I honestly can't understand why this movie didn't get just as much recognition as The Exorcist (X1). It wasn't as graphic or controversial as X1 so perhaps that's why it didn't get the notoriety? The thing is, The Changeling is every bit as good. It's got a fantastic cast, with our old friend George C. Scott, and even the venerable Melvin Douglas. So the acting solid and matched by a great character driven plot with solid dialog. The over arcing premises of the plot is clever, and it was the first of it's kind at that time. The story was brilliantly plotted, tho a bit poorly paced. And while there are a few questions sort of just left to interpretation, the plot is strongly devoid of holes.
