Two enduring misconceptions
It's interesting to see these popular misconceptions appearing even here in reviews by people who have watched the serial. That's how strongly these myths about The Perils of Pauline are apparently ingrained in our culture.
Myth 1. Pauline was tied to railroad tracks. No, she wasn't. That happened to characters in some other films, but not in The Perils of Pauline. (*Certainly not in the surviving 9-part version.) No tying to the tracks, no buzz saw with a conveyor belt, no moustache-twirling Victorian villain. She was bound and gagged a number of times, though.
Myth 2. This serial used cliffhanger endings. Not at all. The danger in each episode was resolved within that chapter. Pauline was never left in a perilous situation at the end. The cliffhanger ending is generally thought to have originated with the slightly earlier Adventures of Kathlyn, but that format was definitely not used in The Perils of Pauline.
