A lot has changed for Seong Gi-hun in the three years since he won the Squid Game. He's a lot richer, of course, and more than just a tad traumatised. He's also reverted back to his natural hair colour, which is a win for everyone. But in the gap between seasons one and two, the show itself has evolved a great deal as well.

The finale climax also required a lot of time and effort. Building the set of various bright staircases “took roughly six months,” per The Wrap. The actual action required seven days of training from the stunt coordination team. And filming itself “took between seven and 10 days.”

During Gi-hun's rebellion against the organizers of the Squid Games, you can definitely see a camera guy in the background filming different angles. Check it out!

As millions of fans tuned into a brand new season of Squid Game, eagle-eyed viewers spotted an editing mistake during a pivotal moment in the finale. In the last episode of the season, Gi-hun ( Lee Jung-jae) and the remaining players stage an attack to put an end to the games once and for all.
