"Fifty Shades Darker" star Jamie Dornan recently revealed that he went to an S&M school to better prepare for his role as Christian Grey.

In an interview with Shortlist, the actor said that he knew Christian wouldn't be complete without his obsession for BDSM. With this, the actor took it upon himself to learn the jargons and everything related to the practice to give his character justice.

"It's such a big part of the character that I wanted to know what I was doing. This guy came along with his submissive, I sat in the corner with a beer and watched. My driver was on the other side of the door, God knows what he thought," he said.

Meanwhile, Dornan also revealed that he accepted the controversial role because he knew that he will regret not accepting it later on.

In 2014, the trailer for "Fifty Shades of Grey" became the most viewed video on YouTube. The film itself also became a massive hit across the globe. Even though the film received a slew of criticisms, fans continued to watch it, and most people got hooked with how Dornan portrayed his character.

In other news, Dornan also revealed that he doesn't have any vices. In fact, he's only obsessed with eating crisps. The other things that he loves doing are spending time with his wife Amelia Warner and daughter Dulcie.

"My only vice is crisps, but I can get away with that. I've never really found myself out of shape," he said.

While speaking with Glamour UK, Dornan also gushed over his wife and said that she's the most understanding person he's ever met. As of late, it is unclear whether or not Warner is pregnant with their second child.

"Fifty Shades Darker" will premiere on Feb. 10, 2017.
