Sarah Jessica Parker is in “A Fair Marriage,” coming onboard to produce the feature as a potential starring vehicle through her Pretty Matches banner with partner Allison Benson along with Maven PicturesTrudie Styler and Celine Rattray.

Playwright Daniel Goldfarb (“Modern Orthodox,” “Martin Short: Fame Becomes Me”) is penning the script. Hardy Justice, senior VP of production/development for Maven, brought the project to Styler and Rattray.

“A Fair Marriage” will center on a woman six years into her marriage. She rediscovers who she is, what she is capable of and how deep her love for her family runs — by becoming someone else.

Styler and Rattray wrapped Maven’s first film, “Imogene,” starring Kristen Wiig and Annette Bening, in New York on Sept. 17. They said that Parker, Benson and Goldfarb are the sort of New York-based talent with whom Maven hopes to partner.

“And we love supporting female-driven material, which just adds to the excitement,” the duo said.

New York-based Maven finances development and provides equity for films across a wide range of budgets and aims to produce three to five pics per year.

“Imogene,” which also stars Matt Dillon and Darren Criss, was written by Michelle Morgan and directed by Shari Springer Berman and Robert Pulcini. Story concerns a New York playwright who stages a fake suicide attempt to win back her ex-boyfriend, only to end up being forced into the custody of her gambling-addict mother.

Pretty Matches, founded by Parker, has an overall production deal with HBO and numerous projects in development at the network along with “Work of Art: The Next Great Artist” on Bravo.

Parker stars in “I Don’t Know How She Does It” and will be seen next in “New Year’s Eve.”
