Before “They Call It Pro Football” premiered, football films were little more than highlight reels set to the oom-pah of a marching band. In 1964, National Football League commissioner Pete Rozelle agreed to the formation of NFL Films. With a background in public relations, he recognized that the success of the league depended on its image on television, which required creating a mystique. “They Call It Pro Football,” the first feature of NFL Films, looked at the game “in dramaturgical terms,” capturing the struggle, not merely the outcome, of games played on the field. Written and produced by Steve Sabol, directed by John Hentz and featuring the commanding cadence of narrator John Facenda and the music of Sam Spence, the film presented football on an epic scale and in a way rarely seen by the spectator. “They Call It Pro Football” established a mold for subsequent productions by NFL Films and has well earned its characterization as the “Citizen Kane” of sports movies.
