Squid Game season 2 behind the scenes facts opens with Netflix confirmed ensemble — Lee Jung-jae, Lee Byung-hun, Yim Si-wan, Kang Ha-neul, Wi Ha-joon, and a dozen new regulars per official billing.

Lee returns as Player 456 on a mission to destroy the game. TheWrap quoted him calling the year physically and mentally draining — the cast anchor of this behind-the-scenes guide.

Yim Si-wan, Kang Ha-neul, Wi Ha-joon, Park Gyu-young, Choi Seung-hyun, and Jo Yu-ri join as series regulars. Daejeon rehearsals required hundreds of matching tracksuits daily.

Lee Byung-hun deepens the Front Man role across seven episodes Hwang personally directed. Netflix billing lists him alongside Gi-hun as the season's dual spine.

Finale shootout stunt coordinators Park Young-sick and Chung Seong-ho ran seven days of training before seven to 10 shoot days on the six-month staircase build.
