I wanted to see this film serial because my grandfather acted in it. His name was James Spencer. I found this serial to be a great example of the genre of that time. While I found some of the plot points alittle "dated", I can see why these projects caught the imagination of our best directors of today, ie. Spielburg & Lucas. BTW.. If you see the first episode, one of the scientists crew who land on the lost island is the great cowboy star and once married to Dina Shore, George Montgomery.
