UPDATED: Warners picked up the project about a year ago with Tom Cruise as its probable lead actor.

Ben Affleck is attached to star in Nathan Decker, a political comedy that Warner Bros. is developing as a star vehicle.

Warners picked up the script by Dan Fogelman (Crazy, Stupid, Love) about a year ago with Tom Cruise as its probable lead actor. Cruise has since fallen off the project, so Warners approached Affleck. The studio is looking to hire a director.

The story centers on a politician who is caught in an affair and returns to his hometown to confront his past.

Affleck will not direct the film. He is in postproduction on the Warners thriller Argo. He most recently starred in 2010's The Town, which he also directed and co-wrote.

Fogelman also wrote The Guilt Trip (previously titled My Mother's Curse), the upcoming Seth Rogen-Barbra Streisand road-trip comedy from Paramount.
