Lee Mack is in the 10-comedian line-up for Last One Laughing UK season 3, with Prime Video setting the new series for 2027. Jimmy Carr will host again, while Richard Ayoade returns after narrowly missing out on winning in season 1.
Ten comics, one host
The season 3 line-up also includes Katherine Ryan, Harry Hill, Katherine Parkinson, Michelle de Swarte, Jon Richardson, Morgana Robinson and Josh Jones. That makes 10 comedians in the cast, with Roisin Conaty also joining the competition and Mel Giedroyc stepping in as Jimmy Carr's deputy.
Last One Laughing UK works as a competition built around comedians trying not to laugh, so the value of the cast is in how many familiar styles it can throw into the same room. Lee Mack's addition keeps the line-up anchored by a mainstream panel-show presence, while the rest of the booking mixes stand-up, character work and improvisation-ready names.
Richard Ayoade returns
Richard Ayoade is the complication in the line-up. He is back after narrowly missing out on winning in season 1, which means season 3 is not just a fresh cast list but a partial reunion of a performer who already knows the format from the inside.
That return matters because the source does not say whether any other former contestants are back, so the new series leans on one returning player rather than a full rematch. For viewers, that suggests season 3 will still hinge on how well the newcomers read the room once the pressure starts.
Halloween special on 23 October
A Halloween special arrives before the 2027 launch of Last One Laughing UK season 3. It is a four-parter, with the first three episodes dropping on Friday 23 October and the final episode landing on 30 October.
That split release gives Prime Video two separate runs to market: the Halloween special now, then the full third season later. The practical takeaway is simple — Lee Mack is part of the next main season, but the nearer release is the four-part Halloween special beginning on 23 October.
