Robin Wright Penn, Julianne Moore and Wynona Ryder will star in drama-comedy “The Private Lives of Pippa Lee,” produced by Elevation Filmworks and Plan B Entertainment.

Lemore Syvan of Elevation will produce along with Plan B. London-based Lumina Films is co-producing and handling worldwide sales, with CAA partnering on the sale of domestic distribution rights. Lumina will introduce the film to international buyers at the upcoming AFM in Santa Monica.

Rebecca Miller (“The Ballad of Jack and Rose”) is directing from her novel of the same title. Story centers on a dutiful wife whose husband falls for a younger woman, freeing her to explore her buried sensuality and leading to a “a very quiet nervous breakdown.”

Lensing is scheduled to start in April in Connecticut.

Elevation and Syvan produced family drama “Gracie” and “The Ballad of Jack and Rose.” Plan B is a producer on “The Assassination of Jesse James by the Coward Robert Ford.”
