text: Bradley, the only surviving five-star general officer in the United States after the death of Dwight D. Eisenhower in 1969, served as a consultant for the film though the extent of his influence and input into the final script is largely unknown. While Bradley knew Patton, it was also well known that the two men were opposites in personality, and there is evidence to conclude that Bradley despised Patton. As the film was made without Patton's diaries, it largely relied upon observations by Bradley and other military contemporaries when they attempted to reconstruct Patton's thoughts and motives. In a review of the film, Brigadier General S.L.A. Marshall, who knew both Patton and Bradley, stated, "The Bradley name gets heavy billing on a picture of [a] comrade that, while not caricature, is the likeness of a victorious, glory-seeking buffoon.... Patton in the flesh was an enigma. He so stays in the film.... Napoleon once said that the art of the general is not strategy but knowing how to mold human nature.... Maybe that is all producer Frank McCarthy and Gen. Bradley, his chief advisor, are trying to say."
  Filming
  The film started shooting February 3, 1969 and was shot at seventy-one locations in six countries, mostly in Spain, which had a lot of the U.S. Army's World War II surplus equipment.
  Francoist Spain had sustained a currency control for decades and filming in the country was the only way to indirectly recover the profits of the box office from American films.
  Cheap labor also encouraged runaway productions.
