A number of Corman’s movies were shown on MST3K.
The Saga of the Viking Women and Their Voyage to the Waters of the Great Sea Serpent (I am a Grimolt Warrior!), Gunslinger, Attack of the Giant Leaches. MST3K Classics.
There was also X-the man with the X-ray eyes, which was a good movie actually. Death Race 2000 too.
