Which movies scared you during your childhood?

[The Great Owl]

We all have movies that scared us when we were children, and these are not necessarily horror movies. Sometimes, movies that are seemingly innocuous can really freak out someone at a young age.

I'll get the ball rolling...

Once Upon a Time in the West
This Sergio Leone movie was showing on TBS Superstation once when I was eight or so. There's a scene early in the movie when Henry Fonda and his henchman shoot a father and his children from the woods behind the father's home. Seeing Henry Fonda kill the youngest son without any remorse whatsoever really got to me at that age. At the time, my family and I lived in a subdivision where our house bordered a forest, and, after seeing that film, I used to have nightmares about gunmen coming out of the woods to kill all of us.

The Earthling (1980)
Ricky Schroder (from the Silver Spoons TV show) plays a kid who watches his parents die in a tragic accident while they are vacationing in Australia. He is left alone in the vast wilderness until he crosses paths with an old man, played by William Holden, who teaches him how to survive. Until...
This was a fun childhood movie in many ways because of the whole wilderness adventure aspect, but the death of the parents at the beginning was terrifying.
(The Earthling has never been released on DVD or Blu-ray. I've got an "unofficial" DVD from a bad VHS transfer, but it does not suffice. This movie needs to be restored to Blu-ray someday.)

Invasion of the Body Snatchers (1978)
I was nine when I saw Invasion of the Body Snatchers on television, and, without revealing too much in detail, the ending of the movie was quite nightmarish for me at a young age. I had seen scary movies before then, but those movies had all had happy endings or, at the very least, tidy resolutions. The outcome of this movie, along with the general paranoid cinematography, really got under my skin.

Assault on Precinct 13 (1976)
If you've seen this John Carpenter film, then you know exactly why this scared me during my childhood. I was 11 when I first saw this movie, and I'll never forget seeing that ice cream truck scene for the first time. The images later in the film of the street gang lining up beneath the trees to shoot the police station got to me as well. The whole idea that a police precinct, which generally represents safety and stability, being totaled by a street gang was quite unsettling for me at that age.

Your turn...
