The Mandela Effect has been confounding believers and annoying skeptics for years. This phenomenon is often likened to group misremembering. It’s the idea that so many people could have the same erroneous memory, which feels most unsettling. The original name of this effect is based on the vivid recollections that many have of Nelson Mandela dying in prison, long before he was released. Ask believers, and they will tell you these memory changes are related to the CERN particle collider ripping holes in reality and drifting us through timelines. Ask non-believers, and they'll tell you that human memory is just whacked.

Some of the most common Mandela Effects can be tied to films. In many cases, it could simply be an issue of changing words to accommodate the quotability. Others, however, feel a bit more complex. For any fans of the following films, these real versus mistaken realities are enough to send anyone down a YouTube Rabbit Hole. Enjoy. These are the 15 most baffling movie Mandela Effects, explained.

15 Humphry Bogart Never Says "Play it again, Sam" in Casablanca

The most famous line in Casablanca is one that was never said. Despite being quoted for decades, the iconic “Play it again, Sam” was never uttered by Humphry Bogart — or anyone. The actual line doesn’t even come close to the misquote.

What Bogart really says in the film was a variation of the same idea, but nowhere near the wording that people think. What he said was, “Play it once, Sam. For old times' sake…Play it, Sam”. For such a legendary film, this is one surprising misquote from the film buffs who love it.

14 Darth Vader Doesn't Say "Luke, I am your father" in The Empire Strikes Back

Everyone misquotes Star Wars. Ask anyone, and they will say that the twist reveal in The Empire Strikes Back is easy to remember. It was “Luke, I am your father.”

Except that it’s not “Luke, I am your father.” The line is actually, “No, I am your father.” While most will assume that the original quote is too vague to be used in day to day movie-quoting — thus it was changed by many to name “Luke” — there’s one small problem: even James Earl Jones, the voice behind the famous line, remembers it the wrong way.

13 In Jaws, It Isn't "We're gonna need a bigger boat."

Another iconic film line. Another misquote that was never said. Apologies to children of the 80s who have quoted this Jaws line while entering a dock with friends, but no one says, “We’re going to need a bigger boat” in the film.

Seriously? Yes, seriously. The actual line uttered by Roy Schnieder was “You’re gonna need a bigger boat.” While close in wording, it makes a big difference. For some, it’s a simple error. For others, it’s a major issue as they swear the original line was “we’re” and not “you’re.”

12 "Magic Mirror on the wall," Not "Mirror, Mirror" in Snow White

You’d be hard-pressed to find many people who don’t think that the evil witch in Snow White and the Seven Dwarfs called her mirror “Mirror, Mirror.” The historic quote is actually “Magic Mirror on the wall.” How about them apples?

It sounds strange to say, and the countless misquotes through pop culture make it feel like a group error. From parodies to book titles, the stream of “residue” from “Mirror, Mirror” remains. While it might sound right to most people, those doing research and creating new pieces of art would most likely verify the wording. It’s a bizarre, and easily correctable, error that so many people seem to make.

11 Golden C3PO Has One Silver Leg

Quick, what color is C3PO? Gold? Cool. What color is his leg? Nope. Silver. If that one doesn't knock you for a bit of a loop, you might be an android.

This strange discovery has sent fanboys and fangirls into a tizzy, unearthing action figures from years gone by. See for yourself. Apparently C3PO, the beloved Star Wars robot has always had one silver leg. Even the most die-hard of fans have been scratching their head over this reveal.

10 Sinbad Never Made a Movie Called Shazaam

College Humor

In the mid-90s, Sinbad released a film called Shazaam. This movie about a genie, discovered by children in their attic, had some memorable moments. In the trailer, as the kids unearth the comic from his magic lamp, he appears in a puff of smoke. As he announces that he is the genie of the lamp, the children scurry, with one of them screaming, “It’s a kidnapper!”

Ah. Good times. One small detail, though: none of that happened. Shazaam, the film project, never happened. Your memories of it are based in fiction. This is one of the biggest Mandela Effects regarding an unmade movie as so many people share the same memories of it. You can hear quotes and descriptions of the VHS box. The unshakable feeling that this picture existed has even led to people accusing Sinbad and the studio of some sort of bizarre cover-up.

Sinbad has a sense of humor about the film. He has released parodies and YouTube videos portraying the genie that so many seem to remember. As he told IndieWire, “It came out of nowhere and nobody knows why.”

9 Big's Youthful Alternate Ending

A scene from Big
20th Century Fox

The ending to Big is a strange tale of tragedy and deceit for a boy who has to explain to the police, family, and friends where he has been. The final moments, showing a playful Josh Baskin walking into the distance, never address the horror that his mother had been through.

For many viewers, the movie had either an “alternate” ending or a post-credits scene that took things on a different turn. Many remember Elizabeth Perkins’ character making the wish to be “young” on that same Zoltar game. To those who remember things differently, the final moments of the movie see Perkins, as a ten-year-old girl, meeting Baskin at his classroom and walking off together.

That scene never happened. In fact, there has been a great deal of research to find any scene that is remotely similar. There’s simply no explanation for this misremembered moment and why, especially after you hear about, you can totally remember seeing it yourself.

Quick: what color are Mickey Mouse’s suspenders? White? Red with yellow dots? How about none? How about Mickey Mouse doesn’t wear suspenders?

You can find them on toys and third-party doodles, but look through your movie collection. The famous mouse wears high-waisted pants, but no suspenders. For any kid who has ever drawn Mickey during a particularly boring day in 5th-grade art class may beg to differ.

7 There is No “Hello, Clarice” in Silence of The Lambs

When you meet someone named “Clarice,” do you say “Hello, Clarice” in a scary voice? Does it remind you of Anthony Hopkins in Silence of the Lambs? It shouldn’t because he never says it. The famous line that so many recall Hopkins saying to Jodie Foster during their initial meeting was not “Hello, Clarice.” Rather, he simply said “Good morning.” That’s it. Nothing more, nothing less.

6 Risky Business Dance Scene Wardrobe Issues

Geffen Pictures

For decades, people have been dressing like Tom Cruise for Halloween. Emulating the Risky Business dancing scene, they would sing into a brush as they donned a white button-down shirt, dark sunglasses, and underwear. It was meant to match the movie exactly and, amazingly, only got one item right.

A glance at the film today reveals no white shirt or sunglasses. Rather, Cruise is wearing a pink button-down shirt with no eyewear on his face. Making things creepier? He doesn’t sing into a hairbrush either. In the film, he lip-syncs into a trophy.

5 Captain Kirk Never Says, "Beam me up, Scotty"

Nowhere in Star Trek does Captain Kirk say the exact phrase “Beam me up, Scotty.” It never happens. There have been cases of him saying “beam us up” or even “Scotty, beam me up,” but hardcore fans have been searching for the exact “Beam me up, Scotty” quote ever since this Mandela Effect was discovered. Like the Enterprise, searching for the mysteries of the universe, they have yet to find it.

4 “If you build it, he will come”, Not "They will come" in Field of Dreams

Gordon Company

Field of Dreams had a strong baseball-centric message. Plowing through his own cornfield because voices told him to, Kevin Costner is seen a kook within his farming town. Yet, he had to. Once he did, the town turned out. He knew they would. After all, the voice said that “if you build, they will come.”

The problem? The quote is “if you build it, he will come”. It referred to Terrence Mann, who was being summoned to the area by a greater universal power. Still, people misquote it and swear they are right to this day, decades since it first aired.

3 Spike or Stripe Gremlin?

Gremlins Remake Put on the Fast Track at Warner Bros.

Just as memorable as Gizmo, the main antagonist of Gremlins is a vile green monster named Spike. This fanged creature, created by feeding the furry little mogwai after midnight, was a huge toy from the 1980s. Everyone had a…Stripe doll?

That’s right. His name is Stripe, not Spike. Yet, for so many fans of the franchise, it has always been “Spike.” When this one was discovered a few years ago, it caused mass confusion and a spike…er, stripe in searches.

2 E.T....Home Phone?

Universal Pictures

Now, this is getting ridiculous. E.T.’s famous for a few things. His finger lights up, he likes Reeses, and he says “E.T. phone home.” Right?

Wrong. Even though you are picturing the exact scene in your head right now, it never happened. The Extra-Terrestrial never says “E.T. phone home”. Rather, he says that awkwardly worded “E.T. home phone.” Seem small? It would be, if this wasn’t the main line everyone remembers from the film.

1 Grease: "Systematic, Hydromatic, Ultramatic"

grease-lightning
Paramount Pictures

Go get your Grease DVD because this one is going to shock anyone who has ever sung along with the famous “Greased Lightning” song. Ask any musical fan of this production, and they will swear that the opening line is, “Guys, this car can be: ultramatic, systematic, hyyyydromatic. Why – it can be Greased Lightning!”

And yet, it isn’t. Rather, John Travolta sings, "Guys, this car can be: systematic, hydromatic, ultramatic. Why – it can be Greased Lightning!” What makes this one such a major issue is that it’s sung. So many people remember the sing-song way that the original misquote went. Yet, load up the film, see for yourself.
