Continuity mistake: Right after the Rabbi is shot in the beginning of the movie by Dominic, we see the two prophets check to see what was taken from the office. We can plainly see the dead Rabbi take two deep breaths during this scene.
Continuity mistake: In the final scene, Dr. Lane enters Michael York's office, holding a gun to his head from ten feet. Then, we get a close-up of York talking. Back to a wider shot, Dr. Lane is now holding the gun two inches from York's head.
