The movie will include James McAvoy’s character The Horde from Split, as well as both Bruce Willis’ David Dunn and Samuel L. Jackson’s Mr. Glass from Unbreakable.
One of those questions has seemingly been answered, because it looks like Samuel L. Jackson will be involved in the sequel.
Samuel L. Jackson couldn’t say for sure if Split 2 is definitely going to get the go-ahead, but he seemed to think that the math checks out.
While speaking with Collider, Samuel L. Jackson explained how he learned about what Shyamalan had up his sleeve and talked about his potential involvement.
