According to an AP report from May, 1954, Piper Laurie was a replacement for original leading lady, Allison Hayes. No reason was given for the change, but Hayes left Universal-International about the same time.
According to Piper Laurie in her memoirs "Learning To Live Out Loud," Dana Andrews was almost always drunk between filming sequences, but remained very professional on the set.
A United Press item dated 10 June 1954, described a peculiar problem that Universal-International Studios was having filming in the Southern Utah town of Moab. Director Jerry Hopper said that he couldn't secure extras on location in a community hit by uranium fever, observing that Moab residents "would rather go out in the hot desert looking for uranium than get paid $15 a day to just stand around as extras."
In May 1954, it was reported the producers had pushed back the start of production in the hopes of getting Charlton Heston for the role of "Brett Halliday." However, Dana Andrews was a replacement for Heston, who was deemed by Universal to be too expensive.
