Actor Michael Sheen joins the cast of the second season of The Celebrity Traitors, expressing concerns that his profession may make him a target for suspicion.

Actor Michael Sheen is among the 21 celebrities competing in the second season of the BBC reality series The Celebrity Traitors. Hosted by Claudia Winkleman, the program features contestants living in a Scottish castle while competing to identify "traitors" among them to win up to £100,000 for charity. The new season is scheduled to premiere on October 1 on BBC One and BBC iPlayer.

Actor's Perspective on the Game

Michael Sheen, known for his roles in Frost/Nixon and Good Omens, stated that he believes his background as an actor is a disadvantage in the game. He noted that other contestants may be inherently suspicious of him because they assume he is "pretending for a living." Sheen clarified that he views acting as a process of believing in the truth of a situation, rather than consciously deceiving others, and expressed uncertainty about how his public persona will influence his gameplay.

Show Format and Success

The Celebrity Traitors tasks contestants with banishing traitors to secure a prize fund for their chosen charities. The show’s first series, which aired last year, saw comedian Alan Carr win as a traitor. The debut season achieved significant viewership, with the finale reaching a peak of 15.4 million viewers and the series averaging 14.9 million, making it the largest television audience of 2025.
