BTW, I’m a HUGE fan of Metropolis. We have the blu-ray version of it. One of Fritz Lang’s great early classics. He went on to fame in Hollywood directing “Fury” with Spencer Tracy - horrific story about a lynching. Lang was a master of crowd control.
We’re of a generation that revered foreign film and classic American film unlike the people posting here who admire Kung Fu movies.
FURY is also an amazingly good movie and quite an unsettling one to boot. But "M" is chilling ( sort of an early NOIR, before there was such a category )and Peter Lorre at his best/scariest/most haunted.
Have you ever seen "SCARLET STREET"? TCM is showing it in December and if you haven't seen it, you should.
