9. The Opening Shot Explains The Twist - Us
Jordan Peele's Us once again sees the filmmaker relishing toying with his audience, hiding literally dozens of Easter eggs and narrative clues throughout the film.
The best of all actually appears in the very first shot, though, when a commercial for Hands Across America is playing on a TV, and a VHS copy of the 1984 cult horror movie C.H.U.D. is visible on the left-hand side.
In the film, C.H.U.D. stands for "Cannibalistic Humanoid Underground Dwellers," and the plot revolves around New York City's homeless population living underground in the city's sewers, where they're turned into the titular monsters by radioactive toxic waste.
While on its own the C.H.U.D. VHS may not seem like an overt hint at the narrative of Peele's film, when you combine it with the ambiguous opening title text, it spells out the central plot pretty clearly:
"There are thousands of miles of tunnels beneath the United States. Abandoned subway systems, unused service routes, and deserted mine shafts. Many have no known purpose at all."
In the end, it turns out that the movie's terrifying, murderous doppelgangers - known as the Tethered - are actually government-created clones which have been abandoned to live, even dwell, underground since the government experiment failed.
The Tethered may not be cannibals, but their plan does involve replacing their above-ground originals, so it's not a million miles away either. Basically, it all comes back to C.H.UD.
