When Squid Game premiered on Netflix in 2021, it transformed from a long-shelved script into a massive cultural phenomenon. Behind the candy-colored sets and high-stakes tension lies an intense production history driven by practical effects, meticulous set design, and breakout performances. Understanding how the first season came together reveals why it resonated so deeply with global audiences.
The production relied heavily on physical sets rather than computer-generated imagery. Director Hwang Dong-hyuk spent over a decade pitching the concept before production began near Daejeon, South Korea. By building massive practical environments—including the giant dormitory and the labyrinthine staircases—the cast experienced authentic spatial dread while filming.
The Real Craft Behind the Iconic Sets
Production designer Chae Kyoung-sun approached the visual language through the lens of childhood nostalgia warped by adult despair. Instead of relying on green screens, the crew constructed full-scale playgrounds and alleys.
- The Dormitory: Designed to mimic an Amazon warehouse, the bunk beds stacked high against the walls served a dual purpose. As player numbers dwindled, the art department removed beds to reveal hidden clues painted on the walls detailing upcoming games.
- The Pastel Staircases: Inspired by M.C. Escher's lithograph Relativity and Ricardo Bofill's architecture in Spain, these gravity-defying stairwells disoriented both the characters and viewers.
- The Giant Doll: The animatronic figure used in the opening game was borrowed from a horse-carriage museum in South Korea and returned after production wrapped.
Cast Dynamics and Breakthrough Performances
The series launched several actors into international stardom while giving veterans a gritty platform to showcase emotional range. Lee Jung-jae portrayed Seong Gi-hun with a disarming blend of desperation and warmth, while Park Hae-seo brought cold pragmatism to Cho Sang-woo.

For HoYeon Jung, who played Kang Sae-byeok, the series marked her professional acting debut. Drawing on her experience working abroad as a model, she channeled feelings of isolation into her character's guarded demeanor.
Wardrobe and Practical Challenges
The visual contrast between the green tracksuits and the pink guard jumpsuits became instantly iconic, but filming in them created unexpected hurdles.
- Dust and Allergies: The green athletic uniforms were fabricated from material similar to vintage gym wear. With hundreds of extras on set, the friction generated heavy dust particles that triggered allergies and respiratory irritation among the cast.
- Guard Uniform Evolution: The pink jumpsuits and fencing-style masks were originally intended to resemble Boy Scout uniforms. Producers abandoned that idea because those outfits outlined the actors' builds too clearly, opting instead for anonymous silhouettes inspired by ant colonies.
Common Misconceptions About Filming
Audiences often assume high-budget streaming series rely entirely on digital trickery. However, many of the most intense moments on screen involved hands-on physical execution.
During the tug-of-war sequence, actors didn't pull against a rival team. A heavy-duty mechanical puller was attached to the rope off-camera, forcing the cast to exert genuine physical strain against a machine. Similarly, the glass-stepping-stone sequence used real tempered glass panels raised a safe distance above the floor, though actors still reported genuine vertigo and fear.
Frequently Asked Questions
Was the phone number on the invitation card real?
Yes. The production team printed an active phone number on the business cards handed out in the early episodes. This caused real-world complications for an individual whose personal phone number matched the digits on screen, prompting Netflix to edit out certain sequences.
Did the actors actually eat the Dalgona candy during filming?
While the actors carved the shapes under strict time limits, special props teams prepared multiple iterations of the honeycomb candy. Some variations broke easily for close-up shots, while others were formulated to withstand actor handling.
Why did the guards wear different shapes on their masks?
The symbols established a strict caste system. Circles designated workers at the bottom rung, triangles represented armed soldiers, and squares denoted managers who oversaw operations.
How long did it take to write the first season?
Director Hwang Dong-hyuk wrote the initial feature-length screenplay in 2008. It took nearly twelve years before streaming platforms recognized its potential and greenlit the expansion into a multi-episode series.
