Jordan Peele's second film, Us, introduces viewers to the idea of an alternate universe, where our doppelgängers wreak havoc in the world below us. When the Wilson family go on holiday, their home is broken into by four strangers. The family soon discovers that the intruders look just like them, with evil motives to harm and terrorize them. The film features several different twists and turns, along with some shocking revelations that leave you completely stunned once it's over, much like the Inception ending. With standout performances from Lupita Nyong'o, Winston Duke, and Elisabeth Moss, you'll be thinking about Us long after you watch.
