I've read about the Cliffhangers! TV serials before, in an article on or off the web about a music composer. Whilst on EpGuides.com just now one TV show name stood out, "Stop Susan Williams". It had episodes 2 to 12, but not the first episode. I then checked out the show on the IMDb and found that it was one of three revolving serials ("The Curse of Dracula" and "The Secret Empire" being the other two). Stop Susan Williams was not completed before the series was cancelled. The complete story of Stop Susan Williams was edited into a TV movie called "The Girl Who Saved the World". The TV movie includes unbroadcast footage used to complete the story. The Curse of Dracula, The Secret Empire and Stop Susan Williams were shown on NBC between February and May 1979. Do Universal own the rights to these three serials?
