13 Ghosts (1960 version)
Greetings! I have been a fan of yours since MST3K was on SciFi. Last time I made a suggestion it was for Miami Connection. Imagine my delight when you riffed it later that year!😁
Anyway, I think 13 Ghosts would be perfect for riffing. Of course I don't mean the remake with Tony Shaloub--which I didn't even realize WAS a remake! I caught it on Turner Classic Movies once during Halloween. It is just cheesy enough to be riffable, but not so awful that you can't bear to watch it. I loved it, and was actually interested in how it was going to end. The only thing it has in common with the remake is that there are 13 ghosts and the cast has to wear special glasses to see the aforementioned specters. I have found a trailer that I hope will show just how awesome it would be. Enjoy!
