Continuity mistake: Red is barefoot for a long period in the movie, but when they run to the boat she's wearing barely-visible slippers, presumably to protect her feet while running outside.
Adelaide Wilson: They look exactly like us. They think like us. They know where we are. We need to move and keep moving. They won't stop until they kill us... or we kill them.
Trivia: The voice of the Fun House Narrator is that of the film's director, Jordan Peele.
Question: This may seem simplistic, but what happened to the police who were meant to arrive in 14 minutes?
Answer: If the police arrive in 14 minutes, they would be dead and killed by their doppelgängers - Red, Abraham, ombre, and Pluto.
