Joining from Split are James McAvoy, reprising his role as Kevin Wendell Crumb and the multiple identities who reside within, and Anya Taylor-Joy as Casey Cooke, the only captive to survive an encounter with The Beast. Following the conclusion of Split, Glass finds Dunn pursuing Crumb’s superhuman figure of The Beast in a series of escalating encounters, while the shadowy presence of Price emerges as an orchestrator who holds secrets critical to both men.
