Larry David is looking for a nemesis for the new improv film he starts shooting in the fall. And Jon Hamm is answering the bell.

Hamm, who has proven not only adept but masterful on “30 Rock” and “Saturday Night Live,” will square off with David in the new, as-yet-unnamed film. Reports indicate that David will play a…well…Larry David-like character that finds himself in awkwardly hilarious situations, a la “Curb Your Enthusiasm” (hey, if it ain’t broke…).

Hamm will reportedly serve as David’s sparring partner, which we think could very well be a match made in improv heaven, especially after Hamm held his own in the recent live episode of “30 Rock.”

The project is still in the planning stages, although we know Greg Mottola is directing and Fox Searchlight has gotten the rights to distribute the film.

Meanwhile, in other Larry David news, the “Seinfeld” co-creator is joining a passionate and boisterous celebrity campaign to create one million national service jobs to help stimulate the job market for young Americans.

"Sign the petition to create a million jobs, or I will come over there and slap you silly," David says in a new video promoting a petition being circulated by the non-profit group Our Time.

See? Larry does more than be utterly hysterical.

J-Connection: Larry David is really, really Jewish. Jon Hamm is really not…but with a last name like his, wouldn’t it have been sweetly ironic if he were?
