Sienna Miller has revealed that during filming sex scenes with Ben Affleck she was "shaking with tears running down [her] face".
The pair star together in a new film called Live By Night, which Ben acts in and directs.
Sienna spoke about a day where they had to shoot sex scenes for 9 hours, "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?'"

She continued to tell E! News, "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.
"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."
