Many.
Back before cable, broadcast channels usually showed sports or movies on weekends and after the evening news. Many of those on the list showed up once or twice.
When I got cable in Tulsa in the mid-1980s, one channel showed either Metropolis or Things to Come for weeks at a time.
We always had some late Friday and/or late Sat night local show that would put on B movies of either horror or science fiction. Saw a lot of Vincent Price.
