I have a working theory that whenever an actor signs up for a crime drama (as of last year) on BBC iPlayer, they automatically get offered a spot on The Celebrity Traitors.
Think of the fact that every series of Strictly Come Dancing has one contestant from EastEnders and Gladiators alike — almost like TV channel conscription. Now that The Traitors has been renewed until 2030, maybe it will even be added to people's contracts.
