I saw a dominant with two submissives, and he became our kink advisor on the film.”

The experience shocked the 32-year-old actor.

“Then going back to my wife and newborn baby afterwards," he continued. "I had a long shower before touching either of them.”

The February issue of Elle UK hits newsstands on Jan. 2.

"Fifty Shades of Grey" hits theaters on Valentine's Day, 2015.
