I was not quite 8-1/2 when this was released, and when it showed up at our neighborhood movie house (the late, lamented Avalon in south St. Louis), my mother -- who had a thing for Joan Crawford -- couldn't get a sitter for me, and insisted I come along because she didn't want to miss it. I didn't want to go, since I had seen the poster outside as I walked by the theater. With all the sophistication that an eight-year-old can have, I thought it would be simply a Bad Movie.
She dragged me to it anyway -- I sat on the aisle and she sat next to me. At the first bloody axe murder, I said "This isn't good for people to watch, I'll be waiting for you outside," and jumped up and walked out.
For the next ten minutes or so, I stood at the box office, chatting with the ticket seller and the ushers, probably all teen-agers, who were bemused by this little movie critic who had left his mother inside. Then Mom came out, smiled sheepishly, and said "David, you were right." We walked home, and she said she wouldn't try to take me to this sort of movie again.
The big irony? Eleven-and-a half years later, I had discovered fandom, and was attending a convention in Kansas City at which the late Robert Bloch (or "RobertBlochauthorofPsycho" as he had come to be known to the general public by then) was a featured guest -- as a joke, I even got him to autograph the blood stains I had somehow unknowingly gotten on my shirt (I think I had accidentally scratched my side against a parked car or some such, as the seam was torn).
I had no idea he'd written this movie until just a short while ago.
I think he'd forgive me, given the circumstances.
