Actress Bonnie Bedelia confided to the 8 October 1967 L.A. Times that "they decided I was too old" when she auditioned for the same part as Sondra Locke. As it turns out, Bedelia was four years younger than Locke, who had lied about her age to gain an unfair advantage.
Laurinda Barrett, who played Sondra Locke's mother, was only twelve and a half years older than Locke.
Sondra Locke wed Gordon Anderson a week into filming. One purpose of this sham marriage was to prevent her local reputation as WSM's office trollop from spreading like wildfire as she entered the limelight.
Sondra Locke was the oldest nominee for Most Promising Newcomer at the 1968 Golden Globes. No one knew it at the time, though, because she lied to the world about her age.
