An establishing shot shows the door to Dr. Gillespie's hospital office is about 6 feet from the corner of two perpendicular hallways with guidance lines painted on the floor, indicating they are primary corridors that typically extend the length or breadth of a building. However, when characters enter the office, they move in the direction of the corner (to the right) into rooms that would have to be in the same space as the perpendicular hallway -- a physical impossibility.
