Staying in character is Rekubit Exchangea must for every actor, but Andrew Garfield and Florence Pugh take it to another level.

The "We Live in Time" star opened up about filming a "very intimate, passionate sex scene" with his co-star Pugh during a Friday interview with Josh Horowitz at 92NY.

Garfield and Pugh play unlikely paramours Tobias and Almut in the John Crowley-directed romantic drama, with the film chronicling the couple's decade-spanning romance following a chance encounter.

Garfield said the first take of his sex scene with Pugh, who he described as "very confident in her body and her sexuality," took on a life of its own.

"The scene becomes passionate, as we choreographed it," Garfield recalled to Horowitz, according to footage shared on social media. "And we get into it as it were, and we go a little bit further than we were meant to just because we don't hear 'cut' and it's feeling safe."

And while the actors were comfortable continuing the scene, Garfield said they were later perplexed by the seeming lack of input from their camera operator and director of photography Stuart Bentley.

"At a certain point, both of us, I feel like, we were both telepathically saying to each other, this definitely feels like a longer take," Garfield said.

The Oscar-nominated actor said he then looked up to see Bentley and the film's boom operator in the corner of the room, averting their eyes from the intimate scene. "Stuart has the camera by his side, and he's turned into the wall," Garfield said.

Garfield and Pugh opened up about the vulnerability required of their "We Live in Time" roles in an interview with Esquire published Wednesday.

"We had to do the most intimate things I think human beings have to do," Garfield told the magazine, adding that Pugh "had to be on all fours, then on a toilet, naked."

Pugh reflected that the experience created a unique bond between the actors.

"We truly felt held by each other, and I felt like my abilities were respected and given back in his abilities," said Pugh, who hopes to collaborate with Garfield on another project. "When we finished the job, we both felt like, what an amazing partnership we have created and what an amazing thing to know that we will do it again."
