Psycho 11 and III say, in effect, there's no way to survive with a psychological problem. If you've got it, the law can keep you locked up because there's no chance for cure.
In Psycho IV, the time is five years after III, and Norman is out of the hospital. He's a married man, and he's finally learned how to love somebody and have natural sex without killing his lover.
It's not like the original movie where you thought it was the mother committing the murders, but it was actually the son. I don't think it's possible to create the kind of shock today that we created in 1959. And I don't even want to try.
We were mainly concerned about nudity - how much could be shown in 1959 and how much would convey, without being gratuitous, the terror of being attacked naked and wet.
I didn't know it at the time, but Hitch didn't want to talk to me - he hated meeting with people he might have to reject. As it turned out, someone, maybe his agent, insisted that he interview me.
