1. Margot Robbie was scratched on the back while filming a sex scene over a fake money for "The Wolf of Wall Street."

?I was very scratched at the expense of banknotes. It's not as glamorous as it looks, ?Robbie said. ?If you plan to have sex over money, don't. Maybe the real banknotes are softer. When I got up from the bed, I went back to pick up the detainee and everyone was shocked. They said I looked like they had beaten me. "

2. Aubrey Plaza wanted to break the ice before filming the sex scene with Robert DeNiro in "Dirty Grandpa," so he inserted a "nude photo of himself" into a book and gifted the book.

?I didn't know, we had never talked to each other and it scared me a little. So I thought I'd go crazy, "said Plaza. ?I took a sex photo, put it in a book on Buddhism and left it in the trailer. I was afraid I would be fired. A week later, he comes to talk to me and says, 'thank you for the book ... - I put the photo on the fourth page -' I read it to the fourth page, it was very beautiful. '"

3. Jamie Dornan made funny noises instead of pretending to be orgasming to make Dakota Johnson laugh as he filmed the intense scenes of "Fifty Shades Darker."

"When it's a big plan and we have to do the whole scene from start to finish, they put music in the background, and I'm always tempted to make Dakota laugh," Dornan said. "Sometimes when I have to go into orgasm, I say 'Doo-doo-doodley-do!'"

4. Julia Robert was as embarrassed about the sex scenes in Pretty Woman as she was blushing.

"I had never done anything of this nature before and I was very nervous," Roberts said. "I blush. We were told to 'kiss' and blush it all. We were made as one family, all in exhaustion. Everyone knew how I felt during these scenes and they were more embarrassed than I was. "

5. The first false penis performed for Mark Wahlberg's character in "Boogie Nights" was extremely long, so they were forced to make a second.

"The first one was based on John Holmes, a very famous pornstar in the 1970s," said Wahlberg. ?It was so long, you got on your knees. Everyone seemed funny. I had to go out with him to tell people. It was very embarrassing. The short ones they did later, I kept to myself. It's the only prop I ever kept from an elephant. ?

6. Keira Knightley tore some green dresses during the sex scene in the library at Atonement.

"I'm sure I tore them all down," Knightley said. ?You can't have a sex scene with a dress like that. It was sewn very thin from the front and if you touched it, it tore. They had many versions of the same dress and even some of them patched. ?

7. Ben Affleck attempted to direct and act on a sex scene in "Live By Night" without cutting it, which confused Sienna Miller.

"I do some scenes from start to finish sometimes without stopping because I don't want to break the rhythm," Affleck said. "We had a montage of sex scenes and in my mind, I said, 'OK, we're doing it and once without saying a stop, we just go on.' Finally, Sienna laughs and says to me, 'Who do you remember you are? How many times do you think you can break down? '?

8. Olivia Colman scared Emma Stone with a wet sponge during the sex scene in "The Favorite."

?Emma had to put my fingers in it. He was a little worried, as everything was under the sheet, ?Colman said. ?I went to the makeup room, took a big, wet sponge and put it down there as a barrier. I told Emma not to worry. When shooting, she raises her hand up and says 'OH!' disgusted. 'It's a sponge!' I told him. "
