There's a scene in a Dutch horror movie from the 80's, called The Elevator (De Lift in Dutch) in which an evil elevator kills off people who come too close to the shaft etc.
The plot is extremely poorly written, but there was one scene that was extremely horrifying to watch as it had no CGI and relied only on props and excellent camera angles.
In this one particular scene two guards patrol down a hallway in the building with the elevator. Suddenly both doors open and the elevator seems to be missing. One of the guards inspects the empty shaft and looks down into it. The doors slam shut, trapping his head between them while the evil elevator slowly but surely lowers from above. The other guard watches in horror, falls down powerless on the floor in fear as his colleague gets pushed down towards the floor and decapitated in a very gruesome manner.
Once again, the plot was beyond terrible (especially the ending which explains the entire behaviour of the elevator), but that was one scene I have never forgotten. I was 9 at the time when I watched it.
The scene can be watched here:
