10 More "Everything You Know Is A Lie" Moments In Movies

The Cabin in the Woods begins with a scene involving a few lab engineers discussing a mysterious operation in Stockholm before alluding to an employee betting pool.

And as this horrific comedy unfolds, it soon becomes clear that these lab coats were actually all in on what appeared to be a very peculiar experiment; one that involved the team unleashing various different monsters on a group of random teens during a weekend break.

It was only after the final two survivors, Dana and Marty, discovered said underground facility, and unleashed the many horrifying creatures within, though, that the truth behind this operation was revealed.

In a hilariously shocking final few minutes, the leader of this facility informs the pair that they were actually part of a sacred ritual that had been going on all over the world every year.

And with all the other rituals failing this time, if this particular bunch of slasher movie archetypes weren't killed, with the Whore dying first and Virgin falling last or surviving, the world would be reclaimed by the Ancient Ones below who once ruled the planet.

These two oblivious American students, along with the majority of the planet, had no clue they were only ever a few failed rituals away from extinction each and every year.

But not even the Director's late bombshell could keep Dana and Marty from deciding that the human race likely deserved this Ancient fate as they enjoyed one last joint in the moment's pre-giant hand arrival.
