GabiMoro: The most scary movie that I saw was one with a giant killer octopus/squid, but I don't recall its name. I couldn't sleep the whole night.
I saw it before 1994, so probably the movie it's from the '80s.
The movie has a scene in which a man runs into a car graveyard and manage to go away with a car, but then the tentacles from above the car kill him.
There is also a scene where little kids pick up eastern eggs hidden in a garden, and a tentacle is visible in the sewerage but nobody is harmed.
A man is grabed by tentacles underneath a garrage door and later parts of his body are discovered.
The action takes part in a inland town (no sea or river as I remember).
If somebody could tell me the name of the movie I'll be very happy. Sorry for derailing the thread.
I would really like to help you with this, unfortunately I'm not too savvy on creature/natural horror... plus, your "octopus/squid" could just be an alien with tentacles, or any kind of lovecraftian thing. I browsed for it, but couldn't find anything that matched your description, I'm guessing it would be better if someone who actually watched the movie told you its name.
No need to apologize for derailing the thread, since you didn't derail anything; this was meant as place for us to share horror b-movies with each other, so if anyone knows the name of that movie, we all win, that's another new suggestion.
