Part of what makes "The Circle" so interesting is that catfishing is not only accepted, but also encouraged. Because the contestants interact virtually, they can lie about their age, gender, occupation, and/or anything else they want to falsify to gain popularity. The series' production may be the ultimate catfish, though. As noted by Bustle, "The Circle" uses setting shots of Chicago to orient viewers to the show's location, but it's actually filmed elsewhere.

In fact, it's not only shot in a different city, but also in a different country. More specifically, "The Circle" is filmed in an apartment building in Salford, England — and, yes, all of the contestants actually live in the same building during filming (via Heart). What's even more fun is that the series films in the exact same building that the U.K.'s version of "The Circle" films in.

"The Circle" has filmed at least one season during the COVID-19 pandemic, but producers have taken the virus seriously. "We're creating a huge fortress, a sort of sealed environment where we'll be able to control who comes in," producer Stephen Lambert explained (via Bustle). "Obviously the subjects are already isolated, so it suits what's going on, but we'll have contestants tested beforehand and we're discussing having them quarantined after they arrive in England."

As for Salford's whereabouts — if you're unaware, the city is located in Greater Manchester in the northwest portion of England (via Get The Data).
