Greg Mottola‘s schedule is quickly filling up. Earlier this week, the Superbad helmer signed on to adapt the Jeffrey Eugenides novel The Marriage Plot for producer Scott Rudin. Now he’s entered talks to helm something completely different: an untitled comedy for Fox Searchlight, with Curb Your Enthusiasm creator/star and Seinfeld co-creator Larry David in negotiations to star. More details after the jump.

The plot of the new film is being kept under wraps for now, but we do know that it will be partially improvised a la Curb Your Enthusiasm. THR reports that David came up with the idea himself and has already begun hashing it out with co-writers Alec Berg, Jeff Schaffer, and David Mandel, who’ve previously worked with David on Seinfeld and Curb Your Enthusiasm. In addition, the trio are just coming off of Sacha Baron Cohen’s The Dictator, so they should have a pretty good (pretty, pretty, pretty good) idea of how to handle a semi-improvised storyline like this one. All four men are set to produce, along with Bradley Thomas.

Although David has enjoyed a successful career in television for three decades, with Seinfeld and Curb Your Enthusiasm as his crowning achievements, he has only made very occasional forays into film. His only big-screen leading role to date was in Woody Allen’s 2009 comedy Whatever Works. More recently, he made a cameo appearance in the Farrelly brothers’ The Three Stooges, playing Sister Mary-Mengele.

While Mottola isn’t quite as experienced with David’s style of semi-improv, he has a strong comedy background, having helmed episodes of shows like Undeclared and Arrested Development and movies like Superbad and Paul. As of yesterday, Mottola was eyeing the possibility of directing The Marriage Plot, but with this new comedy on his plate we’ll have to see how the timing works out. Both projects sound very promising, so here’s hoping he can somehow make room for both.
