Sleep

Soo-jin, newly married and pregnant, notices her husband Hyun-su behaving strangely in his sleep. He gets up at night, scratches his face, eats the raw meat in the fridge, goes out onto the balcony. He remembers none of it. Doctors call it a sleep disorder; she starts to believe another explanation. The film is not interested in whether this is illness or possession. It is interested in the marriage: its motto hangs on the wall of the flat, that together they can solve any problem. Soo-jin sets out to apply that sentence literally, and that is where it turns horrific. The form is tight: a single apartment, a structure in three parts, and tension sustained even in daylight. The fear comes not from effects but from ordinary household objects. It is Jason Yu's first film. He worked on the set of Bong Joon-ho's Okja, and Bong was the first person to read the script; Bong called it the most unique horror and the smartest debut he had seen in ten years. The film screened in Critics' Week at Cannes in 2023. Jung Yu-mi and Lee Sun-kyun star. Who it is for: viewers who like single-location horror and endings left open. Who it is not for: anyone who wants a clear answer. The film keeps both explanations live to the last scene and leaves the verdict to the audience.
