Octavia Spencer has joined Kevin Costner in Mike Binder’s indie drama “Black and White.”

IM Global has come on board to rep international rights and will launch sales next week  in Cannes. Production is set to start in New Orleans this summer.

“Black and White” is a co-production of Costner’s Treehouse Productions and Binder’s Sunlight Productions, along with Todd Lewis. Cassian Elwes is exec producing and handling the U.S. rights.

Binder is directing from his own script, focusing on an attorney (Costner) who is widowed after the car crash death of his wife and finds himself embroiled in a custody battle over his biracial granddaughter. Spencer will portray the grandmother of the child

“We’re delighted to come onboard such a powerful, compelling project with the Costner/Binder team that memorably brought us ‘The Upside of Anger,'” said IM Global CEO Stuart Ford said. “Kevin’s recent critical achievements as both an actor and producer with ‘Hatfields & McCoys’ give the project added momentum.”

The deal was brokered by Elwes on behalf of the producers, and by Ford and IM Global president Jonathan Deckter.

Spencer is repped by WME.
