Would play opposite Larry David, Jon Hamm in electric-car comedy

Michael Keaton is in talks to join Larry David and Jon Hamm in Greg Mottola’s untitled Fox Searchlight comedy.

While Fox Searchlight did not immediately respond to inquiries, Keaton confirmed his casting in an interview with ESPN’s pop-culture site Grantland.

David came up with the idea for the pic and tapped his trusted “Seinfeld” and “Curb Your Enthusiasm” scribes Alec Berg, Jeff Schaffer and David Mandel to write a treatment with him, though the film itself will feature an improv-based storyline.

Plot is said to involve David and Hamm as characters who each invest in an electric-car company with different goals in mind. When the car becomes a success, David’s character gets his investment back, while Hamm’s businessman becomes extremely rich, causing tension between the duo. Keaton is being recruited to play a crazy businessman named Stumpo, who is David’s friend.

David and Bradley Thomas will produce the pic with Berg, Schaffer and Mandel, who recently produced “The Dictator,” which they co-wrote with star Sacha Baron Cohen.

Keaton first met David when they were doing standup early in their careers. Thesp recently appeared in Adam McKay’s cop comedy “The Other Guys” and voiced the Ken doll in Disney-Pixar’s “Toy Story 3.” He’ll soon be seen as the villain terrorizing Michelle Monaghan in Joseph Ruben’s indie thriller “Penthouse North.”

Keaton is repped by ICM Partners.
