Split turned out to be a great hit, and for many, a perfect example of just how talented M. Night Shyamalan can be, despite his many previous box-office flops. The original film was about 3 hours long, which the director later had to cut down to 2. That meant that some of the subplots had to be cut, of course. Among them, there was a scene with a doctor who gave more information about the protagonist’s syndrome. This part, which ended up being completely cut out of the film, was played by Sterling K. Brown before he rose to fame for his performance in American Crime Story: All Against O. J. Simpson and People Like Us.
