James McAvoy's The Beast was first. Will Bruce Willis' David Dunn be next to get a "Glass" teaser, or will it be Samuel L. Jackson's Mr. Glass himself?

M. Night Shyamalan has waited 18 years for his sequel to "Unbreakable" to hit theaters. He had to wait at least 16 of those years for "Split" to arrive, pairing perfectly -- and surprisingly -- for a joint sequel. Fans didn't even know this was in the works until the end of "Split," but now they can't wait to see the result.

That sequel will share its first trailer this Friday, July 20 during San Diego Comic-Con.

To tease the upcoming trailer, Universal shared a brief video focused on one member of the superhero/villain trinity -- James McAvoy's The Beast (aka Kevin Wendell Crumb).

There's no new footage, it's basically a"Split" character profile to tide fans over as they wait for the trailer ... or the next character teaser, which could arrive on Wednesday.

Here's the first teaser:

The first photos were released last week, after the truly perfect first poster.

Here's the official "Glass" synopsis:

"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.

Joining the all-star cast are 'Unbreakable’s' Spencer Treat Clark and Charlayne Woodard, who reprise their roles as Dunn’s son and Price’s mother, as well as Golden Globe Award winner Sarah Paulson ('American Horror Story' series).

This riveting culmination of his worldwide blockbusters is produced by Shyamalan and Blumhouse Production’s Jason Blum, who also produced the writer/director’s previous two films for Universal. They produce again with Ashwin Rajan and Marc Bienstock, and Steven Schneider and Kevin Frakes, who executive produce. Gary Barber and Roger Birnbaum also serve as executive producers."

"Glass" will open in theaters January 18, 2019.
