Split: The Thriller That Was Secretly Something Else
★ Twist Score 8.5majorHorrorMysteryThriller
Split (2016, M. Night Shyamalan) spends most of its runtime as a grounded, claustrophobic thriller about dissociative identity disorder: Kevin Wendell Crumb’s twenty-three documented personalities, his therapist Dr. Fletcher’s careful management of them, and the three teenage girls he’s locked in an underground room beneath the Philadelphia Zoo. One alter in particular, “Patricia,” keeps warning the others that a twenty-fourth personality is coming – “The Beast” – and the film treats that warning with more dread than a psychological drama usually needs to. There are two reveals worth discussing here, stacked on top of each other: what the film decides to actually be about in its back half, and what it reveals about where it’s been standing the entire time.
Though Kevin has evidenced 23 personalities to his trusted psychiatrist, Dr. Fletcher, there remains one still submerged who is set to materialize and dominate all the others. Compelled to abduct three teenage girls led by the willful, observant Casey, Kevin reaches a war for survival among all of those contained within him – as well as everyone around him – as the walls between his compartments shatter.
The Twist
“The Beast” is not a delusion or a violent alter play-acting a legend – he is real. Once Kevin fully dissociates into the persona, his body develops genuine superhuman strength and resilience: he shrugs off shotgun blasts at close range and bends iron bars with his bare hands. The film commits to this fully rather than hedging it as a hallucination from Casey’s point of view, which pulls Split out of grounded psychological horror and into the same register as superpowered fiction. Then, in the film’s final scene, a diner patron tries to recall the nickname of a “wheelchair man” arrested fifteen years earlier for a string of disasters. David Dunn – present in the diner, having said nothing else in the entire film – supplies the answer without being asked: “Mr. Glass.” Split was a secret sequel to Unbreakable the whole time, set in the same universe where David’s own abilities are already a matter of record.
Why It Works
Shyamalan plants both halves of this fairly, even though the first reveal (The Beast’s powers are real) and the second (this is Unbreakable’s universe) land almost on top of each other. “Patricia” and “Hedwig” describe The Beast in escalating, specific physical terms long before he appears, so his strength isn’t dropped in without setup – it’s the payoff of a threat the other alters have been building the entire film. The David Dunn cameo is kept almost entirely wordless and unbilled in the credits, so nothing about the film’s marketing or opening scenes leans on the audience recognizing him; the reveal is earned through recognition, not foreshadowing you could point to on a first watch, which is a different but equally deliberate kind of restraint.
Shock Value
major rather than mind-bending because the two reveals pull in
different directions emotionally: The Beast’s powers escalate dread
you’ve already been primed for, while the David Dunn cameo is a jolt of
recognition that recontextualizes the preceding 100 minutes as belonging
to a different, larger story than the one you thought you were watching.
Critics covering the film’s festival premiere described it as one of the
most effective surprises in recent memory precisely because almost no
one going in expected a connection to a film sixteen years old.
Impact
Once the cameo lands, Split stops being a stand-alone thriller about one man’s condition and becomes the second chapter of a trilogy that began with Unbreakable and would conclude in Glass – Kevin’s arc was always going to collide with David’s. It also recasts the film’s treatment of The Beast: a story that read as (and was criticized for) sensationalizing a real psychiatric condition reveals itself, in hindsight, to be setting up a supervillain origin in a shared comic-book-inspired universe, which doesn’t resolve that criticism so much as explain the genre decisions that provoked it.
