You might think you're ready for M. Night Shyamalan's Glass [1], but are you? Really? Because the first teaser for the third film in the series [2] — which includes 2000's Unbreakable and 2016's Split [3] — is only 15 seconds long, but it's more than enough to send a few chills down your spine.

The clip, though brief, features James McAvoy [4]'s Kevin Wendell Crumb casting an ominous glance at the camera through a pane of shattered glass, as his other personalities (Patricia, The Beast) flash in bursts around him. The film will follow Bruce Willis [5]'s David Dunn as he goes after Crumb, while also contending with Samuel L. Jackson [6]'s manipulative Elijah Price (code name: Glass).

There's no sign of Willis, Jackson, or costars Anya Taylor-Joy, Spencer Treat Clark, and Charlayne Woodard in the teaser, but we have a feeling the full trailer, which drops on Friday, will shade in more details about the explosive upcoming film.
