Black Bear and Artists Equity are teaming to add some rays to A Woman in the Sun, a new feature film project from Julia Cox that will star Academy Award winners Renée Zellweger and Sissy Spacek opposite Mia Threapleton.

Written and to be directed by Cox — in a reunion with Black Bear after a breakout moment penning the studio’s Nyad starring Annette Bening and Jodie Foster — A Woman in the Sun follows a month in the life of Claire Keating, to be played by Zellweger. While working as a bartender on Nantucket, part of the island’s dwindling middle class, Claire’s world cracks open when her mother gets sick and her daughter moves home. She is then forced to reckon with her past and take ownership of her future.

Production is slated to begin in September. The project will get tossed into the spotlight amid the Cannes Film Festival, during which time Black Bear will introduce it to international buyers. Black Bear and Artists Equity are co-financing, with Black Bear set to distribute in North America and the U.K. and in Canada via Elevation Pictures. Zellweger and Carmella Casinelli are producing through Big Picture Co. with Kim Roth and Greg Gertmenian set as co-producers.

“Championing promising filmmakers like Julia has been central to Big Picture Co.’s mission since day one, and we’re thrilled to be part of this very special project and the team who will help realize Julia’s vision. The script is a storytelling treasure, and Julia’s instincts set her apart as an emerging filmmaker. We can’t wait to get started,” said Zellweger, a two-time Oscar winner.

Artists Equity CEO Ben Affleck, an Oscar winner himself, shouted out the talents of Cox while revealing his company’s strategy for backing it. “Julia has proven herself as a writer, and I’m certain A Woman in the Sun will show the film world she’s equally gifted in the director’s chair. This is a moving, gripping exploration of a complex family dynamic with something lurking beneath the surface. And behind the scenes, we’ve got a tremendous partner in Black Bear. For us, this is about finding meaningful ways to invest in filmmakers at every stage of their journey, and projects like this are exactly the kind of work we want to be a part of. We’re looking forward to bringing this film to life.”

Added Black Bear CEO Teddy Schwarzman: “As soon as I met Julia, I knew she was destined to be an incredible director and working with her closely on Nyad only strengthened my belief in her as an artist and leader. With A Woman in the Sun, she has created that perfect vehicle to transition from acclaimed writer to world-caliber director. The story is both singular and universal, and Julia will no doubt capture unforgettably rich performances from Renée, Sissy and Mia. Black Bear is honored to back this powerful film alongside our good friends at Artists Equity, and we can’t wait to share it with audiences soon.”

In addition to Nyad, Cox also wrote and executive produced the upcoming film Love of Your Life directed by Oscar nominee Rachel Morrison and starring Margaret Qualley, Gabriel Basso, Aaron Pierre, Patrick Schwarzenegger and Catherine Keener. Cox is repped by CAA, Project D Media, Aloft Strateic Communications and the law firm Ziffren Brittenham.

Zellweger won Oscars for her work in Judy and Cold Mountain on top of nominations for Bridget Jones’s Diary and Chicago. She most recently starred in the latest installment in the Bridget Jones franchise, Mad About the Boy. She’s repped by CAA and Imprint PR.

Spacek has been nominated for six best actress Academy Awards. She won for her portrayal of Loretta Lynn in the 1980 hit Coal Miner’s Daughter. Her other nominations came for In the Bedroom, Crimes of the Heart, The River, Missing and a breakout role in Stephen King’s Carrie. She recently starred opposite Jennifer Lawrence in Lynne Ramsey’s Die My Love. Spacek is represented by UTA and MGMT Entertainment.

Threapleton is currently shooting Damien Chazelle’s untitled feature film. She had a breakout turn in Wes Anderson’s The Phoenician Scheme. Other credits include Karim Aïnouz’s Firebrand and Alan Rickman’s A Little Chaos. Threapleton is repped by CAA and Markham, Froggatt and Irwin.
