Michael Sheen has been named in the season 2 cast of The Celebrity Traitors, the One and iPlayer series due to air later in 2026. The reveal puts another high-profile name into a format built around celebrity competition for charity, with Claudia Winkleman returning as host.
Romesh Ranganathan on the game
Romesh Ranganathan said, “Even as I begin to speak now I feel incredibly nervous because I can’t give anything away, but what I can say is, I thought that it was faker than it is.” He added, “What I mean is, I thought you rock up, just have a go, and then you go home.”
He also said, “You are in the game the whole time you’re in the game and that took me by surprise.” For a show that depends on secrecy, that kind of comment is useful because it tells viewers the format is not built around quick, isolated appearances; it keeps players inside the game loop for longer.
£100,000 for charity
The Celebrity Traitors will see celebrities battling to win a share of a £100,000 cash prize for their chosen charity. That gives the cast list a straightforward business-like hook: the entertainment value is tied to a charity pot, not just to who is on screen.
Romesh Ranganathan called the experience “it is so immersive” and said, “It becomes all-encompassing, it’s a pretty amazing experience.” That is the complication in the format. It sounds light on paper, but the game clearly asks for more than a few rehearsed TV appearances and a polite exit.
One and iPlayer
Claudia Winkleman will return as host when season 2 airs later in 2026 on One and iPlayer. Michael Sheen’s presence matters because the cast is being positioned as a larger ensemble rather than a single-name vehicle, which is the right way to build anticipation for a return series.
The cleanest read is that the reveal is doing its job: it adds one more recognizable figure, keeps the charity stakes front and centre, and leaves the format to do the selling when the season arrives later in 2026. The remaining cast roll-out is the main open point, and that is exactly where the show still has room to keep momentum alive.
