As the Just For Laughs festival gears up for its 40th anniversary, the world of comedy is abuzz with excitement. And, this year, one of the biggest names in late-night television is making his debut on the iconic Montreal stage: David Letterman. The legendary host of 'The Late Show' and 'Late Night' is set to bring his 'An Evening With David Letterman' series to the festival, and we've got the scoop on his exclusive interview guest: none other than Will Arnett.

For fans of Letterman's irreverent humor and Arnett's scene-stealing antics, this is a match made in heaven. Arnett's latest Netflix special, 'Is This Thing On?', has been making waves with its hilarious take on life, love, and career struggles. And, as the master of quick-witted banter, Letterman is sure to dig deep into Arnett's psyche, uncovering the funny – and not-so-funny – stories behind the Canadian comedian's career. This is more than just a Q&A, folks – it's a chance to see two comedy legends trade barbs and share laughs in a conversation that's sure to leave the audience in stitches.

But, what's behind Letterman's decision to bring this show to Just For Laughs? Sources close to the project reveal that the former 'Late Show' host has long been a fan of the festival, which has a reputation for showcasing the best of the best in comedy. 'David's always been a huge supporter of emerging talent,' says a friend of the host. 'He's thrilled to be a part of the JFL lineup and can't wait to share the stage with Will.' And, with Arnett's star on the rise, it's the perfect opportunity for Letterman to tap into the excitement surrounding the 'BoJack Horseman' and 'Arrested Development' veteran.

This special event also marks a significant moment in the festival's history, as it celebrates its 40th anniversary.
