Development of a documentary based on Simpson for
ESPN Films began in 2007, eventually leading to the hiring of
Brett Morgen to create the film,
June 17th, 1994, also part of the
30 for 30 series. Throughout the 18-month process from conception to completion, Edelman conducted 72 interviews for the documentary, "including key players from the prosecution (
Marcia Clark,
Gil Garcetti and
Bill Hodgman), Simpson's defense team (
F. Lee Bailey,
Carl E. Douglas and
Barry Scheck), childhood friends of Simpson (Joe Bell and Calvin Tennyson), relatives of Simpson (cousin Dwight Tucker), fellow football players (
Jim Brown and
Earl Edwards), jurors from the criminal trial (Carrie Bess and Yolanda Crawford), former LAPD detectives involved in the case (
Mark Fuhrman and Tom Lange) and African-American civil rights activists (
Dr. Harry Edwards,
Danny Bakewell and
Cecil Murray)", and people who could speak on behalf of Ron Goldman (his father Fred Goldman) and Nicole Brown Simpson (her sister Tanya Brown, her friends David LeBon and
Robin Greer, and her boyfriend Keith Zlomsowitch). Also interviewed were people connected to Simpson such as his agent
Mike Gilbert along with Tom Riccio and Bruce Fromong, who were each involved parties of the 2007 robbery. Edelman also reached out to Simpson through a letter, which was never answered; he had also hoped to include Simpson's first wife, Marguerite L. Whitley, who could not be contacted, and former L.A. County district attorney
Christopher Darden, who declined participation. (He would later appear in the 2025
Netflix docuseries
American Manhunt: O.J. Simpson). Despite envisioning the project as a five-hour documentary, the final film was screened to ESPN Films executives at 7.5 hours in length, to which Schell said they would figure out the programming end, as they were "going to give Ezra the time he needs to tell this story". In January 2016, ESPN Films announced
O.J.: Made in America for part of their
30 for 30 series. == Music ==
