Comedies rarely provoke genuine laughter, but “Last One Laughing UK” succeeds effortlessly, even though the premise centers on not laughing. Returning for its second season on Prime Video with a fresh cast, this game show/reality TV competition hosted by Jimmy Carr features 10 comedians confined to a room for six hours. The singular rule? Laugh twice, and you’re eliminated. The last remaining participant claims victory.

What’s the premise of “Last One Laughing UK”? The guidelines are straightforward, but many surprises await. Season 2 showcases comedians such as David Mitchell, Mel Giedroyc, Alan Carr, Romesh Ranganathan, Amy Gledhill, Maisie Adam, Gbemisola Ikumelo, Sam Campbell, Diane Morgan, and Bob Mortimer. They are enclosed in a spacious set complete with a kitchen, lounge area, and performance stage. At any moment, Carr and co-host Roisin Conaty can summon any participant to utilize their “joker” card, resulting in a brief, often absurd performance while the others observe.

In addition to the jokers, the program features an array of tasks, challenges, and unexpected events, crafting a dynamic variety show with everyone perpetually on the brink of laughter.

“Last One Laughing UK” is an ideal choice for enthusiasts of “Taskmaster.” If you’re familiar with “Taskmaster,” you’ll grasp the essence of “Last One Laughing UK.” While the challenges aren’t as unpredictable as those in Alex Horne’s series, they retain a similarly whimsical and surreal essence. Season 2 includes Bob Mortimer engaging in an arm wrestling match with David Mitchell, Maisie Adam confronting Romesh Ranganathan over their most significant regrets, and Sam Campbell along with David Mitchell bellowing as they approach one another.

The prohibition against laughing injects a frenzied energy into each moment, with an ever-present tension amplified by reaction shots of those attempting to suppress their smiles.

In Season 2 of “Last One Laughing UK,” there are some fantastic surprise appearances. Season 1 featured guests like Danny Dyer, Alison Hammond, and Nick Mohammed. Season 2 continues this trend with surprises, including British presenter Richard Madeley interviewing the cast with dry, deadpan inquiries.

The drawback? Season 2 consists of only six 30-minute episodes, which pass swiftly. The silver lining? Five episodes are available, and the finale premieres on Thursday, providing an opportunity for a binge-watch before the champion is declared. “Last One Laughing UK” Season 2 is currently streaming on Prime Video, with the concluding episode set to air on Thursday.
