In an era when Marvel is showing everyone how blockbuster franchises are done, it's easy to forget that M. Night Shyamalan built a superhero universe out of nothing.

The twist-loving filmmaker's upcoming Glass is due for a major San Diego Comic Con presentation in Hall H — the big room — on July 20. To give fans a taste of what to expect, Shyamalan released the first poster for the Jan. 18, 2019 release on Friday.

It speaks volumes.

But if you need your #GlassMovie fix before July 20th, here’s the world premiere of our teaser poster. pic.twitter.com/HsMa0bzR7N — M. Night Shyamalan (@MNightShyamalan) June 29, 2018

First, some explanation for those who may not be caught up: On the left and right sides of that image, respectively, we see Samuel L. Jackson's Elijah Price and Bruce Willis's David Dunn, the two stars of Shyamalan's 2000 release, Unbreakable. Then, in the center, we have James McAvoy's Kevin Wendell Crumb, the main character in Shyamalan's 2016 film, Split.

Without getting into heavy spoiler territory — both movies are good, and worth seeing if you've never caught them before — Unbreakable is meant to be an IRL superhero origin story and, by the time credits roll on Split, it's clear that the movie exists within the same universe.

This poster for Glass is noteworthy because it ropes all three of these characters together in a way that clearly defines each one's visual motif. Glass is meant to complete the trilogy that started with Unbreakable.

The poster reveal was met with enthusiasm all across the internet. Even though Unbreakable is almost 20 years old — and wasn't ever visibly built as the first movie in a series — and Shyamalan's been out of the spotlight since Split's release, there's still a lot of love for this unexpected superhero series.

I’m so excited to tell you that @GlassMovie will be at #ComicCon. I will be in Hall H on July 20th with the cast! You can expect a surprise as well… — M. Night Shyamalan (@MNightShyamalan) June 29, 2018

How fucking radical is it that @MNightShyamalan had us watch a film trilogy when we had no idea until the very end of the second and into the third film.



And it all started with one of my favorite films of all time

I just learned Shyamalan is making “Glass”, a followup to Unbreakable (which is really good!) and Split–a follow up from two years ago I didn’t know existed.
