Now, courtesy of Deadline, we know a lot more about the project. The film is titled "Clear History," and Jon Hamm and Michael Keaton have been confirmed as castmembers along with Bill Hader, Kate Hudson, Phillip Baker Hall, Danny McBride, Eva Mendes, Amy Ryan and JB Smoove. Alec Berg, David Mandel and Jeff Schaffer co-wrote the film with David.
"Clear History" is about Nathan Flomm (David), a former marketing exec at an electric car start-up who walks away from the company and his 10% share after a fight with the founder and head, Will Haney (Hamm). The company ends up being worth billions, to Flomm's humiliation, and with his personal and business life ruined, he ends up running away to live on an island off the Massachusetts coast under a new identity -- that of Rolly DaVore. But, naturally, his former boss ends up vacationing in the same place, driving David's character to seek revenge.
Hader will play a friend of Rolly's helping him in his quest, a man who works for an eccentric local quarry owner (Keaton). Hall will play Rolly's reluctant new boss, while Hudson has been cast as the wife of Rolly's rival. McBride, Mendes and Smoove will play locals, while Ryan is Rolly's ex. This film is supposed to start shooting this fall in Massachusetts.
David has done eight seasons of his half-hour comedy "Curb Your Enthusiasm" for HBO -- the most recent one ended in September of last year.
