Psycho and Style versus Content
It is the nature of the moviechat boards(as it was the nature of the imdb boards before it, and the various other boards that are out there now), that people ...chat. And it seems that most of the chat is usually about the plot of a film.
The exposure of plotholes is a major theme. I pity the poor filmmakers who glossed over their plots thinking their audiences would see the films only one time and never really notice -- boy do they notice in chat rooms. Discussion of characters and their traits(and those of the actors who play the characters) are discussed a lot , too.
Psycho gets a lot of this kind of discussion, as befits the moviechat format. But one can almost hear Hitchcock whispering from the great beyond: "the plot was important, but the style was more important."
And if he whispered that to me, I'd say: "No, in Psycho the plot was more important because that movie had the greatest plot you ever had." A story in which the ostensible lead is killed before the movie is half over, and in which a twist at the end reveals that her killer was someone entirely different than whom we thought done it. A story is which the arena for terror - a shabby isolated rural motel and the Gothic mansion looming on up on the hill behind it-- created a setting that has never been equaled in horror movie history(and I choose the Overlook Hotel in The Shining as second.) A story in which the main victim is killed while taking a shower -- a setting for MURDER that has never been equaled in movie history.
No, Psycho was The Greatest Story Hitchcock Ever Told, and for that reason, I suppose we DO have to linger on the plot.
But still: the style. The movie is suffused with "cinema," start to finish. How we see things is as important as the story being told.
Take that shower murder. On balance, it is a powerful concept. It was pretty scary in Robert Bloch's book, with the terrifying central image of Mother's head "hanging in mid-air' popping through the shower curtain before Mother beheaded Marion(by the way, some folks who read the book have written that ALL Mother does is behead Marion -- one stroke -- but we are later told that no, she slashed away at Marion in the shower BEFORE beheading her as the coup de grace.)
For a 1960 film, Hitchcock had to make changes there. No beheading(and no scene of Norman forcibly stuffing Marion's headless body and that head into a hamper.) And he had to get rid of that terrifying image of Mother's head popping through the shower curtain because...he couldn't show her face. And -- as a matter of style -- Hitchcock replaced Mother's wearing just a head scarf into Mother having a granny's white hair in a bun (shades of Jonathan Winters' Maude Frickert and Johnny Carson's Aunt Blabby, yet to come.)
But even with those changes, Hitchcock had to do other things to make his cinematic shower scene work , while getting past the censors, while taking movie content to a graphic new level. For that's what the shower scene is REALLY about(after being about the plot device of killing the semi-heroine off early.)
The shower scene is about: going on forever. A 1950 "Psycho," if it could have been made at all, with have faded out on Mother opening the shower curtain and holding her knife up high.(And a doubt that a 1950 Psycho would have allowed even that.) A 1960 Psycho would end up allowing -- after battles with the censors on the script and on the finished film -- that murder to proceed ...and to proceed...and to proceed some more. And when Mother left the bathroom...we had to accompany the punctured, dazed-and-no-longer-really-on-earth Marion Crane on her final journey to death -- sliding down the shower wall, reaching out to us, grabbing the shower curtain whose rings can't support the weight of her body and allow for the final fall to death...and yet even THAT is not the end: we get that spectacularly stylized camera move(not a zoom, not a dolly), down the shower drain with Marion's blood and up out of her lifeless eyeball to see the sad, dead corpse Marion has become.
Whew. All that length, all that lingering, all that detail -- THAT is what was historic about the shower scene in Psycho. And once Hitchcock was allowed that breakthrough -- other movies would follow, upping the ante on sex and violence through the 60's until the Hays Code collapsed by 1968 into "anything goes" R-rated freedom. (With a re-release of Psycho getting a rather mild "M" -- today's PG.)
