Willis is returning to the role of security guard David Dunn, who is imbued with superpowers, while McAvoy is back as Kevin Wendell Crumb, a man with multiple personalities, including the creature known as The Beast.

Glass finds Dunn pursuing Crumb's superhuman figure of The Beast in a series of escalating encounters, while the shadowy presence of Elijah Price, aka Mr. Glass (Jackson), emerges as an orchestrator who holds secrets critical to both men.

Clark is back as Willis' son, while Woodard is returning to play Jackson's mother.

Anya Taylor-Joy, who starred in Split, is back as Casey Cooke, the only captive to survive an encounter with The Beast. Sarah Paulson is also on the call sheet in a new undisclosed role.

Shyamalan, who wrote the script and is directing Glass, is producing with Jason Blum. Ashwin Rajan and Marc Bienstock are also producing, while Steven Schneider will executive produce.

Clark, who was 13 when Unbreakable was released, was recently seen playing villain Werner von Strucker on ABC's Agents of SHIELD and had a run on TNT's Animal Kingdom. He is repped by Don Buchwald & Associates and Untitled Entertainment.

Woodard has appeared on recent episodes of The Leftovers, The Blacklist and People of Earth. She is repped by Shelter Entertainment and Bret Adams Agency.
