M. Night Shyamalan recently announced that “American Horror Story’s” Sarah Paulson has joined the cast of Glass, his Unbreakable sequel that will spin off from his surprise hit Split.

Unbreakable‘s antagonist Samuel L. Jackson returns as Elijah Price/Mr. Glass, while Bruce Willis reprises his role as the film’s hero, David Dunn.

Anya Taylor-Joy, who escaped Split, also stars with James McAvoy returning as Kevin Wendell Crumb, Patricia, Dennis, Hedwig, Barry, Jade, Orwell, The Beast, Heinrich, and Norma.

With Universal planning to release Glass in theaters on January 18, 2019, Jackson revealed to Collider that filming is set to begin next month: “We start rehearsal on [September] 18th and I start shooting on the 25th.”

In the 2000 Unbreakable, Willis’ character learns he’s a superhero with superhuman strength, while Jackson becomes his adversary, Mr. Glass. In Split, McAvoy’s multiple personalities include a monster, who is now on the loose in this newly invented Shyamalan universe. Glass will bring all of these characters together.
