Dara O Briain is to feature in a new Sky Atlantic comedy series called Set List, alongside a host of comedians, including Robin Williams.
The entertainment programme takes the form of a fully improvised stand-up show in front of a live audience, with comics inventing material based on topics presented to them while on stage.
Tim Minchin, Ross Noble, Drew Carey, Frank Skinner and Russell Kane are among the other comedians signed up to appear on the series.
Each episode will see three stars take to the stage, tackling themes devised by comedian Paul Provenza and series creator Troy Conrad.
Acting Director of Sky Atlantic Naomi Gibney said of the show: "A key part of our commissioning strategy for Sky Atlantic has been to attract the best talent to the channel...
"Set List really illustrates that ambition, and I can't wait to see how they live up to the challenge."
Philip Edgar-Jones, Sky's Head of Entertainment, added: "Set List is a uniquely terrifying approach to stand-up comedy. I love it because we have no idea what we'll get.
"It's like a bizarre compulsion to some of the biggest names in stand-up who are addicted to the freedom it brings them to take their comedy anywhere and everywhere."
Sky Atlantic has ordered 14 episodes of Set List to be made.
