Director David Anspaugh and script writer Angelo Pizzo were unhappy with studio executives, who cut their budget from $65 million to $27 million. Thus, the film's running time had to be reduced from almost 2 hours 10 minutes to 1 hour 41 minutes. Some notable exclusions were Frank "Pee Wee" Wallace as a German POW and an emotional scene of "America as a melting pot" in which the players go to Ellis Island and look up records of their ancestors. Pizzo said that only 45-50% of what he intended to be in the movie actually made it into the final cut.
