A few that stick in my mind: The Wasp Woman, Screaming Skull, and House on Haunted Hill. Wasp Woman, especially, mesmerized me as I studied it while waiting for my dad to pay our property taxes--in those days, the downtown "opera house" showed movies and always of the horror variety. I also recall "Blood of the Vampire." These were all approximately 1957/58 or so, I believe. I was all of 5!
