Before the Nightmares, before Friday the 13th, before Holloween, there was Psycho. Thanks to Hitchcock, the slasher movie lives on. This scene shocked movie audiences in more ways than one. Seeing Janet Leigh taking a shower was atypical by 1960 standards. Killing off the star of the movie was unimaginable by Hollywood standards. In fact, this might actually be one of the most important scenes in movie history. Hitchcock was a genius, but he was also crazy and obsessive about his films. Alfred Hitchcock bought the rights to the novel anonymously from Robert Bloch for only $9,000. He then bought up as many copies of the novel as he could to keep the ending a secret(good thing the internet didn't exist back then).
Forget about the rumors you heard or read on Wikipedia: No, Hitchcock did not arrange for the water to suddenly go ice-cold when the attack started.
The stabbing scene in the shower is reported to have taken seven days to shoot using 70 different camera angles
Hitchcock originally envisioned the shower sequence as completely silent, but Bernard Herrmann went ahead and scored it anyway and after Hitchcock heard it, he immediately changed his mind.
Yes, the blood was Bosco chocolate syrup.
Contrary to popular belief, the knife does penetrate flesh, albiet for only 3 frames.
As you may know, there's going to be a remake of a couple Hitchcock films, mainly The Birds. The film is in pre-production and is being directed by Martin Campbell, the same guy who directed Casino Royale and Vertical Limit. Lets hope it's a little different than the Psycho remake.
