Celebrity Traitors star James Acaster has compared being on the BBC show to living in Soviet-controlled East Germany during the Cold War, in an extraordinary interview that lifts the lid on the show's gruelling conditions.
The comedian has already complained to bosses about the punishing regime on the BBC One programme, which aired its fifth episode this week. Speaking to The Times, he was asked whether being on the pre-recorded show was like living in Communist-era Berlin.
"I think people who lived under the Stasi might have a thing or two to say about that comparison, but it is intense," Acaster replied. "People who watch the show always say, 'It's just a game.' That's good advice - not just to the players but to the production [staff]."
Acaster revealed that contestants are allowed just ten minutes on a producer's phone, with a chaperone present, to speak to their loved ones. The presence of a production team member means "you can't have an authentic conversation because you can't tell them anything that's happening."
He described one surreal exchange: "At one point my partner said, 'Have you caught the sun?' I was saying, 'Oh yeah, we were outside for one of the missions.' I was told I couldn't even tell her that."
His comments echoed those of another unnamed contestant who said earlier this week that the producers were like "human traffickers" for keeping participants confined in a hotel with very limited time to speak to their families.
Acaster's remarks come as the show dominates the national conversation. The second series launched to record audiences, with Richard E Grant's astonishing admission that he was a Traitor after just 30 minutes, and a racism row over the banishment of actress Myha'la, who agreed "unconscious racial and cultural bias" exists in the game - a claim insiders called "ridiculous."
On the show itself, Acaster is one of the Traitors alongside Maya Jama and mathematician Hannah Fry, and has been central to some of the series' most dramatic moments, including the "murder" of comedian Rob Beckett in a deadly game of hide-and-seek.
The revelations about filming conditions have sparked debate about how far reality television should go in the name of format integrity. Producers argue that strict isolation is essential to the social-deduction format - any leak could destroy weeks of filming - while critics say the psychological toll on contestants, who spend weeks cut off from normal life, deserves more scrutiny.
Acaster, known for his dry and often self-lacerating stand-up, appears to have approached the experience with characteristic irony. But his comparison to East Germany, however qualified, is the most striking public criticism yet from a contestant of a show that has otherwise been celebrated as a ratings triumph for the BBC.
