This was Rita Hayworth's last completed movie. She had difficulty remembering her lines. The crew believed it was because of alcohol abuse, but only later did they realize they were seeing the early stages of her Alzheimer's condition. Fittingly, it was one of the few times after becoming a star that she played her actual heritage.
One night during production when the film company was based in Mexico City, publicist Tom Miller dined out with Rita Hayworth. When they got back to her hotel, there was much excitement. The Mexican equivalent of the Academy Awards were being presented in the large convention hall in the hotel. Rita was tuned on. "Let's go!" Rita said. Miller replied, "But Rita, we don't have an invitation!" She looked back at him and said, "But I am Rita Hayworth!" And Miller said, "So you are." He spoke to someone at the door, who excitedly ran up to the front of the room and whispered to the MC, who announced to the crowd the presence of a surprise guest. And she went up on the stage to a standing ovation.
Production on the movie stopped Dec. 23, 1971, after Ken Hutchison had an accident in his hotel room with his hand through a pane of glass. After debate whether to replace him and re-shoot, he recovered sufficiently by mid-January to continue.
According to the film's review in the 6 September 1972 edition of the Los Angeles Times, the American Humane Association alleged the horses were abused in this picture.
Although he has the actual leading role and is in almost every scene, Ken Hutchison only received sixth billing, as he was virtually unknown in the U.S. at the time.
