The Uncanny (1977, trailer)

There's no shortage of monsters to haunt our dreams. Like the creature from the Black Lagoon, deadly aliens from outer space, giant ants, man-eating sharks and bloodthirsty grizzly bears. But the most fiendish, the most fascinating, the most terrifying creature of all, may be waiting for you round the next corner.

Or living right in your own home. Years ago, people used to believe a cat was the devil in disguise. I'm beginning to think they were right. Oh no, no! Cut! I said scream. Do you call that a scream?

Those are spikes, real spikes coming towards you! I just don't feel scared. I would show you what you're going to convince the people what you're writing about is true.

I had access to the police statements and the doctor's report on the voltage. Believe me, I do know what happened. Pins of men.
