Richard E. Grant broke Celebrity Traitors UK's biggest secret within five minutes

Richard E. Grant looked like a dream pick for Celebrity Traitors UK. Then the Oscar-nominated actor did the exact opposite of what a hidden traitor is supposed to do and exposed himself almost as soon as the game began.

Grant arrived with the kind of screen history that made him seem built for this role. He is the first Oscar-nominated participant to appear on any version of the international Traitors franchise, and he is well known for villainous parts in films including Logan and Star Wars: The Rise of Skywalker. That made him an obvious choice when Claudia Winkleman and the production selected him as one of season two's traitors.

What happened next is what turned the opening episode into instant chaos. Grant outs himself as a traitor about five minutes after being recruited, a move that risks wrecking his own game almost before it has started. In a format that depends on secrecy, suspicion and strategic lying, that kind of slip is not a minor error. It changes the whole shape of the episode straight away.

Why this matters even if you do not watch The Traitors

Celebrity Traitors is the star-led version of the hugely popular competition series often summed up as a game of Mafia set in a Scottish castle. The cast brings together musicians, authors, journalists, comedians, actors and a few people who are famous for being famous. Some are secretly made traitors, while the rest are faithful, and much of the drama comes from whether the hidden players can keep their identities concealed.

That setup has already proved massive with viewers. The first celebrity season was the most popular show in the UK in 2025, with a live audience of more than 11 million. It featured figures including Alan Carr, Stephen Fry, Nick Mohammed and former rugby player Joe Marler. Season two returns with another packed lineup, and the faithful named early on include James Blunt, Michael Sheen, Rob Beckett, Romesh Ranganathan, Jerry Hall and Miranda Hart.

Season two has more than one source of early chaos

Grant's self-exposure is only one of the opening twists. This season begins with just two traitors, and they are quickly told to appoint a third. That is a change to the usual formula and gives the players more influence over how the game starts. The result of that pick is held for episode two, adding another thread of tension to a series that is already busy from the start.

The wider cast also looks ready to supply plenty of comic panic. James Acaster is part of the group, and Ross Kemp becomes a memorable presence in the first episode for a very different reason. Kemp, who is known for filming in active war zones and coming face-to-face with terrorists, is shown giving way to paranoia after Bella Ramsey puts a sailor's hat on his head and Leigh-Anne Pinnock touches his arm. For someone with that reputation, it is a strikingly small trigger, which only makes the moment more noticeable.

Grant's own explanation makes the moment stand out even more

Part of the reason Grant's wild start lands so strongly is that he seems genuinely delighted to be there. He speaks about advice from his wife, saying that four days before she died she told him to try to find a pocketful of happiness in each day. He says this experience feels like far more than that, describing it as a wheelbarrow-full and then some.

That sense of enjoyment gives his disastrous early reveal a different energy. Celebrity Traitors usually feeds on careful deception and slow-building distrust. Here, one of the best known names in the cast appears to blow a hole in the secrecy almost instantly. The opening episode does not even resolve the immediate fallout, because it ends before a single vote is cast at the round table. That leaves the audience waiting to see whether Grant's five-minute mistake has completely sunk him, or whether the show has found an even messier way to keep him in play.
