It’s the story of Jaws, released in 1976. But it’s also the story of Beowulf, the Anglo-Saxon epic poem published some time between the eighth and 11th centuries.

And it’s more familiar than that: It’s The Thing, it’s Jurassic Park, it’s Godzilla, it’s The Blob—all films with real tangible monsters. If you recast the monsters in human form, it’s also every James Bond film, every episode of MI5, House, or CSI. You can see the same shape in The Exorcist, The Shining, Fatal Attraction, Scream, Psycho, and Saw. The monster may change from a literal one in Nightmare on Elm Street to a corporation in Erin Brockovich, but the underlying architecture—in which a foe is vanquished and order restored to a community—stays the same. The monster can be fire in The Towering Inferno, an upturned boat in The Poseidon Adventure, or a boy’s mother in Ordinary People. Though superficially dissimilar, the skeletons of each are identical.
