David Wain’s film about National Lampoon co-founder Doug Kenney just keeps getting more exciting. Will Forte will star as Kenney, Joel McHale will play Chevy Chase, Domhnall Gleeson will play Henry Beard, and today The Hollywood Reporter has revealed that Thomas Lennon has signed on to play Lampoon editor and SNL’s first head writer Michael O’Donoghue. The film is slated to begin production later this month and is based on Josh Karp’s 2006 book A Futile and Stupid Gesture.
