Through the marvels of DVD technology, I now own a disk on which three of the original (1930's) Flash Gordon serials are compended. There are 13 or 15 episodes per each, having been shown weekly in movie theatres here in the Colonies to keep people coming back (and paying a whole DIME to get in). At the beginning of each "all new" episode, there is a recap of the most exciting scenes from the last "all new" episode, to bring the viewer up to the cliff-hanger, so it makes sense.
