We don’t live in a world with the Men in Black memory wiping machine, but we collectively experience a similar kind of memory loss as a society through what is known as the Mandela Effect. It is named after Nelson Mandela, who many were convinced died in prison in the ’80s and not in December 2013, like he actually did.

The Mandela Effect is the phenomenon of many people misremembering something due to their confidence in their memories, often to the point that the misremembered factoid starts replacing the truth in collective memory. From fantasy movies that changed the genre forever, to horror movies that will always be classics, details in cinema have long been subjected to the Mandela Effect.

Some of the most iconic scenes are collectively misremembered by us as audiences, but the element of movies most commonly affected by the Mandela Effect is dialogue. The pure genius of some movie quotes, like Jaws‘ “You’re gonna need a bigger boat”, is often undercut due to people regularly misquoting them, saying “We’re gonna need a bigger boat“, for instance.

“Toto, I Don’t Think We’re In Kansas Anymore.” (“The Wizard of Oz”)

1939 was one of the best years in movie history, and of all the films released that year, Wizard of Oz undoubtedly had the biggest cultural impact. Through references, remakes, reimaginations, spinoffs, live performances and soundtrack covers, this film will perhaps always live on in public memory. Once you hear Judy Garland sing Over the Rainbow, you don’t forget it.

So, it’s no surprise that the Mandela Effect has affected such a widely popular film. One of the most quoted lines in the film comes when Dorothy realizes she has been magically transported to Oz. While many claim she says “Toto, I don’t think we’re in Kansas anymore“, she actually says “Toto, I’ve a feeling we’re not in Kansas anymore.”

“Run, You Fools!” (“The Lord of the Rings: The Fellowship of the Ring”)

The reverence that the fanbase rightfully has for the three The Lord of the Rings movies that will make you love the fantasy genre makes The Mandela Effect rare for them, especially when you consider that there are over eleven hours’ worth of memorable cinema that have been watched and referenced by so many around the world over the years.

However, while many still correctly remember Gandalf telling the other Fellowship members, “Fly, you fools” before being dragged into the depths by the Balrog, he is commonly misremembered as having said “Run, you fools.” A good way to remember the original quote is to realize he basically told them to fly to Mordor, like they eventually do, but much later.

“Mrs. Robinson, Are You Trying To Seduce Me?” (“The Graduate”)

1967 was a very different time, and movies like 50 Shades of Grey would have sent audiences at the time into a frenzy, possibly even causing literal riots over the presentation of such explicitly erotic and provocative material. So, while it may feel tame by today’s standards, The Graduate challenged the extent to which Sєxuality could be explored in cinema.

The sH๏τ of Dustin Hoffman framed by Anne Bancroft’s leg is the most iconic moment in the history of erotic cinema. It is also when he says the most quoted line from the film, “Mrs. Robinson, you’re trying to seduce me. Aren’t you?”, which is robbed of its confidence when misquoted as “Mrs. Robinson, are you trying to seduce me?”

“What If I Told You Everything You Knew Was A Lie?” (“The Matrix”)

Fandom culture was permanently changed and may have been shaped into its current form by the Wachowskis’ The Matrix. From people cosplaying in the slick wardrobe to digging deeper into the philosophical conundrums in the film, it created a whole subculture unlike anything before. Its timing bolstered the discussion of existentialism and created an online fandom that continues to grow.

While the movie features many of the best movie quotes in sci-fi history, one of its most popular lines is quite literally a lie peddled by meme culture. Morpheus’ famous “What if I told you everything you knew was a lie?” line takes on a meta quality because it should be addressed to the people who believe Morpheus says it.

“Hello, Clarice.” (“The Silence of the Lambs”)

Sir Anthony Hopkins’ Hannibal Lecter is a movie character who helped reshape genre expectations by challenging the popular stereotypical representation of psychopaths on the screen. A calm and calculated cannibal known for measuring his words and speaking deliberately, he’s a truly horrifying presence, and some of his words continue to be referenced in pop culture today, both satirically and sincerely.

While his eloquence has given us some spine-chilling movie quotes like “I’m having a friend for dinner.”, a commonly referenced line from The Silence of the Lambs was never said by him. He greets Clarice twice by saying “Good morning.”, and “Good evening, Clarice.”, but thanks to Jim Carrey’s impression in The Cable Guy, many remember Hannibal saying “Hello, Clarice.”

“Mirror, Mirror On The Wall, Who’s The Fairest Of Them All?” (“Snow White and the Seven Dwarfs”)

Disney’s first-ever animated feature film remains iconic to this day. 1937’s Snow White and the Seven Dwarfs didn’t just introduce the world to the talented animators and storytellers at Walt Disney Studios, but also helped start the subgenre of Disney movies that is still going strong, aka the Disney Princess movie. As an adaptation, it’s more famous than its source.

The movie’s most iconic line, arguably the most famous Disney princess movie quote, is regularly misquoted. While the mistake is small, it’s disorienting to realize she says “Magic mirror on the wall, who is the fairest one of all?” instead of “Mirror, mirror on the wall, who’s the fairest of them all?”, which is how many of us remember it.

“Play it again, Sam.” (“Casablanca”)

The number of ways Casablanca has shaped cinema as we know it today is impossible to account for. While the other effects are more commonly seen in technical elements of movies, the film’s biggest cultural impact can be experienced through the regular references to Casablanca‘s best quotes in pop culture. The most famous line even became a Broadway show’s тιтle!

Ironically, no one ever says “Play it again, Sam.”, in Casablanca. There are some alternatives in the movie though, like “Play it once, Sam. For old time’s sake.”, or “You played it for her, you can play it for me. If she can stand it, I can. Play it!”, or even simply “Play it, Sam. Play ‘As Time Goes By'”.

“Do Ya Feel Lucky, Punk?” (“Dirty Harry”)

His most iconic movie scene will forever be the climax of The Good, The Bad, and the Ugly, which inspired AC/DC to base Shoot to Thrill on Clint Eastwood’s shootout. However, the most famous line in his repertoire is not even from a Western movie, even though he’ll always be inextricably linked to the genre due to his timeless contributions.

Eastwood, as Dirty Harry, says one of the coolest lines ever, but he doesn’t really say “Do ya feel lucky, punk?”. “You’ve got to ask yourself one question: ‘Do I feel lucky?’ Well, do ya punk?” is how the real line goes. It is perhaps an even cooler line, but more verbose, which might explain why the misquote is popular.

“Luke, I am Your Father.” (“The Empire Strikes Back”)

There are many movie trilogies whose best film is the second one, but none of them are as famous as the Star Wars original trilogy. The Empire Strikes Back expands the lore of the Jedi and the Force, introduces Yoda, features Han Solo’s cockiest line, portrays Vader’s Force choke in all its glory, and is a masterclass in sci-fi filmmaking.

This is perhaps the most disorienting example of the Mandela Effect, because many swear by the misquote, but Darth Vader, despite most of us thinking so, doesn’t say, “Luke, I am your father.” The original line is “No, I am your father.” While that doesn’t affect the emotional impact of the scene, the popularity of the wrong quote is interesting.
