Visible crew/equipment: After Billy has grabbed Gizmo from the laboratory he walks into the men's room. When the voice says "I hope you washed your hands", you can see the camera man moving reflected on the wall.

Factual error: When the Security Guard in the pump room gets bitten on the nose, he starts shooting with his revolver (a SIX shooter). Count the bangs. He manages to fire SEVEN times.
