The actress opened up about their intense day of filming
Sienna Miller was left shaking 'in tears' after filming with Ben Affleck for multiple s-x scenes went on for nine whole hours.
The actress, who stars alongside Affleck in his new self-penned 1920s drama Live By Night, opened up about the intense day of shooting for Ben's film, which features her as an Irish femme fatale named Emma Gould.
Speaking to E! about the s-x scenes, Sienna said the co-stars found filming "hysterical" – leading to her having to leave the set with tears running down her face.
"Ben and I are like brother and sister, thank God, so there was no awkwardness. There was just a lot of stupid giggling. He's very professional—I am not, but he is," she revealed.
"There was a montage in the script saying we did it everywhere: in the car, in the bar...I was like, 'That's an entire day of just love scenes! OK. How do we do this?'
"Obviously, by the time nine hours of it has gone past, I was shaking with tears running down my face. I mean, I can't tell you – but you have to laugh. Ben is just professional. It is what it is."

When Ben – who was also directing at the same time as starring – told crew to keep the cameras rolling throughout their racy scenes, Sienna couldn't hold it together any longer.
"This happened three times, and by the third I [finally said], 'Are you joking?'" Sienna went on.
"And then I was like, 'I don't know what you're trying to tell people, Ben, about your s-xual prowess – your abilities.'"
It turned out to be just so Ben had plenty of takes to use in his final edit, but Sienna hadn't been warned they'd film continuously – which prompted yet more laughter.
"There will be some outtakes from that where I have to walk out of the room because I just have tears running down my face," the 35-year-old added.
Meanwhile, Sienna experienced being star-struck at the weekend when she found herself backstage in a huddle with Ben, Brad Pitt and Jon Hamm, which she described as "surreal".
"It was exciting. I have a mental photo that I will hold onto," she added.
