Here's one from back in the Golden Age of Hollywood: Vivien Leigh was disgusted by the stench wafting from Clark Gable's mouth whenever she had to kiss him in Gone With The Wind. At only 32, a gum infection led to Gable having most of his teeth replaced with dentures, which he must've cleaned with formaldehyde. So next time you're watching Gone With The Wind, which will likely be never, know that whenever Leigh was less than a foot away from the handsome Gable, she would rather have been killed by Union soldiers.

And of course, there's the sub-category of actors who give themselves bad breath on purpose to mess with their costars, like how Liam Hemsworth and Jennifer Lawrence would eat garlic or tuna before onscreen kisses during the filming of the Hunger Games movies, because movie sets are just so much fun, you guys! Actors eat awful stuff to mess with you, and you just have to sit there and keep pretending! So great! Excuse me for a minute, as I have to go vomit on the sidewalk.

John Rhys Davies doesn't have as fond a memory of working on the Lord Of The Rings movies as the rest of the Fellowship. While the others had to wear, at most, a pair of awkward floppy prosthetic feet or fake pointy ears, Davies was in a full facial prosthetic held on with glue he was allergic to. Those movies took around three years to shoot, and Davies was in pain every single day he was on set. Gimli might have been a grumpy character, but the man who played him hated living in Middle-earth more than any crotchety dwarf ever could.

In Legend, Tim Curry played the Lord of Darkness, ostensibly the devil, showcasing one of the most impressive monster makeup effects in movie history. But as you'd suspect after a quick look at him, the huge fiberglass horns on his head messed up his neck and back. One night, while performing his ritual of soaking in a bath for an hour to loosen the prosthetic glue, Curry lost his patience and started ripping off the prosthetics, taking chunks of his own skin with it.

A small price to pay for a highly f**kable devil.

Producers brought in a CIA torture expert to teach Jim Carrey techniques on how to endure the hell of his eight-and-a-half-hour transformation into the Grinch. As if seeing the Grinch in real life wasn't terrifying enough, imagine the Grinch chain-smoking and punching his own legs while demanding that people randomly hit him across the head. He described the makeup application as "being buried alive every day."

We're still waiting to hear about how torturous it was for Mike Myers to sit through the makeup process for The Cat In The Hat. Has anyone heard from Michael? Anyone?

That's pretty much what Henry Cavill did on the set of The Tudors when he got hard during a sex scene. "It's not great when you're in a professional acting environment and somebody gets a boner, is it?" Acting is one of the only professions on Earth in which a boner is not welcomed but is understood, given a specific set of circ*mstances -- that being two people intentionally giving each other blue balls.

While I'd imagine it's a painfully awkward experience for most actors, there is one performer I came across in my research who could probably make the full transition into porn if he wasn't also one of the people whose name continuously came up in my research for actors with bad breath. Hugh Grant once said, "I've always enjoyed sex scenes, though you're not really supposed to. The classic answer is, 'Oh, it's not sexy at all because there are so many technicians standing around.' But I've always found them extremely arousing." A sound guy in cargo shorts and a Chicago Cubs hat looming over Grant with a ten-foot pole as he pretend-plows an actress who'd rather be anywhere else on the face of the Earth than in that room in that moment really gets his balls swelled with anticipation.

Where Grant is living up to his reputation as a man who will f**k anyone, anywhere, anytime, Cavill is echoing a sex scene mantra that male actors from Tom Hanks to Ashton Kutcher to Samuel L. Jackson and possibly even as far back as Sir Laurence Olivier have for years been saying to their partners before cameras roll: "I apologize if I get aroused, and I apologize if I don't."

It's a clever phrase, and it does cover both ends of the spectrum of male insecurity in the midst of a sex scene, but it also assumes that a scene partner will be hurt if the guy they're dry humping in front of a crew that just wants to break for lunch doesn't get aroused on the job. I don't want to speak for the actor being ground with a c**k-socked penis that may or may not be flaccid, but I think they'll somehow find the strength to move on from the pain brought on by the absence of a boner.

Still, the accent's exact origins aren't entirely known. One theory suggests it was developed to better fit the tinny tones of old radios, which couldn't produce bass without blowing out their speakers. While there's no one person or story to point to for its origin, we can point to one group of people for popularizing it: America's aristocratic elite. The accent gained prominence in a time when America was prosperous and the influence of the very rich held sway. That changed after World War II.

The death of Hitler pretty much coincides with the death of the Transatlantic accent. The middle class was growing and American aristocracy was starting to lose its shine. There was a national desire to see common, middle-class speech patterns reflected in movies. The Transatlantic accent, which was very obviously fake, had finally begun to sound fake to people.

The Crow is a movie I watched, I'll say, ten times before learning its star was killed during filming in a freakish gun accident. My 11th and final viewing was spent examining each frame like Kevin Costner looking over the Zapruder Film for evidence of a second shooter in JFK. Turns out the tragic mid-scene death of an actor during the production of a film was not included in the final cut. Seems like a real lost opportunity.

The Twilight Zone movie is probably the most famous example of the bunch. Actor Vic Morrow and two child actors were famously killed during a horrific accident, which was made all the more terrible when it was discovered that director John Landis ran what might be one of the most dangerous, most morally bankrupt movie sets ever.

But none of them trigger my morbid fascination with on-set death quite as thoroughly as The Adventures Of Milo And Otis, the live-action kids movie about a dog and a cat who get into a series of scrapes and have to find their way back home. It's was probably really cute when you were four, but it gets remarkably less cute when you hear that pesky, unproven (but extremely prevalent) rumor that up to 30 Milos and Otises were killed during production, and one kitten may have had its paw purposefully broken for one shot, and oh my god, if that's true, the movie is a cinematic pet cemetery. The rumors were never proven, so we may never know for sure just how many animals may or may not have been killed to make 1986's 14th most forgettable movie.

But here's one unsettling bit of trivia to leave you with: You know how movies with animals in them will say "No animals were harmed during the making of this film?" The Adventures Of Milo And Otis has that, but its wording is a little ... off. It says: "The animals used were filmed under strict supervision with the utmost care for their safety and well-being."

I'm not saying they're lying. What I'm saying is, if you asked me if I killed 30 dogs and cats to make a s**tty kids movie and I didn't want you to know, I think I'd say something along the lines of "Well, we did try our best." And then I'd run as fast as I possibly could away from you. Like, I-just-popped-a-boner-on-set fast.
