The Split Personality
There is a Hitchcock quote I heard years ago about how everybody has two sides... what matters is how far apart those two sides are.... I wish I had the exact quote (if anyone knows it?).
Many Hitchcock films have dualism as a central theme. Simply defined, dualism = the division of something conceptually into two opposed or contrasted aspects, or the state of being so divided.
The ultimate division would be splitting the mind in two; with two opposite personalities.
I've been reading about multiple personality disorder, now called Dissociative identity disorder (DID). It mostly happens from trauma and/or severe sexual abuse. Watching The Three Faces of Eve, I couldn't help but think of Psycho. The first "real" multiple personality movie: The Three Faces of Eve (1957) was based on a real story of Christine "Chris" Costner Sizemore who developed multiple personalities as a result of her witnessing two deaths and a horrifying accident within three months as a small child. In the movie, Eve (Joanne Woodward) had a coffin with her dead grandmother fall on her, she was trapped with the corpse for a while. The real story was much more traumatic.
[Dr. Jekyll and Mr. Hyde doesn't really count as a multiple personality disorder film because it's a formula/potion causing the change, but it's in the same vein.]
So... What do you think happened to Norman to cause him to split into Mother and when do you think it occurred? I know, I know, I listened to the Psychiatrist explain it...
At the end when the Psychiatrist says "He was only half there to begin with" and "For years they lived as if there wasn't anyone else in the world. But, then, she met a man.." then he explains the split occurred when Norman killed his mother and her lover "because matricide is one of the most unbearable crimes of all" so Norman erased the crime in his mind and became mother. So he split personalities not only to replace his mother but also to block out the trauma when he murdered her.
But, I'm not sure that's the full picture. There's an undercurrent of sexual dysfunction. "A son is a poor substitute for a lover" I always get surprised at that line of dialog. Do you think he was abused in some ways? There's an unsaid feeling about Oedipal type relationship, jealousy, and possessiveness. Norman's main personality has a variety of problems, even without knowing about the Mother split personality. Maybe I'm wrong, but I think it goes deeper than a clingy and overbearing mother. ... the alter personality of Mother emerges when Norman is sexually aroused. This is significant.
QUOTE from wiki: DID: A mental disorder characterized by at least two distinct and relatively enduring personality states. There is often trouble remembering certain events, beyond what would be explained by ordinary forgetfulness. These states alternately show in a person's behavior. Presentations, however, are variable. The primary identity, which often has the patient's given name, tends to be "passive, dependent, guilty and depressed" with other personalities being more active, aggressive or hostile, and often containing a current time line that lacks childhood memory. Identities may be unaware of each other and compartmentalize knowledge and memories, resulting in chaotic personal lives.
The cause is believed to be due to childhood trauma. In most cases there is a history of abuse in childhood, while other cases are linked to experiences of war... The cause of DID is unknown and widely debated, with debate occurring between supporters of different hypotheses: that DID is a reaction to trauma; that DID is produced by inappropriate psychotherapeutic techniques that cause a patient to enact the role of a patient with DID; and newer hypotheses involving memory processing that allows for the possibility that trauma-induced dissociation can occur after childhood in DID, as it does in PTSD. The majority of patients with DID report childhood sexual or physical abuse. end of wiki quote
Nowadays, almost every other movie has the DID/multiple personality storyline. I just watched M. Night's Split (2016) and Scorsese's Shutter Island (2010) these ideas aren't even shocking anymore, it's in everything! These other movies just don't have the effect of Psycho, in my opinion. Thoughts anyone?
