Glass picks up right where Split left us. Bruce Willis’ David Dunn in pursuit of James McAvoy’s Kevin Wendall Crumb better known as The Horde. Soon events bring the two under the care of a Psychiatrist Dr. Ellie Staple (like at the center of comic books?…) played by Sarah Paulson. Kept under heavy guard as well as lock and key, Dr. Staple is convinced that they and many others suffer from a delusion that they are superheroes right out of a comic book. She is a specialist in such areas. We learn that she has been treating Samuel L. Jackson’s Elijah Price, the Title bearing Mr. Glass, sometime during his incarceration for his actions in Unbreakable. She is here to help! She seeks to cure them of this infirmary.
So this was before Split, now Split was Shyamalan’s comeback, this film has getting his foot back in the door, this was a low budget film done by Blumhouse and it did well enough they gave him the chance to do Split.
Outsider Casey (Taylor-Joy), attending a party none of her classmates want her at, is kidnapped along with Marcia (Sula) and Claire (Richardson) by an eerily calm and focused man who swiftly incapacitates Claire’s father, enters the car the girls are waiting in and knocks them all out before driving away.
