Trivia: The "Prime Video" includes a goof/factual error stating: "At 18:26 when Ben looks in the refrigerator there is definitely light illuminating the interior despite there supposedly being no electricity in the house.

Stay hidden" and Ben later flicks off the light switch. The reported "factual error" is nonfactual. (00:04:35 - 00:12:07)
