Duo developing drama about an open marriage

Showtime is developing an hourlong drama from “Bridges of Madison County” scribe Richard LaGravenese focused on an open marriage.

Drama centers on a suburban couple who get mixed results when they try to spice things up by meeting new friends.

LaGravenese, whose credits also include “P.S. I Love You,” “Freedom Writers” and “Paris, je t’aime,” will direct if the project goes to pilot. He’ll also serve as an exec producer, along with Stacy Rukeyser ( “Crash”), Clark Peterson, Dennis Erdman and Alexandra Milchan.
