SLEEP: Official Trailer And Poster For Korean Horror Thriller From Magnet

SLEEP follows newlyweds Hyun-su (Lee Sun-kyun, PARASITE) and Soo-jin (Jung Yu-mi), whose domestic bliss is disrupted when Hyun-su begins speaking in his sleep, ominously stating, “Someone’s inside.”  From that night on, whenever he falls asleep, Hyun-su transforms into someone else, with no recollection of what happened the night before. Overwhelmed with anxiety that he may hurt himself or their young family, Soo-jin can barely sleep because of this irrational fear. Despite treatment, Hyun-su’s sleepwalking only intensifies, and Soo-jin begins to feel that her unborn child may be in danger. A new thriller from director Jason Yu, who worked with Korean legends Bong Joon-ho and Lee Chang-dong before making his debut film, SLEEP world-premiered in Cannes’ Critics’ Week. 

In his feature directorial debut, Jason Yu weaves a tale of increasing dread and the limits of unconditional spousal support, of how desperate a person can become when their loved ones are a danger to themselves and those around them, and how a forgotten slight can manifest as terror. Sleep has a healthy dose of humour, but it also earns its scares, both jump and slow-building.
