 In an interview with The Atlas Society , Ross discussed that her approach to Eve was inspired by Ayn Rand 's objectivism and called Eve 's willingness to " take any sacrifices you might be willing to make " a good example of Rand 's ideology . She compared Eve to Catherine Halsey in Rand 's 1943 novel , The Fountainhead , with Eve most resembling Catherine " at the midpoint of the novel , before she was completely destroyed " . Ross said that her portrayal of Eve was also influenced by Eve White , a character with dissociative identity disorder played by Joanne Woodward in the 1957 film The Three Faces of Eve . According to Ross , she researched books on sociopaths and psychopaths to better understand Eve 's desire to hide her past at any cost .
