Trivia: John Wayne had been wanting to do this picture for years but he could not get any backing. He finally used his own money and he felt the financial setback for years, because the picture did not do as well as expected. Duke would always say that he had to continue to work and make pictures to survive. He was nowhere near broke, but to keep up his lifestyle he worked almost to his death.
