First Look: See Larry David and Jon Hamm in HBO's new film, 'Clear History' -- EXCLUSIVE VIDEO

Recognize the guy on the right?

That’s a virtually unrecognizable Larry David in the new HBO movie Clear History (due in August). David stars as Nathan, a hipster marketing exec who sells all his shares at a start-up over a fight with his boss (Jon Hamm, left), only to miss out on billions when the company’s new product—an electric car—becomes a smashing success.

“It ruins his life,” says director Greg Mottola (Superbad), who explains that the comedy then picks up a decade after a humiliated Nathan changes his name and goes incognito.
