Robbie Williams couldnt do it, but maybe Taskmaster will? The comedy shows attempts to break America continue with the second US launch event at which a new Taskmaster episode premiered ahead of its UK debut. Following on from 2024s series 17 NYC event, series 19 was unveiled for the first time last night at New Yorks Town Hall. No UK air date has yet been confirmed but its not expected to arrive on Channel 4 until March.Despite huge success in the UK, Taskmaster has so far found America a tough nut to crack. The 2018 Comedy Central US version hosted by Reggie Watts and Alex Horne failed to catch on and was quickly cancelled. In 2020, the CW bought in episodes to fill the lockdown-based content vacuum but only showed a few before low numbers took it off air. Now, a well-known US comedy star, teased in advance as a big-name American, has been cast in series 19.That star is comedian, actor and podcaster Jason Mantzoukas. As announced at the NYC series 19 launch event, hell be joined by actor-writer Mathew Baynton, sketch comedian Stevie Martin, stand-up Fatiha El-Ghorri, and presenter and podcaster Rosie Ramsey.

Hes also one third of the presenting team on podcast How Did This Get Made?, alongside June Diane Raphael and Paul Scheer. A bit of an anglophile, Mantzoukas immersed himself in British pop culture during his time filming on Taskmaster, as explored on his Off Menu podcast episode with Taskmaster podcast host Ed Gamble. Mantzoukas is a rare overseas Taskmaster contestant who filmed his segments on a visit to the UK rather than being based in the United Kingdom like fellow non-Brit Taskmaster alumni Katherine Ryan, Desiree Burch, Rose Matafeo, Sarah Kendall, Mae Martin and Sam Campbell.Rosie RamseySix series after her husband Chris Ramsey appeared on Taskmaster, podcaster and TV presenter Rosie Ramsey will be donning the blue jumpsuit to muck in herself.
