Blumhouse Productions, Jason Blum alongside Marc Bienstock, Ashwin Rajan and Shyamalan are producing Glass.

In a recent interview, Jason Blum was asked if he had been made aware of Shyamalan’s plan to tie Unbreakable and Split together as a sequel in which he admitted he had no idea until the last minute.

“I did not know about it, I think Night has had this mapped out in his head for years. He would tease it out to me every now and again. He’s very private about that and kept it very much to himself. He had this thing all figured out, he’s a great strategic thinker that way and I really admire him for it”
