When I watched this for the first time in over 30 years, I was surprised how little action there was since I had remembered this as some intense horror movie. Of course, I was young and more impressionable so I guess I just remembered those few dramatic, sensational scenes such as Janet Leigh murdered in the shower and the quick other murder at the top of the stairs. Basically, that was about it, action-wise, BUT I have no complaints because the more I watch this film, the more I like it. It has become my favorite Alfred Hitchcock movie, along with Rear Window. I mention the lack of action, and blood, too, because younger people who might be watching this for the first time are not going to see the kind of horror film they're accustomed to seeing. A generation back, movie makers tended to build up characters and suspense, so there was a lot more storytelling and less action than you see today
No matter how many times one sits through this Hitchcock classic, Anthony Perkins always manages to surprise you. It is a sensational performance - for which he didn't even get an Oscar nomination - I have no way of knowing how much preparation he dedicated to the creation of Norman Bates, maybe no more than usual, but the details of his performance are astonishing. Never a false move and if you follow the film looking into his eyes, you'll be amazed as I was. The madness and the tenderness, the danger and the cravings. A mamma's boy with hellish implications and yet we see, we feel connected to the human being, we are not horrified by him but of his circumstances. In short, we kind of understand him. That alone puts him miles and miles away from other cinematic monsters.
Director Sir Alfred Hitchcock was so pleased with the score written by Bernard Herrmann that he doubled the composer's salary to $34,501. Hitchcock later said, "Thirty-three percent of the effect of Psycho was due to the music."
Director Sir Alfred Hitchcock originally envisioned the shower sequence as completely silent, but Bernard Herrmann went ahead and scored it anyway, and upon hearing it, Hitchcock immediately changed his mind.
