Interestingly, Lee Jung-jae, who portrayed Seong Gi-hun in Squid Game, worked as a fashion model before debuting as an actor in 1993 with the TV drama Dinosaur Teacher. He also appeared in series like Feelings and Sandglass early on in his career, but his breakthrough role came in 1998 when he played U-in in the award-winning film An Affair, one of the highest-grossing Korean movies that year. Since then, Lee has starred in many other iconic Korean films, like Il Mare and The Housemaid (which got an American remake starring Keanu Reeves and Sandra Bullock called The Lake House), as well as Deliver Us from Evil and Svaha: The Sixth Finger.
