Julia Roberts will produce a feature adaptation of Lolly Winston’s bestselling novel “Happiness Sold Separately,” with an eye to star in the pic.

Scott Coffey (“Ellie Parker”) will direct and adapt.

Fox Searchlight is in talks to distribute “Happiness,” with Team Todd’s Suzanne and Jennifer Todd and Joe Roth producing along with Roberts through her Red Om shingle. Valeska Ramet, who brought the book to Coffey, will also produce.

“Happiness Sold Separately” is centered on a suburban wife and her withdrawal from her husband as he begins an affair with the nutritionist at their gym.

Coffey said, “I couldn’t get Julia out of my head when I was reading Lolly’s book. Elinor is such a strong, complicated woman, and bringing her to the screen required Julia’s integrity, empathy, humor and legs.” 

Roberts is in production on Universal’s “Charlie Wilson’s War” and is voicing the title character in “Charlotte’s Web.” She’s attached to star in and produce “The Friday Night Knitting Club” for U and Christine Peters, and is developing a feature based on the American Girl doll characters with Walden Media and Elaine Goldsmith-Thomas.

Coffey penned “K-Town Super Frog” for Anonymous Content, an adaptation of Haruki Murakami’s “All God’s Children Can Dance.” He’s adapting Andy Greenwald’s novel “Miss Misery” for the Jacobson Co. and will also direct.

Roberts is repped by CAA and Hirsch Wallerstein Hayum Matlof and Fishman. Coffey is repped by Anonymous Content, Innovative Artists and Linda Lichter at Lichter, Grossman, Nichols & Adler. Winston is repped by Joel Gotler.
