This 1-hour historical documentary from the PBS Network takes a close-up look at the significance of the date October 30, 1938 (@ 8:15 pm) when the "Orson Welles" dramatization of "The War of the Worlds" was aired on the radio (coast to coast) all across the USA.
Through stills, archival footage, reenactments, and interviews - The producers of this documentary try to come to rational terms as to why this particular broadcast generated such widespread panic among the citizens of their country.
Looking back, today, at this incident from 80+ years ago - It certainly strikes one as being completely laughable that thousands of Americans actually believed that their country was, in fact, really being invaded by Martians.
