Shyamalan shared the news on Twitter:
It's taken 17 years but I can finally answer the #1 question I get, "Are you making a f#&@ing sequel to Unbreakable or what?"— M. Night Shyamalan (@MNightShyamalan) April 26, 2017
"Split" was a huge hit, earning more than $275 million worldwide on just a $9 million budget. And it followed on the heels of another hit, 2015's "The Visit." So, Shyamalan is on a hot streak.
So, how can "Glass" be a sequel to both movies? SPOILERS AHEAD!
In "Split," McAvoy played a kidnapper named Kevin Wendell Crumb with multiple personalities, including "The Beast," with superhuman strength. At the end of the movie, customers at a diner watch news coverage of the crimes and one remarked Kevin's similarity to another criminal who was confined to a wheelchair. Sitting next to that patron is David Dunn (Willis), who reminded her that his name was "Mr. Glass" (Jackson).
A few months ago, Shyamalan explained that he initially included Kevin in "Unbreakable" but had to cut him out. Now, he can bring together the three characters as he intended.
