Visible crew/equipment: When Michael Myers enters Harold's room at the institution and hands over the knife Harold says, "Michael Myers". If you look carefully on the wall on his right you can see shadows of camera equipment and wiring and also when he is walking past the window you can see a reflection of a camera.
Visible crew/equipment: When you see the two women at the mental institution, the camera angle is at their backs, the woman on the left is curious about Michael Myers. Before the other says that she decapitated a man, you see down the end of the hallway a man kneeling down, possibly a crew member. In the next shots of the hallway, he is gone.
