Revealing mistake: In the next to last scene of this episode during the Sawtooth earthquake, while boulders are falling and trees are being uprooted, West, Gordon, and Faith are not struggling to keep their balance so as not to fall, they are just motionless standing - something that cannot happen with such a strong earthquake. The camera, which is shaking, attempts to make it look as if the three are shaking with the earthquake.11291929
Revealing mistake: In the opening earthquake scene right before the freeze frames appear, West and Gordon are in the bar. The glasses and pitcher on the bar by the bartender, the bottles of liquor behind the bartender, the bottle on top of the piano, and the ashtrays on two tables never move out of place, even though other tables have broken, chairs have toppled, the ceiling is destroyed, and the support beam falls. It is obvious the camera is doing the shaking, not the ground.
