Mad Men's resident handsome bastard Jon Hamm is in talks to join Larry David in his upcoming, untitled, improvisational comedy.

David, of course co-created Seinfeld and currently cracks up the masses with his rather brilliant HBO series, Curb Your Enthusiasm. According to Showbiz411.com, Hamm would play David's nemesis in the film with David playing a "Larry David like character - but with a different name." Grand, so. Superbad and Adventureland helmer Greg Mottolla will call the shots, lending his deft comic touch to proceedings. The script will be extremely loose, and more of an outline - giving everyone room to stretch their creative muscles.

Hamm recently had an arc on 30 Rock that was very very funny; and if there's one thing David knows it's funny.
