The GLARING Error in ‘The Wizard of Oz’ That Filmmakers Hoped You Wouldn’t Notice

Wizard of Oz munchkins have a dark backstory: Many of the actors who played Munchkins had fled to the U.S. from Germany to escape the Nazis. Because most did not speak English, the majority of their voices are dubbed in the film.

The Wizard of Oz poppy scene is famous, but it also hides a movie-making secret that would never pass muster today. In the scene, Dorothy and the Cowardly Lion fall asleep in a poppy field, where it begins to snow. The "snow" used was actually potent chrysotile asbestos, despite its known health hazards. Yikes!

Wizard of Oz Munchkins were not treated very well. Though it's partly a sign of the times, the actors who played the Munchkins were paid just $50 a week for a six-day work week, according to one actor, Jerry Maren. Meanwhile, the cute dog playing Toto was paid $125 per week!

Judy Garland's hair in The Wizard of Oz is a bit peculiar. If you look closely, you will notice that her character Dorothy's hair changes length during the film. At one point you see her hair is just at her collarbone, but by the end of the film it's down to her chest.

Remember the purple horse from The Wizard of Oz change colors right before our eyes? Movie-making history was forever made when the film's production team used Jell-O to tint the horse's ever-changing colorful coat. The colored horses in Wizard of Oz shouldn't worry animal lovers: Producers consulted the ASPCA, and the method was totally safe for the animals.

Lion from Wizard of Oz is a beloved brave character, even if the poor actor playing him might not have been feeling completely like a "king" the entire time. See, the Wizard of Oz Cowardly Lion’s costume was made of a real lion skin, which made it incredibly hot for actor Bert Lahr to wear. It was also HEAVY — it weighed nearly 100 pounds!

The Wizard of Oz twister scene wasn't actually a real twister — no shocker there, right? But the method for achieving the famous tornado is pretty inventive. To create the same effect of a Kansas twister in a safer way, a 35-foot muslin stocking was used and swirled with dirt and dust.

Wizard of Oz dog Toto is one of the most famous canines of them all. Did you know she was played by a girl dog? Sadly, the dog playing Toto was stepped on during shooting, and had to be replaced with a doggy double for two weeks of filming while she recovered from her injuries. (Her real name is Terry!)

Wizard of Oz munchkin hanging rumors — who hasn't heard them? Here's the truth: The famous story that a swinging shadow in the background of one scene was really an actor committing suicide is false. According to MGM, the shadow was just a large bird stretching its wings. Time to put the Wizard of Oz hanging story to rest, once and for all.

The Wizard of Oz Dorothy dress — has there ever been a more famous movie garment? But here's a strange secret: Judy Garland wore a tight corset under her dress in order to help make her figure look more childlike as Dorothy. In real life, she was 16 years old during the making of the movie. (If you're making a Wizard of Oz Dorothy Halloween costume, we highly recommend leaving out the corset.)

Another Wizard of Oz Dorothy dress secret: The white in the memorable dress worn by Dorothy was actually pale pink, because pink showed up better as white in Technicolor. So odd!

The Wizard of Oz witch was quite the villain, but no wonder she was cranky! Margaret Hamilton, who played the Wicked Witch of the West, wore copper-based bright green makeup that was dangerous to ingest, so she didn't eat food during filming! She was only allowed to consume liquids. Imagine? That's quite the movie diet!

The Wizard of Oz witch makeup didn't just prevent Hamilton from eating. Although she continued wearing it, the same green makeup caused Hamilton severe skin burns during a botched take of a scene where she leaves Munchkinland in a blast of smoke and fire. So dangerous — and thankfully Hollywood pays a lot more attention to actors' safety these days.

The Tin Man and Scarecrow also got hurt, so the Witch wasn't alone in her suffering. The Wizard of Oz Tin Man’s aluminum-based makeup caused an infection in actor Jack Haley's eyes, and Scarecrow actor Ray Bolger's face was permanently scarred from wearing prosthetics, like his fake nose. Pretty horrible, right?

In Wizard of Oz, Judy Garland was intentionally hit in the face! While filming the scene when Dorothy slaps the Lion, Garland couldn't stop giggling — so director Victor Fleming took her aside and slapped HER, after which she nailed the scene in one take. Guess those tears were real!

Tin Man, chocolate — what do the two have in common? Well, when the Tin Man cried in Wizard of Oz, his "tears" were actually made from chocolate sauce, which looked more like water and showed up better on his aluminum makeup. Neat!

The Wizard of Oz "Over the Rainbow" sing is probably its most famous tune, but it almost wasn;t the case: One of the beloved film's most iconic songs was almost cut from the movie! Producers thought "Over the Rainbow" was too long--and too slow--for younger audiences. We're so glad they changed their minds.

In Wizard of Oz, the Land of Oz is a magical place. But ever wonder where the name for the Land of Oz comes from? L. Frank Baum, who wrote the original book, invented the name "Oz" when looking at an alphabetical filing cabinet label, "O-Z." Crazy, but true! Imagine he glanced over at the "A-J" box instead? The Wizard of Aj just doesn't have the same ring!
