Continuity mistake: When they're in the shack, and the raptors are making the walls shake, the lights wire guard falls off the wall and lands in front of the door. We then see a closeup of the raptors starting to dig under the door, there's no sign of the light guard. We then cut back to a wider shot of the door, and the light wire guard falls off again. Eventually it shows a closeup of the light wire guard AGAIN falling off. (01:30:10)
