M. Night Shyamalan’s worlds are colliding. In the new trailer for Glass, the hero of Unbreakable and the supervillain of Split violently cross paths in a cinematic battle almost 20 years in the making.

In the 2000 film Unbreakable, a security guard named David Dunn (Bruce Willis) is the lone survivor of a major transit accident, with nary a scratch on him. In consulting with an enigmatic and disabled comic book collector, Elijah Price — who eventually adopts the name “Mr. Glass” — David Dunn learns to wield his abilities whilst uncovering a massive conspiracy right in front of him.

In 2017’s Split, a lonely teenager named Casey Cooke (Anya-Taylor Joy) is kidnapped by a mentally ill criminal, Kevin, whose dissociative identity disorder hides a powerful, inhuman monster he calls “the Beast.” Along with his other personalities that give him either useful or useless skills (in one of them, he’s a pretty neat fashion designer), Kevin roams freely, with a hysterical media calling him “The Horde.”

The newest TV spot, released on Wednesday, is chock full of action and new scenes that the last two trailers didn’t show. And while Shyamalan’s cerebral superhero story isn’t based on any pre-existing property, there is still plenty to speculate about based on the trailer’s visuals and audio clues.

Here are five things to expect as revealed in the Glass TV spot.

5. “And yet, we exist.”

Are there more powered people besides David Dunn and the Horde? Samuel L. Jackson’s “Mr. Glass” talks like Professor X on behalf of mutantkind to Sarah Paulson’s psychiatrist, Dr. Ellie Staple, who inadvertently becomes a leading researcher in the emergence of superhumans.

Someone's mad.

4. “I need your abilities to get us out of here.”

No surprise, the villain of Unbreakable teams up with the villain of Split in an unholy alliance that does not bode well for the rest of us.

3. The Return of Joseph Dunn

In one of the most surprising returns to screen, actor Spencer Treat Clark reprises his role after 18 years as David’s son Joseph from Unbreakable. He can be seen in the trailer standing alongside Joy’s Casey, who returns from last year’s Split as the lone survivor of Kevin’s kidnapping.

2. Trauma Stays With You

In one of the most obvious references pointing out how Shyamalan’s superhero universe homaging classic comic books, Casey picks up a comic (specifically made for the movie, so don’t bother with any Easter eggs) that triggers her memory and fear of Kevin/the Beast from Split.

This looks bad.

1. “This won’t be like a comic book.”

And speaking of comic books, Glass is perhaps the most “comic book” movie of the entire trilogy as the trailers tease at the rawest action yet The first film, which was released in 2000 at the early dawn of the superhero boom, was celebrated for its aggressively cerebral take on the genre, which at the time was only familiar to audiences and wasn’t the singular driving force of pop culture like it is today.

So it stands to reason that Shyamalan, who tried his own hand at blockbuster epic studio filmmaking with 2010’s The Last Airbender (and completely bungled it), will try to stand apart from Marvel and DC with Glass. Maybe it’ll end without a clear winner (peep that shot of David and Kevin jumping out of a building together) and without a post-credits scene.

Glass will be released in theaters on January 18, 2019.
