Glass is a 2019 American superhero psychological thriller film directed by M. Night Shyamalan. It serves as a sequel to Shyamalan's previous films Unbreakable (2000) and Split (2016), rounding out the "Eastrail 177 Trilogy". The film stars Bruce Willis as David Dunn, Samuel L. Jackson as Elijah Price/Mr. Glass, James McAvoy as Kevin Wendell Crumb/The Horde, and Sarah Paulson as Dr. Ellie Staple.
The movie picks up the story of Dunn and Crumb from Split, with Dunn now actively seeking out Crumb's many personalities, including the dangerous entity known as "The Beast". Their encounters lead to their being placed in a mental institution along with Elijah Price, also known as Mr. Glass, who is apparently comatose. There, they are placed under the care of psychiatrist Dr. Ellie Staple, who trains in treating those who believe they are superheroes.
As the three men are treated, it becomes clear that Dr. Staple believes all of them to be suffering from delusions of grandeur, and she works to convince them that their abilities are not real. However, Mr. Glass has a secret plan, and he slowly manipulates the others into working together to reveal their powers to the world.
The final act of the film sees the three characters engaging in a confrontation in a city skyscraper, culminating in a twist ending that winds up flipping the entire narrative on its head.
Overall, the film received mixed reviews, with some critics praising its ambition, while others criticized its pacing and heavy exposition. However, fans of Unbreakable and Split were generally pleased with the movie, which offered closure to their respective stories while also expanding on the larger universe of Shyamalan's interconnected films.
