Seo Moon Jo is a central character in the K-drama “Strangers from Hell” (also known as “Hell Is Other People”). Portrayed by Lee Dong Wook, Seo Moon Jo is a charismatic and seemingly kind dentist who runs a clinic near Eden Dormitory1. However, beneath his charming exterior lies a dark and sinister personality. Seo Moon Jo is revealed to be a psychopath and the leader of a group of cannibalistic killers residing in the goshiwon (a type of dormitory) where the protagonist, Yoon Jong-woo, moves in2. He takes pleasure in torturing his victims using dental tools, reflecting his profession2. His character is complex and chilling, making him one of the most memorable villains in recent K-drama history. Lee Dong Wook’s portrayal of Seo Moon Jo was intense and immersive, to the point where he had to remind himself that it was all just an act3. This role marked a significant departure from his previous characters and showcased his versatility as an actor.
