The Celebrity Traitors was filmed in the spring of 2025, starting on April 22 and continuing through May. The filming location was Ardross Castle in the Scottish Highlands, north of Inverness, Scotland. The production consisted of 9 episodes, and filming was kept highly secretive, with contestants confined to separate lodgings without access to phones or internet when not at the castle. The series premiered on BBC One on October 8, 2025, and was presented by Claudia Winkleman. Celebrity contestants played on behalf of charities, and the show's filming was described as a "military operation" due to its tight security and secrecy.
