'Glass' Trailer: "People Are Going To Get Hurt" In M. Night Shyamalan's New Movie

Everyone's trapped under one roof in the latest Glass trailer. M. Night Shyamalan's sequel to both Unbreakable and Split brings characters from both of those films together, and sets them loose inside a mental hospital. This new trailer leans heavily on Samuel L. Jackson's ominous narration, as his character Elijah Price, AKA Mr. Glass, sets things in motion. "A lot of people are going to get hurt," he says at one point, and it's clear he's not very upset about that. Watch the new Glass trailer below.

While other trailers for M. Night Shyamalan's Glass haven't shied away from the mental hospital setting, they've also made sure to give us a glimpse of the outside world. This latest trailer is different, though. It's entirely self-contained within the hospital, making it look as if the film has only one specific setting. I'd personally be fine with that, but we all know M. Night has some tricks up his sleeve that he's not giving away just yet.

In Glass, Bruce Willis' David Dunn, who was revealed to be a real-life superhero in Unbreakable, finds himself locked up in an asylum alongside Elijah Price, AKA Mr. Glass, who fancies himself a super villain. And they're not alone. Kevin Wendell Crumb (James McAvoy), the man inflicted with split-personalities from Split, is in there too. From the looks of things, Mr. Glass plans to use Kevin – and his many personalities – for nefarious means, and only David can stop them. Unfortunately, their doctor, played by Sarah Paulson, wants to convince them all they're just crazy, and that they don't have super-abilities at all.

As a Shyamalan fan, it's great to see him back on top. There was a period where his career was in such shaky shape that trailers were afraid to show his name (his 2013 sci-fi film After Earth didn't advertise his involvement at all). Now, the filmmaker has redeemed himself, starting with the fun found footage thriller The Visit, and following it up with Split. Now, Glass takes him back to the world of one of his very best films – Unbreakable. I'm excited about all of this; my only complaint is that we have to wait until next month to see it.

Glass opens on January 18, 2019.

M. Night Shyamalan brings together the narratives of two of his standout originals—2000's Unbreakable, from Touchstone, and 2016's Split, from Universal—in one explosive, all-new comic-book thriller: Glass. From Unbreakable, Bruce Willis returns as David Dunn as does Samuel L. Jackson as Elijah Price, known also by his pseudonym Mr. Glass. Joining from Split are James McAvoy, reprising his role as Kevin Wendell Crumb and the multiple identities who reside within, and Anya Taylor-Joy as Casey Cooke, the only captive to survive an encounter with The Beast. 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.
