Henry Hathaway, considered along with Otto Preminger, as the most difficult director in the business to work with because of his nasty behavior with the actors and technicians, harassed, as usual, the crew and Gregory Peck had to interfere to protect them from the director's wrath. Hathaway was very deferential with his star. However, years later, Hathaway insisted that Peck had been all wrong for the part and had only been hired at the insistence of producer Hal Wallis - and also that this miscasting had ruined the film.
When Clay (Gregory Peck) is helping Decky (Dawn Lyn) off her horse at the deserted ranch, he calls her Scout, which was the name of Peck's daughter in To Kill A Mockingbird.
Suzanne Crough (who played Tracy on "The Partridge Family") auditioned for the role of Decky Ortega, but "The Partridge Family" producers wouldn't let her do It, so the role went to Dawn Lyn.
