Damned creepy movie and if I had seen that as a kid, would have disturbed me for sure. My parents thought I was disturbed enough without that.
I drove them nuts when the original "Invasion of the Body Snatchers" came out with constantly checking under my bed for a pod. Even setting an alarm to get up and check. I figured they might prefer the pod me as that was more controllable. Same thing with "Invaders From Mars" when I was 6. I thought they would have offered me up to have one of those little mind control devises installed in my neck but that was silly, I gave up on that after a year of checking my neck periodically during the night and for sure every morning.
