Hey there and thank you for reading!
This has been driving me mad for thirty years. I caught a brief moment in a movie when I was very young, and all I can remember about it is that there was a madman who was murdering people in various ridiculously complicated ways (sort of like The Abominable Doctor Phibes) and one way was to force a person through a small tunnel or a hole or something. I think the contraption was set up like a model train table and a conveyor took the person along a track where they were compressed or pushed through this hole.
This would have been on network TV some time in the early 1970s. Could have been a TV show, or a movie shown on TV. I’m sorry I can’t be more specific. I caught just enough of it to flip out, at which point my parents sent me back to bed. Does this ring any bells? Even remotely? Thanks in advance for your help.
