Okay, this is gonna be vague, but I'm hoping someone can put these pieces together and help me figure out a movie scene that has been in my head for years!
While at a friend's house in the 80's, we were watching HBO. While waiting for Swamp Thing to come on, there was another flick from what I recall is an android gone bad. However, I can't be sure it was an android and not simply a hyper-strong killer. Anyway, the scene I remember is a person standing in a doorway, when the killer grabs the victim over the mouth (as if to stop them from screaming), and slams the victim into the wall. The victim slides down the wall with a blood streak remaining.
We got a bit freaked out and turned it off prior to the ending, but I was told that the killer (possible android) ends up falling down a well.
Does any of that ring a bell?!
I apologize for the vagueness, but it's all I got and I thought folks here could help!
