Larry David is ready to wash the taste of 2009’s Whatever Works out of your mouth: He’ll return to the big screen in a not-yet-titled comedy directed by Greg Mottola (who’s having a big week, nearing an adaptation of Jeffrey Eugenides’s The Marriage Plot) and written by Alec Berg, Jeff Schaffer, and David Mandel, whom David teamed with on Seinfeld and Curb Your Enthusiasm both. Plot details are nonexistent, but it’ll be “improv-based.” Curb: The Movie?
