Like Unbreakable, Split was met with positive reception, so shortly after its release, Shyamalan announced he’d be making Glass next.
The hype surrounding Glass only grew over the next two years (give or take), especially after the first trailer dropped last summer.
For nearly two decades Unbreakable was a standalone feature in M. Night Shyamalan’s filmography, but the filmmaker finally revisited that world with Split, which, in typical Shaymalan twist fashion, had Bruce Willis’ David Dunn appear at the end.
