Case study of "PSYCO"

"PSYCO" is an American thriller made in 1960 by British director Alfred Hitchcock.
The film is based on a book also called "PSYCO" which was written by author Robin Bloch. it was also turned into a screen play in the early 60s.

"PSYCO" stars Janet Leigh and Anthony Perkins as the two main characters Marion Crane and Norman Bates.
The music was written by Bernard Hermann and Hitchcock was pleased with the end result as he said that "33% of the effect of Psycho was due to the music"

On the first viewing of "PSYCO" in had received a mix match of both good and bad reviews for example Bosley Crowther a well known and highly ranked film critic for The New York Times wrote "There is not an abundance of subtlety or the lately familiar Hitchcock bent toward significant and colorful scenery in this obviously low-budget job."

But in contrast the New York Herald Tribune reviewed the thriller film as  "..rather difficult to be amused at the forms insanity may take... keeps your attention like a snake-charmer."
The biggest proof of the films success was the seal of approval from the public and the box-office as there were mass crowds forming at cinemas full of people wanting to watch this astounding film. As far as box-office is concerned it reportedly obliterated records in Asia, France, Britain, USA, Canada and South America.
