High Quality Content by WIKIPEDIA articles! Serials, more specifically known as Movie serials, Film serials or Chapter plays, are short subjects originally shown in theaters in conjunction with a feature film. They were related to pulp magazine serialized fiction. Also known as "chapter plays", they were extended motion pictures broken into a number of segments called "chapters" or "episodes". Each chapter was screened at the same theater for one week, and ended with a cliffhanger, in which the hero and heroine found themselves in a perilous situation with little apparent chance of escape. Viewers had to return each week to see the cliffhangers resolved and to follow the continuing story. Serials were especially popular with children, and for many youths in the first half of the 20th century a typical Saturday at the movies included a chapter of at least one serial, along with animated cartoons, newsreels, and two feature films.
