This idea was scrapped when the plot got too complicated with the inclusion of Samuel L. Jackson's Elijah Price (Mr. Glass), and Kevin was shelved for 2016's Split, which re-opened the possibility for Dunn to fight the most powerful member of The Horde.
In a new clip from Glass, the long-gestating battle finally comes to fruition as Dunn's Overseer rescues a group of cheerleaders from a crazed, table-throwing James McAvoy. Blessed with super strength and the ability to sense the misdeeds of others, David is a formidable match for The Beast, but their fates are made unclear as the scene ends.
Check out the clip (from Entertainment Weekly) below:
The scene with the cheerleaders is from the trailers, making us suspect that this clip comes from the start of the sequel. It would be a great way to set the stage before Dunn and Crumb are carted off to the same mental institution as Price, who will later forge a partnership with The Beast.
In the same interview where he revealed that Crumb was meant to make his debut 19 years ago, Shyamalan mentioned that the film's first 20 minutes would focus on Dunn working as a crime fighter, comparing it to the prologue of a James Bond offering. The epic fight scene and eventual moment of Overseer and Beast falling out of a window into a bank of fog is a great (excuse us) jumping off point for the story.
