Squid Game writer and director Hwang Dong-hyuk has revealed why main character Seong Gi-Hun made the drastic decision to dye his hair red. 

The show, which is set to become one of Netflix’s most popular series, concluded with Gi-Hun making a drastic appearance change using his winnings.

In an interview with Zapzee, the director added he was “thinking about how Gi Hun should change his hair in a hair salon. I imagined being him and thought to myself, ‘what is the colour that you would never choose to dye your hair?’”

“Then I came to the conclusion that Gi-Hun would never dye his hair red. It would be the craziest thing for him to do. So I chose the colour and I thought it really showed his inner anger.”

This quashes the popular rumour that the red hair dye symbolised Gi-Hun potentially becoming a guard in an unannounced season 2, in an attempt to break the system.

Squid Game has become a global phenomenon, with CEO Ted Sarandos stating that there’s “a very good chance it’s going to be our biggest show ever.”

He added, “Squid Game’ will definitely be our biggest non-English language show in the world”.

The dystopian show sees cashless members of society battle it out for a hefty ₩45.6 billion (or £28.2 million) through various children’s games. The catch, however, is that if you lose the game, then you are killed.

Audiences have already been asking for a second season, with the cliff-hanger ending showing an angry Gi-Hun walking away from his plane. Audiences have interpreted that the intense phone call with the Front Man and Gi-Hun’s decision to walk away from his family shows he is prepared to expose and end the games once and for all.

Discussing the potential for a second season, Hwang Dong-hyuk added: “I have some plans in my mind, but I should talk to Netflix about it first. I lost six teeth, and I got implants filming the first season, so I’m a little worried”.

“If I do get to do one — one would be the story of the Frontman [a former cop who now oversees the game]. I think the issue with police officers is not just an issue in Korea. I see it on the global news. Maybe in season two I can talk about this more.”

Squid Game is now streaming on Netflix.
