Prior to filming, Arizona State Prison Warden Robert Raines had tried to organize a rodeo for 2 years. The biggest obstacle was the cost of constructing an arena, complete with grandstand, stables, and livestock chutes. When Columbia Pictures inquired about renting the prison for a film shoot, he saw a way to realize his dream. If security could be maintained, the prison was available for a fee which matched the budget for the new rodeo grounds. Raines said, "There was a fringe benefit we didn't anticipate. Morale in the prison was never higher. Some 350 inmates signed on as extras, playing themselves, and the rest, even the most notorious troublemakers, stayed on their best behavior. There were simply no incidents."
