5 Famous Movies That Used Horrifying Substances for Effects

What that screencap isn't showing you is Henriksen's character, Bishop, dramatically coughing that stuff up everywhere in the first place. Yep, he had to chug rotten dairy products and regurgitate them back onto himself like a pornographic Exorcist.

Of course, it didn't start off spoiled. The problem was that the special effects team didn't remember to put the milk and yogurt smoothie back in the fridge after they whipped it up. They just left it out overnight -- and it also sat under those hot lights between the long, long takes ...

If Henriksen's performance seems genuinely pained in his final scenes, it's not just acting: after the scene wrapped, Henriksen says, he was "sick as a dog" and spent the next four days puking. And it wasn't just because of that disturbing alien queen egg-chute scene ...

The Terrible Reality

Sometimes being Matt Damon means wading through a sea of garbage, and we're not just talking about The Adjustment Bureau. Blomkamp filmed large parts of Elysium in Mexico City's Bordo Poniente, the world's second-largest dump. The landfill covers 975 acres and holds 76 million tons of trash.

The fear of illness was very real: Damon had to discard his clothes at the end of every shooting day. Here's one location that the cast and crew affectionately nicknamed "Poo River."

So, if you're watching Damon and Sharlto Copley battle it out in that apocalyptic wasteland, remember that the dust blowing around their faces and probably into their lungs is "mostly fecal matter." The crew was lucky enough to be given masks, but obviously the actors had to go without and risk a case of the ol' poop lung.

And this isn't "gourmet chocolate bar with caramelized bacon" or "liver with a cocoa powder reduction." This was cheap, room temperature roast ham, pig intestines, and Bosco.

Using pork as a replacement for human flesh is a trick that zombie filmmakers use to this day, notably in The Walking Dead, but the cast of that show are given the more palatable option of barbecued pork covered with food coloring instead of chocolate. Though some particularly hardcore actors will tear apart raw chicken with their teeth for added realism. No matter what Shane may have said about Rick, at least the guy playing him seems like he has the balls to survive the zombie apocalypse.

Les Miserables is about a bunch of people who suffer horribly for trying to do the right thing (there's a reason it's not called Les Happy Fun Times). And none of the characters suffer as much as Fantine, a young woman trying to support her daughter who loses her job for spurning her boss' advances, sells her hair and teeth, and ultimately goes full prostitute. Then she dies of tuberculosis. Then she probably goes to Hell. Like, the ghetto of Hell. And in the 2012 film, the set designers wanted to make sure the actors had every bit as bad a time as the audience.

The Terrible Reality

According to production designer Eve Stewart, they brought in real seaweed and barrels of decomposing fish to decorate the set, which slowly turned rank under the studio lights. Rotting seafood really helps contribute to that 19th-century seaside prostitute vibe. To make matters worse, this is the same set where Anne Hathaway, who plays Fantine, recorded the four-minute, single-shot take of "I Dreamed a Dream," which took eight hours to film.

And yet the version of the song used in the movie was nailed on the fourth take, which was shot in only 20 minutes. But Hathaway insisted that she could do it even better and went on to try again and again and again for another seven and a half hours, during which time she and the rest of the cast and crew stewed in an aerosolized brine of rotting fish.

For a shot, you'll note, that could've easily been filmed literally anywhere else.

There's suffering for your art, and then there's making sure everybody else suffers for your art. We're guessing the crew made fun of Hathaway's haircut or something, and she's just really, really good at revenge.

Before CGI, studios needed to come up with a convincing practical effects method for faking snow, just in case the producer couldn't control the weather with sheer willpower and contempt. The most common trick was to blow wispy little cotton balls around. It worked pretty well, but it was missing a certain je ne sais quoi (that's French for "air poison").

The Terrible Reality

When a firefighter pointed out that cotton is incredibly flammable, the filmmakers behind The Wizard of Oz made a bold decision in the name of health and safety: they swapped out cotton for asbestos. The on-set OHS officers promptly died of irony poisoning.

That scene in which Glinda the Good Witch sends a gentle snowstorm to wake Dorothy from the magic poppy fields? Yeah, she was actually blowing bucketloads of deadly, cancerous asbestos right in Dorothy's face. Maybe her name is supposed to be ironic, like calling a big man tiny.

To be fair, the dangers of asbestos weren't very well known back then; we were just a few decades removed from using heroin and radium as a delicious snack for the kids. Also, white chrysotile asbestos -- the kind they bathed Dorothy in -- is less lethal than other types, though that's a bit like saying it's safer to fight Mike Tyson than a polar bear. Experts consider it extremely unwise to fuck around with either.

Judy Garland and pals frolicked through 27 asbestos blizzards before they got the footage they needed, as the actors who kept screwing up their lines had no idea that each stutter was taking a month off their lives. It wasn't just a fluke for The Wizard of Oz, either. Bing Crosby's Christmas movie Holiday Inn had both stars literally buried in potential cancer.

The golden age of deadly snow ended with World War II, when America's asbestos stash was redirected for military efforts, forcing Hollywood to develop saner alternatives. But years later, people still bought chrysotile snow products to decorate their Christmas trees at home. So if you ever find packets of stuff called "Pure White" or "White Magic" or "Snow Drift" up in grandma's attic, keep in mind that it isn't leftover medicinal cocaine from the good ol' days.
