The filming of the shower scene in "Psycho" required numerous set changes in order to film each camera angle. Davis, along with Marli Renfro, acted as a stand-in for Janet Leigh so that the on-set lighting levels could be checked before Leigh was called on to the set.
In 1988, Davis was murdered and subsequent media reports inaccurately reported her role in "Psycho", which led some to speculate that Davis was in fact Renfro. Author Robert Graysmith, who had a lifelong fascination with Renfro, investigated and subsequently wrote a book, "The Girl in Alfred Hitchcock's Shower" about Renfro's role in "Psycho" and the confusion over Davis's death.
