The Three Faces of Eve, 1957

Ralph White to Eve White: I've never seen you take a drink before.
Eve Black to Ralph: Honey, there are a lot of things you've never seen me do before. That's no sign I don't do 'em.

I have been watching "My Own Worst Enemy". In the show Christian Slater plays "Henry" who works for some kind of terrorist organization, perhaps the government. Not clear.

The part of the show that interests me is Slater's split personality. In his brain a chip has been implanted giving him two distinct personalities: "Henry", an assassin spy type and "Edward"; an ordinary guy complete with his own memories, life and reality. When working properly the brain chip switches his awareness to one or the other personality.

An intriguing idea. Story telling aside, is it truly possible to have more than one personality?

"The Three Faces of Eve" is supposed to be based on a true story about a woman suffering from "split personality". Joanne Woodward plays Eve White, Eve Black and Jane. Her transitions between the three personalities are similar to Henry and Edward's. There is a dizzy spell followed by an extremely brief black out and then "poof" they are switched.

The title to this as well as Joanne's portrayal suggests to me that Eve was one personality. The different Eves and Jane are well but separately developed "facets" of that one personality.

This interpretation does not upset my apple cart. There can't really be two personalities in our heads, can there?
