Steven, I also remember being terrified seeing "The Birds!" LOL! My dad LOVED horror movies. When we lived in Atlanta (1973) there was a local station which showed horror movies all night long. It was called "Friday Night Frights."
We'd put blankets and pillows down on the floor and get down there with Dad and watch the scary movies. I probably made it till about 9:00 before falling asleep, but I bet he watched them all.
Anyway, there was a very old movie, and I don't know the name. (Steven, if you get this one, then you DO KNOW EVERY HORROR MOVIE EVER MADE!) Anyway, there were these creatures--I think they were supposed to be aliens, but I'm not sure. They had needles that came out of their fingertips, and it would show a closeup of the fingers with some kind of clear fluid dripping off those needles! They would kill people by sticking them with the needles. When I think of being scared by a movie, that's the one that always comes to mind. I think that maybe it was because I was so afraid of needles, being a sickly child.
Also, there was one that I think was called "The Giant Spider." It lived in a cave, and...well...it was about a giant spider! It was super old, too. These movies must've been made in the 50s.
