A movie about the University of San Francisco 1951 Dons football team is in development at Walden Media and Mandalay Sports Media.

Mike Tollin in producing for Mandalay. The project is being written by Isaac Adamson about the undefeated football team that turned down a bid to play in the Orange Bowl in Miami after being told that the team would not be allowed to use its two black players — running back Ollie Matson and linebacker Burl Toler. The team unanimously voted to decline the invitation.

The team’s defensive star Gino Marchetti told the New York Times in 2009, “We answered, ‘No, we’d never do that.’ And after we said no and removed ourselves from consideration, nobody ever had a second thought about it.”

The team lost $70,000 over that season. With no bowl money to offset the deficit, the university discontinued its football program.

Naia Cucukov will oversee the project on behalf of Walden Media, which produced “Everest” and is in post-production on Steven Spielberg’s “The BFG.”

Mandalay Sports just completed production on boxing drama “The Bleeder,” starring Liev Schreiber.

Adamson’s Michael Jackson script “Bubbles” was the top project on the 2015 Black List this week. He is represented by CAA and manager Lee Stobby.

The news was first reported by Deadline Hollywood.
