Actors can wind up in some uncomfortable — and even downright disgusting — situations for their jobs. Here are some celebs who have opened up about some really gross things they had to do while filming...

For Elf, Will Ferrell had to eat spaghetti covered in candy and syrup. "I ingested a lot of sugar in this movie and I didn’t get a lot of sleep. I constantly stayed up," he said. "But anything for the movie, I’m there."

New Line

While playing Katniss in The Hunger Games: Catching Fire, Jennifer Lawrence had to eat a raw fish — and "not like a sushi raw fish," she said. "I held a fish and had to eat it. And for the record, it tastes exactly how it smells...I don't like fish."

Summit

While she didn't have to eat it, Anne Hathaway said being surrounded by dead fish to film scenes for Les Misérables was a struggle, especially because she had just become vegan. "For some reason, for the dock scenes, [director Tom Hooper] wanted us to have dead fish, for days, and days and days on end...there I am in period-looking pleather shoes, stepping on dead fish, and I was having a real crisis of conscience."

Universal

In Vampire's Kiss, Nicolas Cage had to eat real, live cockroaches, in part because "the thing I hate most in the world are cockroaches," he said. While he was keen to create an unforgettable cinematic moment, he later revealed, "I’ll never do that again. I’m sorry I did it at all."

Herndale Film Corporation

For the movie Spawn, John Leguizamo had to film a scene in which his character Clown eats a maggot-covered pizza. John insisted they use real maggots because otherwise it wouldn't have the "same effect." He later said, "it was disgusting and I only did one take."

New Line

Nicole Kidman actually peed on Zac Efron for a scene in The Paperboy in which his character is stung by a jellyfish. When director Lee Daniels hesitated putting the shot in the final film because it might be too "vulgar," Nicole told him, "You made me pee on Zac Efron. If you don’t put it in the movie, you need to man up."

Lee Daniels Entertainment

In Poltergeist, JoBeth Williams has a scene in which her character Diane falls into water that's full of skeletons. JoBeth thought they were made by the prop department, but she discovered years later that they were actually real skeletons. "I don’t know where they were bought from, but that really grossed me out," she said. "I’m glad I didn’t know that then, because I would’ve really been screaming a lot — for real."

Warner Bros

While playing Catwoman in Batman Returns, Michelle Pfeiffer did a scene in which she held a real, live bird in her mouth. "I look back and say, 'What was I thinking?' I could've gotten a disease or something from having a live bird in my mouth," she said.

Warner Bros

Over the course of You, Penn Badgley had to do a lot of creepy and gross things in character as Joe — but he said the many masturbation scenes were some of the hardest to film. "I've now done it so many times on camera," he said. "It's a strange — you don't think it's going to be that big of a deal. And then you discover in front of a crew of people with a camera in your face, knowing that, in all likelihood, millions of people are going to see this, you're simulating masturbation." He added, "I have to say sometimes those scenes are harder than with a person because it’s just like, 'Alright, this is what I’m doing...I've always gotten the note to make it less creepy."

To film the first cannibalism scene in Yellowjackets, the crew made a fake dead body with rice paper and jackfruit. Star Sophie Nélisse said it was "soggy" and gross, even causing several cast-members to heave and one to actually vomit. "We were like, ‘This is the grossest thing ever,'" Sophie said. "It just tasted disgusting."

While filming a scene for Quentin Tarantino's Django Unchained, which also starred Jamie Foxx, Leonardo DiCaprio got so worked up in character that he accidentally smashed a glass and sliced his hand open — but he rolled with it and incorporated it into the scene. "My hand started really pouring blood all over the table," he later said. "Maybe they thought it was done with special effects. I wanted to keep going. It was more interesting to watch Quentin’s and Jamie’s reaction off-camera than to look at my hand...I’m glad Quentin kept it in."

Still on Leo, he said some of the scenes he shot for The Revenant were actually "some of the more difficult things I’ve ever had to do in my entire career" — including plunging into frozen rivers, performing in real animal carcasses, and eating raw bison liver. "When you see the movie, you’ll see my reaction," Leo said of fil
