Orson Welles 1938 ‘War Of The Worlds’ Martian Invasion (Video) Orson Welles causes a nationwide panic with his broadcast of “War of the Worlds”—a realistic radio dramatization of a Martian invasion of Earth. [The entire “War of the Worlds broadcast is at the end of this story] Orson Welles was only 23 years old when his Mercury Theater company decided to update H.G. Wells’ 19th- century science fiction novel War of the Worlds for national radio. Despite his age, Welles had been in radio for several years, most notably as the voice of “The Shadow” in the hit mystery program of the same name. “War of the Worlds” was not planned as a radio hoax, and Welles had little idea of the havoc it would cause. The show began on Sunday, October 30, at 8 p.m. A voice announced: “The Columbia Broadcasting System and its affiliated stations present Orson Welles and the Mercury Theater on the air in ‘War of the Worlds’ by H.G. Wells.” Sunday evening in 1938 was prime-time in the golden age of radio, and millions of Americans had their radios turned on. But most of these Americans were listening to ventriloquist Edgar Bergen and his dummy “Charlie McCarthy” on NBC and only turned to CBS at 8:12 p.m. after the comedy sketch ended and a little- known singer went on. By then, the story of the Martian invasion was well underway.
