The concept of Jordan Peele's new film Us is fairly creepy on its own: The film follows the Wilson family on vacation in Santa Cruz, where they encounter underground, murderous versions of themselves. The red jumpsuit-wearing "villains" are the Tethered, underground beings bound to walk (literally) in the shadows of their above-ground counterparts and speak in twisted, cracked voices and guttural grunts. For very understandable reasons, that really pisses them off. So the film continues, in true horror film fashion, as the Tethered work to violently remove their unknowing captors, who are just doing their best to fight for survival. Peele has explained that the film is an introspective metaphor for the battles we fight within ourselves, which lends a sinister intimacy to the horror flick. But the actors who play both the Wilsons and their uncanny Tethered counterparts took it upon themselves to add a few more doses of terror themselves.
