A fresh group of comedians is getting ready to face one of TV’s toughest challenges, and Prime Video has now revealed who’ll be trying to keep a straight face in the next series.
Last One Laughing UK Reveals Full Series Three Cast

Last One Laughing UK will return for its third series early next year, with Jimmy Carr back as host. Lee Mack and Harry Hill are among the 10 comedians taking part, alongside Katherine Ryan and Jon Richardson.
Katherine Parkinson and Michelle de Swarte are also joining the line-up, with Morgana Robinson and Roisin Conaty completing another part of the cast. Josh Jones will make his debut, while series one runner-up Richard Ayoade returns to see whether he can go one better this time.
The rules remain simple: the comedians must spend the day trying to make each other laugh without cracking a smile themselves. We can also expect surprise appearances and new twists designed to catch the contestants off guard.
Before the third series arrives, we’ve got the Last One Laughing Halloween special to look forward to in October. That edition will bring back Lou Sanders and Daisy May Cooper for a spooky version of the challenge.
Prime Video has yet to confirm an exact release date for series three, but it’s expected to arrive in early 2027
