Never underestimate the mastermind.

Universal released a new trailer for "Glass," the follow-up to both 2000's "Unbreakable" and 2016's "Split." It lays out more of the M. Night Shyamalan's story, which centers on Elijah Price (Samuel L. Jackson) aka the villainous Mr. Glass.

Elijah is locked up in an asylum, seemingly sedated until the arrival of two new inmates. The first is nemesis David Dunn (Bruce Willis), who has superhuman strength. But more interesting is Kevin Wendell Crumb (James McAvoy), who exhibits multiple personalities. And Mr. Glass plans to use one of them, the fearsome Beast, to unleash his nefarious plans on the world.

Everyone was surprised when "Split" turned out to exist in the same universe as "Unbreakable," but it looks like "Glass" brings those two tonally different movies together in an entertaining and compelling way. And it'll certainly be a treat to see Mr. Glass and the Beast collaborating in their diabolical ways.

"Glass" opens in theaters January 18.
