'Glass' is a sequel to 2 movies, including a Disney movie from over 18 years ago — here's what to know before seeing it (2024)

The sequel picks up right where "Split" left off. While "Glass" will explain everything pretty neatly for you, you may still find yourself confused over a few things. If you don't have time to watch both before tuning in to "Glass," Insider rounded up what you need to know about Shyamalan's two previous films.

1. Bruce Willis' character, David Dunn, learns he has super strength after surviving a train crash

David is the sole survivor of a terrible train crash early in the movie. Not only does he survive the Eastrail 177 crash, but a doctor (played by "House of Card's" Michael Kelly) is astonished that he walked away without a scratch.

Throughout the movie, we learn that David has never really been sick or injured in his life and it leads to the discovery that he has super strength.The origin of his powers are never really explained, but we see him lift around 350 pounds. (A deleted scene from the film shows him lift around 500 pounds.)

David also receives premonitions or feelings about danger just by touching others.

2. David's weakness is water.

In "Unbreakable," it's revealed he nearly drowned in a school pool while young. As a result, he spent a week in a hospital with pneumonia. Again, it's never clarified how exactly water affects him, but it's referred to as his kryptonite and appears to weaken him.

3. Elijah Price/Mr. Glass is the exact opposite of David. He has very brittle bones, which easily break.

Elijah tells David he was born with type I osteogenesis imperfecta, a disease that makes his bones extremely fragile. In "Unbreakable," he says he has suffered over 50 breaks in his body. Regardless, Price is also a mastermind who is well-versed in comic-book lore.

We eventually learn he's responsible for the train crash and a number of other horrific accidents which have killed dozens. He set the accidents in motion, hoping to find someone who was his exact opposite.

4. Kevin Wendell Crumb is a man with dissociative identity disorder and exhibits 24 different personalities.

Introduced in "Split," Crumb (James McAvoy) takes on multiple personalities after his father mysteriously leaves his life. The other personalities become a coping method to protect him from verbal and physical abuse of his mother.

Collectively, the identities refer to themselves as The Horde. Kevin's 24th personality, the Beast, is revealed in "Split" and appears to have superhuman abilities. He climbs walls, becomes larger in size, and is able to bend bars.

We never see McAvoy perform as all 24 personalities, but we do get to see all two dozen names pop up on a computer screen in "Split."

The main identities include Dennis, a man with OCD; Miss Patricia, a controlling matriarch; and Hedwig, who identifies as a nine-year-old boy.

5. Kevin kidnaps and kills a few girls in "Split." The only one who escapes will appear in "Glass."

The main plot of "Split" revovles around Kevin's character capturing three teenagers and holding them hostage. Casey, a victim of sexual abuse at the hands of her uncle, winds up being the only survivor of Crumb's kidnapping when the Beast gleans they have more in commonby seeing scars all over her body.

6. If you say Kevin's full name three times, he'll revert to his normal self.

Kevin's therapist in "Split" made this discovery and we see it utilized effectively by Casey near the film's end.

7. If you haven't already guessed, trains are very important to the franchise.

At the end of "Unbreakable," David learns Elijah is responsible for the Eastrail 177 train crash, connecting the two. As a result, Elijah is sent to an institution for the criminally insane.

In 2017's "Split," we learn Kevin's father left on a train and never returned home. Late in the film, Kevin heads to a train terminal and leaves flowers on a platform before becoming the Beast. It's never made clear in "Unbreakable" or "Split" whether or not the two trains are connected, but fans have theorized they may, leading someto call the collection of three movies the Eastrail 177 trilogy.

8. "Glass" takes place ~19 years after "Unbreakable," but pretty soon after the end of "Split."

David Dunn tells a character in "Glass" he used to work as a security guard in a stadium 15 years ago. But later in the movie, Elijah makes it clear that the train accident David was in occurred 19 years ago.

"Glass" picks up not long after the end of "Split" where Crumb is on the run from authorities after Casey is found. At the very end of "Split," David Dunn is shown watching a news report about Crumb, who's being referred to as The Horde. He decides to take on his vigilante persona at the start of "Glass" to track him down. Early in "Glass," David's son says the incident at the Philadelphia Zoo in "Split" took place a few weeks ago.

9. Color is very important to the franchise.

If you didn't pick up on it from the "Glass" trailers, colors are used to dictate characters. In "Unbreakable," purple is representative of Elijah Price (Samuel L. Jackson) and his mother while David Dunn's (Bruce Willis) green security guard poncho becomes a significant color for him. In "Split," a bright yellow handkerchief denotes the color viewers identify with Kevin Wendell Crumb (James McAvoy).

All three colors are represented in one of the first images released for "Glass," seen above.

10. The boy who played David's son in "Unbreakable" reprises his role in "Glass."

If the man who plays David's son, Joseph, in "Glass" looks familiar from the trailers, it's because it's the very same actor who played young Joseph in 2000's "Unbreakable." Spencer Treat Clark told Da Man magazine the possibility of a sequel was something he had heard about for a long time.

"For almost two decades there has been chatter about a sequel to 'Unbreakable'but I never thought it would happen," said Clark. "'Split'caught me completely off guard. I had no idea there was a crossover with 'Unbreakable'until my phone started blowing up with messages from friends who saw it on opening night."

You may recognize Clark from roles on "Agents of S.H.I.E.L.D," "Animal Kingdom," and Netflix's "The Chilling Adventures of Sabrina" over the years.

He won't be the only other returning character from "Unbreakable." Charlayne Woodard will also reprise her role as Elijah's mother. A photo released for the film shows her character interacting with both Joseph and Casey.

11. McAvoy's character from "Split" was originally written for "Unbreakable."

You can appreciate the connection between the three movies when you know that Kevin Wendell Crumb was a character who appeared in the original script for "Unbreakable." M. Night Shyamalan told The Hollywood Reporter he removed Kevin from the film because it wasn't working and he had a big idea for the character.

"Kevin Wendell Crumb was a part of the original, original script for 'Unbreakable.' I pulled him out because it just wasn't balancing right," Shyamalan told THR's Aaron Couch. "But a bunch of the scenes that are in this movie, I wrote 15 years ago. They were as is. Patricia opening the door. Hedwig's first scene. Those were all written already."
