In 1957 Grant Williams and Randy Stuart played husband and wife Scott and Louise Carey in the classic science fiction film The Incredible Shrinking Man (1957).
Pamela Austin appeared on the later Robert Conrad series The Wild, Wild West in the episode The Night of the Whirring Death (1966).
The episode title is explained by Lopaka as referring to someone, usually a woman, who, in a new environment, drops her guard and courts danger.
Although Randy Stuart plays an "older woman," she was only 38 when the episode was filmed. By contrast, her supposedly age-appropriate husband, Whit Bissell, was 53.
