10 Best "Everything You Know Is A Lie" Moments In Horror Movies

There isn't a movie-goer among us who doesn't love a mind-melting, Earth-shattering revelation that completely changes everything.

While many movies struggle to pull it off, either by not playing fair with the audience or simply getting too silly for their own good, these 10 films all thankfully knew a show-stopping, jaw-dropping reveal when they saw it.

Thinking the story will go one way and then having that expectation aggressively upended can be tremendously entertaining and satisfying in the right hands, and that's perhaps uniquely true in the horror genre.

Horror is arguably a genre more defined by tropes than any other, so it's always great to see smart filmmakers subvert the expected and deliver genuinely shocking twists which cause the audience to reconsider the "truth" of everything they've seen.

These 10 horror movies all framed the narrative and the protagonist's experience one way, only to pull the rug out and reveal that everything they knew was a falsehood.

When done right, it only supplements and enhances an intriguing story, and in the case of horror, proves that the genre has so much more to offer than gore and jump scares...

For almost the entirety of Friday the 13th's runtime, the film's ill-fated teenage camp counselors believe that they're being picked off by a back-from-the-dead Jason Voorhees, who drowned at Camp Crystal Lake as a child decades prior.

We as audience members similarly believe this, but at the very end of the movie protagonist Alice (Adrienne King) learns that Jason is indeed still dead, and the person carrying out the killings has been his psychotic, vengeful mother Pamela (Betsy Palmer).

Pamela reveals that Jason drowned because the camp counselors were having sex rather than looking after him, and then drops any attempt to conceal the fact that she's the murderer.

It's a genuinely shocking moment for both Alice and viewers, that what was laid out as an incredibly straight-forward slasher film had a nasty little sting in its tail, of a mother driven to murderous madness by her rage-fuelled grief.

Starting with the second film, though, the series indeed deferred to the more expected mode of Jason indeed returning from the grave and slaughtering nubile youngsters en masse.
