Production.
Shyamalan revealed that Kevin Crumb was going to be the secondary villain of Unbreakable but he felt it would make the movie too complicated. Since the movie was made by Universal instead of Touchstone Pictures, Shyamalan asked the Walt Disney Company to use David Dunn as a character and got to use him for free in exchange for a follow-up to both movies.
