"Fifty Shades Darker" star Jamie Dornan recently talked about the most challenging scenes he's ever filmed for "Fifty Shades of Grey."

In an interview with TIME, the actor surprisingly said that he didn't have a hard time going all out with his co-star Dakota Johnson.

Rather, the actor said that filming Christian Grey's interview scene with Anastasia Steele was most difficult for him.

"Anyone will tell you that sex scenes, regardless of the content of the film, are always a tricky experience and relatively uncomfortable. But I guess the scene that had for me personally the most pressure on it, was the interview scene," he said.

According to the Irish actor, this particular scene was most difficult because it's the first scene where fans saw Christian.

"It's the first time we see Christian, and we see him in his highly impressive office, very much in charge and in a position of power. And all of that has to come across, but also have to quickly feel the connection between the two right away," he said.

Meanwhile, Dornan revealed that he and his co-star Dakota Johnson only had two days to perfect their first scene together.

"Which means that I wasn't the only one thinking that we really needed to get it right," he said.

In other news, Johnson said that filming the sex scenes was most taxing for her not because of its sensitive nature, but because it was emotionally taxing.

Still, she and Dornan decided to give it their all.

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