"Flying Disc Man From Mars" was a 12 episode weekly serial that started on October 25, 1950! Serials were quite popular in the day, and would show along with a cartoon or two before the main feature came on! They were generally about 20 minutes each, and would always end on a cliffhanger to entice the viewer to return the following week, just to see what happened!
There is a survivor, and as Dr. Bryant is about to find out, his name is Mota, and he comes from the planet Mars! No, he didn't bring any marsijuana with him!
Sounds like the name for a cool Hendrix biopic, "Death Rides A Stratocaster!!"
