I've seen all of them multiple times. I own 4 of them on DVD of blu-ray:
DRACULA (1931)
The MALTESE FALCON
GONE WITH THE WIND
CASABLANCA
The first time I saw Caligari was on a local PBS station back in the 1970s. I loved it!
Me too! I saw DR.MABUSE, THE GAMBLER on the same station-34 WSJV PBS out of Grand Rapids, around the same time too. And NOSFERATU. It was the only place you could see silent movies! Beyond a Harold Llyod show that was on Sunday morning on channel 22.
The PBS channel in my area (WGBH, Channel 2) also showed Nosferatu. In addition, they showed concert movies that were simulcast on a local FM radio station so you could listen in stereo! I remember watching Gimme Shelter and a few others. They showed Monty Python episodes, too, which I thought was cool because it was one of the few ways you could hear mild swearing like "bastard" on TV and see an occasional buttock or animated boobs.
