Old Halloween Movies?

Hi Dreadit!

I’m already getting excited for Halloween season and am starting to put my horror movie list together for October. I’m wondering if there are classic horror movies (pre-1970) that have the holiday of Halloween as a plot point (or that at least take place during Halloween). I know there are plenty of great pre-1970s horror movies; I’m just not finding any that involve Halloween.

Can’t wait to read your suggestion!
