Berg says ‘So’ for Fox, Conundrum

Farrelly brothers set to produce

Actor-writer-director Peter Berg, who made his feature directorial debut on the blood-soaked black comedy “Very Bad Things,” has signed to helm “Say It Isn’t So” for 20th Century Fox and Conundrum Entertainment.

Peter and Bobby Farrelly and Bradley Thomas will produce under their Fox-based Conundrum banner.

The comedy is about a down-on-his-luck, lifelong bachelor who finally finds the love of his life, only to discover (erroneously) that the woman is his sister.

Peter Gaulke & Gerry Swallow penned the screenplay. Gaulke & Swallow also are writing the animated feature “Frisco Pigeon Mambo” for Conundrum and Fox Animation Studios.

Exec VP Hutch Parker is overseeing the pic for Tom Rothman’s Fox film division.

With Berg onboard, Fox has begun casting “Say It Isn’t So,” with an eye toward an August start.

Berg, who is winding down his run on the CBS drama series “Chicago Hope,” should get word this week whether “Bellevue,” the series he created, will be picked up by ABC for next season.

Berg wrote and directed the pilot for the drama set in a New York psychiatric hospital.

Berg’s “Very Bad Things,” starring Christian Slater, Cameron Diaz and Jon Favreau, was released earlier this year by Polygram Films. Berg is repped by Endeavor.

The Farrellys are lensing “Me, Myself and Irene,” a multiple personality farce starring Jim Carrey, also for Fox and Conundrum.
