EXCLUSIVE: A Darren Star-produced dramedy has become a hot property with three networks vying for it. I hear ABC, NBC and CBS are all after Good Christian Bitches, which will be written by Steel Magnolias and The First Wives Club scribe Robert Harling. Based on the book of the same name by Kim Gatlin, the project, referred to by some as “Desperate Housewives in Dallas,” centers on Amanda Vaughn, a recently divorced mother of two who, to get a fresh start, moves back to the affluent Dallas neighborhood where she grew where she finds herself in the whirling midst of salacious gossip, Botox, and fraud. Harling, Star and Aaron Kaplan are executive producing. Harling has been mostly focused on features, with the exception of a 1990 Steel Magnolias CBS pilot he wrote based on his play and the movie, which he also penned. On broadcast TV, Star, creator of Sex and the City, Beverly Hills, 90210 and Melrose Place, most recently executive produced the ABC dramedy Cashmere Mafia.
