“Aren’t I much better looking in person?” Well Go USA has debuted the final official US trailer for the sci-fi thriller titled Paradise Lost, yet another new film coming out this same year directed by prolific Korean genre filmmaker Yeon Sang-ho (of Colony, Train to Busan, Jung-E, Hellbound, Revelations, The Ugly). And yet another new film about creating lost children with AI! Paradise Lost first premiered at the 2026 Toronto Film Festival to mixed reviews – some positive, some negative. A psychological thriller unfolds when a young boy, presumed dead in a school camping bus disappearance around 9 years ago, miraculously returns alive to his grieving mother, Ryu So-young. But she has already started using AR glasses to recreate her son Sun-Woo to cope with his loss. “This shatters So-young’s world once more — the real son is a cold stranger; the virtual son needs her more than ever.” Paradise Lost stars Kim Hyun-joo & Bae Hyeon-seong as mother & son. An intriguing, unsettling premise that looks like it gets even more twisted and peculiar as it plays out once this older Sun-Woo returns. What is he up to with his mom? And where was he anyway? Any guesses?
Here’s the final official trailer (+ poster) for Yeon Sang-ho’s movie Paradise Lost, direct from YouTube:

A bus carrying a group of children to camp vanishes. Only a few bodies are recovered before the case is cold-sealed. Among the grieving, So-young finds solace in reconnecting with her lost son, Sun-woo, with AR glasses.

But this shatters So-young’s world once more — the real son is a cold stranger; the virtual son needs her more than ever. At crossroads of loving guilt & manic salvation, she faces a devastating choice.
