A new synopsis for M. Night Shyamalan's Split follow-up Glass teases a confrontation between Bruce Willis' returning Unbreakable character Dunn and James McAvoy's inhuman The Beast. Split grossed $276 million worldwide at the box office against a budget of only $9 million, making it one of the most wildly successful horror movies of recent years.

With Split, M. Night Shyamalan returned to the top of the horror movie heap after a long absence during which he was reduced to crafting sub-par vehicles for Will Smith and his son, Jaden. Split starred James McAvoy as Crumb, a man with multiple personalities kidnapping a trio of young women and keeping them captive, but as the story unfolded McAvoy's true nature was revealed to be much more terrifying than it first seemed.

Glass will be the follow-up to Split, with McAvoy returning alongside Bruce Willis who is back in the Shyamalan universe playing his character Dunn from the movie Unbreakable. A new synopsis for Glass teases that Willis and McAvoy will become adversaries:

Following the conclusion of Split, Glass finds Dunn pursuing Crumb’s superhuman figure of The Beast in a series of escalating encounters, while the shadowy presence of Price emerges as an orchestrator who holds secrets critical to both men.

Unbreakable Shyamalan Bruce Willis

Samuel L. Jackson is also returning to play the character of Elijah Pryce, whom he originated in Unbreakable alongside Willis. Anya Taylor-Joy, who played one of the captive females in Split, is also returning for the sequel. Ryan Murphy favorite Sarah Paulson has also reportedly been added to the cast. Jason Blum of Blumhouse Productions is producing for Universal.

Shymalan cleverly built anticipation for Glass by culminating Split with a surprise appearance by Bruce Willis as Dunn, then quickly moved to capitalize on the film's success by speeding ahead with the writing process. For Shymalan, Glass represents a chance to revisit the world he created in Unbreakable, his 2000 smash hit starring Bruce Willis as a man who discovers he can't be hurt pitted against Samuel L. Jackson as Elijah Pryce, a man so fragile he's known as "Mr. Glass.

Blumhouse is on quite a run with their two huge hits Split and Get Out dropping in 2017. With Split and now Glass, M. Night Shyamalan is back close to where he was when he became the modern-day master of suspense/horror with his films The Sixth Sense, Unbreakable, Signs and The Village. If Glass works out as well as Split, what seemed like somewhat of a gimmick appearance by Willis will instead look like a stroke of genius.
