Fox hopes to impart “The Rules for Starting Over” with viewers, developing a half-hour laffer about a group of suddenly single thirtysomethings.

Project comes from the Farrelly brothers, scribes Chris Pappas and Mike Bernier and producer Brad Johnson, through 20th Century Fox TV. The network has given the sitcom a script order. “Starting Over” will follow a 35-year-old guy who jumps back into the dating world after his marriage breaks up. The dude, along with his fellow divorced buddies, realizes that the rules of dating have changed while he has been off the market.

“Chris and I grew up together outside of Boston, and a lot of our friends got married right out of college,” Bernier said. “We noticed as a couple of these marriages weren’t working out, that these guys were heading back to the dating world in their 30s. And the rules of starting over in your 30s are very different.”

Johnson (through his Watson Pond Prods. label), Peter and Bobby Farrelly, Bradley Thomas and Kevin Barnett are on board to exec produce the single-cam comedy, while Pappas and Bernier will co-exec produce. The Farrellys’ Conundrum Ent. shingle is also attached.

Pappas and Bernier first brought the project to Johnson, whose shingle is set up at 20th. The trio then sold the project to 20th and brought the Farrellys (who worked with Pappas and Bernier on the feature script “Alcoholics Unanimous”) on board. Fox bought the script, with Bobby Farrelly attached to direct.

“We clicked with Brad at Watson Pond, and it was a chance to reteam with the Farrellys,” Bernier said.

Added Pappas: “All of these producers have writing experience, which was a great common denominator.”

Pappas and Bernier have spent most of their time in the feature world, with credits including “Brothers From Another Mother” at Fox Atomic and “Bridezilla” at Sony. Last season the duo first entered the TV biz, penning the pilot “Wing Men” at ABC.

As for the Farrellys, the brothers are also busy developing the pilot “I’m With Stupid” at NBC.

Pappas and Bernier are repped by CAA and manager Darryl Taja.
