A Phoenix "Side Road" : Grisly Murders Imported from Vegas
Alfred Hitchcock in general -- but perhaps particularly in Psycho -- wasn't much for getting into the real detail of a city, its inhabitants, its surroundings. I suppose "Vertigo" is an exception, with its many, many, many location shots around 1957 San Francisco and the rural environs nearby.
And yet, a little of this kind of detail "edges into" Psycho.
Primarily because Hitchcock elected to begin Psycho in Phoenix, Arizona. Phoenix is not a city that was in many movies(any movies?) before Psycho ,and it hasn't been in that many since.
One supposes there was curiosity - - worldwide - about that opening sweep over the Phoenix skyline, with its small skyscrapers framed by rocky desert vistas. One can picture the international audiences for Psycho -- the folks in Japan or France or London -- wondering about the desert city where the film starts.
Why DOES Psycho start in Phoenix?
The book starts in Dallas, Texas. That's where "Mary Crane" works in real estate, and her sister Lila is gone to...Fort Worth (not Tucson) for the weekend.
Mary drives north from Texas, up through Oklahoma, short of Illinois and Robert Bloch's Bates Motel ends up in an "un-named state." Possibly Kansas or Missouri.
Hitchcock wasn't much for mid-American locations at the time. When his movies weren't in urban New York City, they were often set in California : Shadow of a Doubt, Vertigo, The Birds.
Hitchcock seems to have decided that HIS Bates Motel would be in rural, inland, backwater Northern California -- north and east of Vertigo's San Francisco, south of Oregon. Near a city called Redding --about 200 miles north of the inland Northern/Central California capital of Sacramento.
I expect Hitch decided that for "now Marion Crane" to make a long drive into California, she could only start from a few locations: Portland Oregon(driving south to California), Southern California cities like Los Angeles and San Diego (and she "brushes" Los Angeles on her trip to the Bates Motel, purchasing a Los Angeles paper en route).
Or she could start in Phoenix, Arizona...a trip requiring hundreds of miles of driving and not allowing for a "short drive north" starting in Los Angeles.
Hitch got some easy symbolism out of Phoenix -- that's a bird. A mythical bird that, if memory serves, was re-born from death and its own ashes to rise again.
Like Mrs. Bates.
Aside from the opening second unit camera sweep(which certainly establishes Phoenix), and some shots taken at Phoenix intersections to show Marion leaving town(with Xmas decorations on the street screwing up the timeframe), Phoenix exists in Psycho as ...a state of mind.
And that state of mind is largely represented by...oilman Tom Cassidy, he with his Stetson cowboy hat, his bolo tie, his drunken manner, his flirtatious ways drifting into predatory behavior.
Cassidy gets one line that puts a little shock into Psycho early on. "You should spend the weekend in Las Vegas," he tells Marion..."the playground of the world."
The "shock" is how, if for only a moment, Hitchcock's formal, hermetically sealed, and(in this movie) Gothic claustrophobia is briefly punctured by the idea that Marion might "go to Vegas," and hang in a city which, in 1960, was run by Frank, Dino, Sammy, Joey and Peter (aka The Rat Pack), with a swinging US Senator in tow who was looking to be the President.
Cassidy's line famously triggers an exchange that the censors removed from Psycho in 1960:
Cassidy: You should spend the weekend in Las Vegas...playground of the world!
Marion: I intend to spend this weekend in bed.
Cassidy: ...only playground that beats Las Vegas!
Ha. Sexual. Direct. Part of Cassidy's ongoing come-on TO Marion, and a reminder that we just SAW her playing in bed...with the handsome Sam Loomis.
(This exchange was restored for Van Sant's 1998 remake -- where it came off as too broad and old-hat.)
Anyway, for those who wanted to think about it in 1960, Hitchcock by deciding to launch Psycho in Phoenix Arizona was already "tainting" the story of Psycho with the kind of "sinful atmosphere" that would power the entire horror movie to come. For Phoenix in 1960 was a real estate boom town of sorts, evidently already ridden with East Coast gangsters come west who were using Vegas for main operations....and Phoenix as a nearby support city.
You might say that Marion Crane -- ironically, as with everything else in Psycho -- left the "criminal hotbed" of Phoenix Arizona for the "backwoods rural contentment" of Fairvale California -- but (of course) actually headed straight for human behavior at its most foul and insane and dangerous.
