1981 Dark Night of the Scarecrow

Misguided townsfolk, blinded by bias and fear, mistakenly kill a mentally retarded man after someone accuses him of raping the young girl he had befriended. Shortly thereafter the entire town is beset by a supernatural terror. The story originally aired on television.

I remember watching this movie from when I was a kid and it scared the crap out of me! There is just something very scary about scarecrows. This is perfect to watch on a creepy Halloween night with the lights out.
