Squid Game: The Challenge was filmed at Wharf Studios in London. The production used a total of six interconnected sound stages to create a “completely immersive world” for gamers.
The only time the show was filmed elsewhere was during the Red Light, Green Light game. Cardington Studios in Bedford, Europe’s largest indoor space, was used to film Red Light, Green Light. The facility, which is over 100,000 square feet, was originally utilized to produce airships and zeppelins in the 1920s and 1930s.
A significant amount of effort was put into having the competition look exactly like it did in the drama series, including objects that were CGI’d into the original drama. For example, the piggy bank that the participants see fill up with money every time a contestant is eliminated was designed exclusively for Squid Game: The Challenge.
