hyamalan expressed hope for a third installment following Split, saying, "I hope [a third Unbreakable film happens]. The answer is yes. I'm just such a wimp sometimes. I don't know what's going to happen when I go off in my room, a week after this film opens, to write the script. But I'm going to start writing. [I have] a really robust outline, which is pretty intricate. But now the standards for my outlines are higher. I need to know I've won already. I'm almost there but I'm not quite there."
