Last One Laughing UK S3 Cast Revealed 2027

Halloween special details: Last One Laughing Halloween will be a four-part event airing across late October 2026 (first three episodes on October 23, final episode on October 30), featuring Jack Dee, Phil Wang, Reece Shearsmith, Harriet Dyer, Tom Allen, Lou Sanders and Daisy May Cooper.
David Mitchell, the Season 2 winner, will not return for Last One Laughing UK Season 3, signaling a shift in the competition dynamics as the new run moves forward with a different contestant lineup.
Lou Sanders and Daisy May Cooper are highlighted as returning performers for the Halloween special, reinforcing the cross-season special feel of Last One Laughing and its tradition of star cameos.
Prime Video has unveiled the full cast for Last One Laughing UK season 3, arriving in 2027 with a fresh 10-comedian lineup that includes Lee Mack, Katherine Ryan, Harry Hill, Katherine Parkinson, Michelle de Swarte, Jon Richardson, Morgana Robinson, Josh Jones, and Richard Ayoade, according to Yahoo News.
The season brings a major format shake-up: Roisin Conaty will leave her role as Jimmy Carr's deputy in the control room to compete as a contestant, while Mel Giedroyc takes over Carr's deputy position. Meanwhile, a Halloween special will air in late October 2026 featuring Jack Dee, Phil Wang, Reece Shearsmith, Harriet Dyer, Tom Allen, Lou Sanders, and Daisy May Cooper, AOL reports.
Roisin Conaty's shift from behind-the-scenes deputy to on-stage contestant marks the biggest format change for Last One Laughing UK yet. She spent the previous seasons helping Jimmy Carr run the control room, managing the action from above. Now she'll face the same pressure as the other nine comedians trying to keep a straight face under attack, according to The Telegraph and Argus.
Mel Giedroyc fills the deputy role Conaty vacates, stepping into the control-room hierarchy. This reshuffle adds fresh dynamics to the show's two-layer structure—where contestants compete on stage while the control room orchestrates comedy assaults from above.
David Mitchell, who won Last One Laughing UK season 2, will not return for the third series. Lancashire Telegraph confirmed that the competition is moving forward without him, signaling a shift in the show's approach to returning champions.
Richard Ayoade, the season 1 runner-up, provides continuity by returning as a full contestant. His presence gives the new season a built-in reference point for viewers who watched the show's early runs.
Before the main season launches, Last One Laughing will air a four-part Halloween special in October 2026. The first three episodes drop on October 23, with the finale on October 30. Keighley News reported the special will feature Jack Dee, Phil Wang, Reece Shearsmith, Harriet Dyer, Tom Allen, Lou Sanders, and Daisy May Cooper.
Lou Sanders and Daisy May Cooper are among the returning performers, reinforcing Last One Laughing's tradition of cross-season cameos and guest appearances that keep the format fresh.
Despite the cast changes, Last One Laughing keeps its fundamental premise intact: ten comedians try to survive rounds of comedy attacks without cracking a smile or laughing. Jimmy Carr remains as the ultimate arbiter from his control room position.
The show promises additional comedy cameos, twists, and surprises as it evolves. Season 3 is expected to follow the established March launch pattern from previous seasons, maintaining the show's regular release schedule while introducing fresh personalities and unexpected format shifts.
