Diana Ossana (“Brokeback Mountain”) is writing and producing a feature adaptation based on the inspirational tome “Hope’s Wish.”

Fixed Point Films’ Jonah Hirsch and Shining Star Prods.’ Stuart Stout are developing, financing and producing “Hope’s Wish,” with Ossana set to begin work on the project this fall.

Exec producers are Larry McMurtry, Stuart Stout, Bert Hesse and Stephen Bridgewater. McMurtry and Ossana won an Oscar for “Brokeback Mountain” in adaptating Annie Proulx’s story.

“Hope’s Wish: How One Girl’s Dream Made Others Come True” was published in 2008 and written by Stuart and Shelby Stout about their daughter after she was diagnosed with a life-threatening illness at age 12. She spent her remaining time helping raise funds for the Make-A-Wish Foundation.

“?’Hope’s Wish’ reminded me of the innocence of children and their refusal to accept the limits of what adults consider might be possible,” Ossana said.

Los Angeles-based Fixed Pont Films has produced “Main Street,” starring Colin Firth, Orlando Bloom and Ellen Burstyn, and “Passion Play” starring Mickey Rourke, Megan Fox and Bill Murray.

Ossana and McMurty are represented by UTA, Anonymous Content, Greg Redlitz and Robert Thorne.

The project has the cooperation of the March Forth with Hope Foundation, the charitable org set up by the Stout family along with Make-A-Wish.
