Aubrey Plaza, Dirty Grandpa (2016) “I didn’t know him [Robert De Niro], we had never talked and I was really scared of working with him. So I was like, ‘I’m going to do something kind of crazy.” “I took an incredibly slutty picture of myself in character, put it in a book about Zen Buddhism, and slipped it under his trailer door. I didn’t hear anything about it for a week, so I was terrified that I was going to get fired. Then, he casually came over to me a week later and was like, ‘I got your book…’ — and I had put the photo on page 4, so then he said — ‘I only got to page 4, but it was VERY good.'”

Keanu Reeves, Knock Knock (2015) “I mean, those scenes are always weird. But Eli [Roth, the director] created a great situation of trust in rehearsal…but eventually you’ve got to strip naked and simulate, and I wasn’t going to be that guy who was like, ‘Hey Eli, your wife’s hot!’ Yeah no, he was really cool about it and we all…had fun.”

Margot Robbie, The Wolf of Wall Street (2013) “I got a million paper cuts on my back from all that money. It’s not as glamorous as it sounds. If anyone is ever planning on having sex on top of a pile of cash: don’t. Or maybe real money is a bit softer…when I got up off the bed, I turned around to get my robe and everyone gasped. They said, ‘You look like you’ve been whipped a million times.”

Dave Franco, Neighbors (2014) “I was pretty nervous for the scene. I met [Halston Sage] the day before, and she was beautiful and very sweet, but it’s awkward. You meet each other and then you’re grinding — you don’t even know her name, barely.” “And then, of course, I woke up that morning and I had a giant pimple on my ass. I had to go to the makeup artist who I had ALSO just met that week and be like, ‘Can I go in the other room and have you put makeup [on it]?'”

Olivia Colma, The Favourite (2018) “So…Emma had to finger me. She was a little bit worried, since it was under the sheets. So I went to makeup and I got a sponge…a big, wet sponge. I put it there as a barrier and told her not to worry about it. So when we were shooting, she was going up my leg and then went ‘OH?! [in disgust]’ and I was like “Oh no, it’s a sponge!”

Kristen Wiig, Bridesmaids (2011) “There’s some good positions in there. Jon Hamm — pumpin’ away. He was making his money that day. There was nothing hot about that scene. We weren’t, like, looking into each other’s eyes.”

Jamie Dornan, Fifty Shades Darker (2017) “When there’s a wider shot and we’re going for it all in one piece, they’ll play music over it, and it’s always my temptation to make Dakota laugh. So sometimes, I’ll do things like — in a moment when I’m meant to orgasm — I’ll instead go, ‘Doo-doo-doodley-do!'”

Vanessa Hudgens, Spring Breakers (2012) “It was very nerve-wracking for me. I told my agent I never want to ever do it again. Hallelujah for Ashley, and the fact that it was a pool kind of made it a lot of fun. I was like, ‘Peace out for a second. I’m going to swim around.'”

Mila Kunis, Black Swan (2010) “It’s hard to have a sex scene, period. It doesn’t matter if it’s a friend, a male, a female. You’re with 100-something crew members, lighting you, repositioning you, there’s no comfort whatsoever.”

Ben Affleck, Live By Night (2016) “You do scenes and, sometimes, I like to go over and over again without cutting, because I don’t like to interrupt the flow.” “But we had these montages of sex scenes and — in my mind — I was thinking, Well, we’re just going again, like without yelling ‘cut’; we’ll just keep going. And finally, Sienna just started laughing and said, ‘Who do you think you are? How many times can one man climax?!'”

Julia Roberts, Pretty Woman (1990) “I had never done this kind of stuff before, and I was really nervous. I’d get hives. They’d say, ‘kiss,’ and I’d get a hive…but the funny thing is that we’d become such a family. “ “This particular crew, we became so close to one another that by the time a scene like this came up — everyone knowing the way that I felt and my kind of value ideas about it — everybody was more nervous than I was.”

Ryan Reynolds, The Change-Up (2011) “So in the scene she’s [Oliva Wilde] sitting there, and I take her top off, I take her bra off, and she has those pasties on, but she’s drawn these adorable little smiley faces on them. And I forget every line in the scene. Not just from this movie, from every movie I’ve done.”

Alison Janney, Life During Wartime (2009) “Michael had to push me up against a wall, and they wanted us to look sweaty for the shot. So they sprayed this glistening stuff all over us. They didn’t realize that we’re on a marble floor.” “He pushes me up against the wall and — all of a sudden — we drop out of frame because he slips and he drags me down with him. He falls on his knees and I can’t stop laughing…and the cameraman couldn’t stop either. But [Michael] really hurt his knees. He had to go to the hospital.”

Robert Pattinson, Breaking Dawn Part 1 (2011) “There was TOO MUCH buttcrack. That was one thing I was told they had to cut out, but they didn’t cut the shot — they just cut my crack out. Like, they painted over it, because you can show cheek, but you cannot show crack.”

Mark Wahlberg, Boogie Nights (1997) “The first time they made it [prosthetic penis], they used the exact same specs as John Holmes…a very famous porn star from the ’70s.” “So this thing was down past my knees. Everybody thought it was ridiculous, and I had to come out on the set to show it to everybody. It was very embarrassing, BUT the shorter one they remade is still the only prop I’ve ever kept from a movie.”

Keira Knightley, Atonement (2007) “I probably broke them ALL [green dresses] while shooting the scene. You can’t have a sex scene in a dress like that! It was all laser-cut in the front, so literally if you touched it [it ripped]. They had so many [backups], and the tops had to keep being resewn and redone.”

John Turturro (Director), Romance & Cigarettes (2005) “One time, I directed a sex scene for a movie, and I realized they seemed too inhibited. So I decided to take James out of the scene and I put Kate on a big bouncy ball and just had her bounce and look around.” “The problem was how to connect them so when it was James’ turn, he pretended to have sex and I threw Kate’s wig around…so if you watch the scene, they’re completely free, but they’re not in the same room together.”

Ashton Kutcher, No Strings Attached (2011) “I just start by apologizing … I think somebody told me, and I’m not sure who the actor was… I think he said something to the effect of, ‘I apologize if I get aroused and I apologize if I do not get aroused.’ And you have to say it with the accent if you do it. But there is sort of always this awkward state of, is this OK, is that OK? And then in between it’s like, just, let’s act like nothing happened. And then you see how good of an actor you really are.”
