Trivia: The filmmakers wanted to honor the fact that the villains are animatronic robots and decided to use practical effects instead of CGI.

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. In addition, he sets his flashlight on the table so it can't be from that." To the contrary, there is no apparent power outage. Jack leaves Ben a note stating "Keep lights off. Stay hidden" and Ben later flicks off the light switch. The reported "factual error" is nonfactual. (00:04:35 - 00:12:07)
