Rob Lowe and Julia Ormond are set to star in Lifetime’s “Beach Girls.”

Based on Luanne Rice’s bestselling novel, the six-hour miniseries stars Lowe as a grieving widower who retires to a New England coastal community. Ormond plays a childhood friend of Lowe’s late wife — one of the titular “beach girls” — who gets drawn back into his life.

Mini is scripted by Edith Swensen, Elle Triedman and Eric Tuchman and will be produced by Robert Greenwald Prods. in association with Fox Television Studios. Greenwald and Alys Shanti (Lifetime’s “Plain Truth”) are serving as exec producers.

Chelsea Hobbs (“Lords of Dogtown”) and Chris Carmack (“The OC”) round out the cast as Jack’s daughter and a teen heartthrob, respectively.

Lowe recently wrapped the indie “Thank You for Smoking” opposite Aaron Eckhart, Robert Duvall and Katie Holmes. He’ll next be seen in the West End revival of “A Few Good Men,” by his former “West Wing” collaborator (and the series’ creator) Aaron Sorkin, at Royal Haymarket Theater.

Ormond recently appeared in HBO telepic “Iron Jawed Angels” with Hilary Swank, Anjelica Huston and Frances O’Connor. “Beach Girls” will mark her first appearance on an American TV series.

Mini will air over five consecutive Sundays, starting July 31.
