Divisive writer/director M. Night Shyamalan hinted at it before, but now he's revealed the full career twist: He's making his first-ever sequel, and it's the successor of both this past January's Split and 2000's Unbreakable. Of his dozen films, the Sixth Sense follow-up is the fan favorite Shyamalan gets questioned about more than any other.

The sequel's called Glass, and it'll bring back Samuel L. Jackson as the titular supervillain and Bruce Willis as the superpowered David Dunn.

The 46-year-old Shyamalan gave all the details on Glass on Twitter. The full text:

"Okay. Here we go. Finished the new script. 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?' My new film is the sequel to Unbreakable AND Split. It was always my dream to have both films collide in this third film.

The iconic Bruce Willis returns as David Dunn. The incomparable Samuel L. Jackson will return as Elijah Price/Mr. Glass. The virtuoso James McAvoy returns as Kevin Wendell Crumb, Patricia, Dennis, Hedwig, Barry, Jade, Orwell, The Beast, Heinrich, Norma, Pol– and the prodigy, Anya Taylor-Joy will return as Casey Cooke. 

I’m reteaming with my partners Jason Blum and Universal Pictures for this crazy comic book thriller. And the film is called GLASS… Universal Pictures will release Glass on January 18, 2019 all over the world. How’s that for not keeping a secret!"

Back in February, he teased, "I have an 11 page outline for my next film in my bag. I can't tell you what it is, but If you've seen Split..." He also told Entertainment Weekly of conjuring a sequel in Split's wake, "I don’t know what’s going to happen when I go off in my room, a week after this film opens, to write the script. But I’m going to start writing."

Split made $275 million and became Shyamalan's third-highest-grossing film in the U.S. The studio, Blumhouse, started with Paranormal Activity and has recently given us Get Out, the Purge moviesandM. Night's The Visit. His back-to-back horror successes in the last two years ended a long streak of critical dragging for products like After Earth and The Last Airbender.
