...on satelite radio! The Original Mercury Theater Production of War of the Worlds Mon 10/30 8:00 pm ET 8 pm ET, October 30, 1938. A nation tuning in to CBS Radio heard a startling broadcast: Earth was being invaded by beings from Mars... Orson Welles' Mercury Theatre radio adaptation of H. G. Wells' The War of the Worlds originally aired as a Halloween special. Welles' genius was to set the story, not in late-19th century England, as in the original, but in 1938 New Jersey, and perform it like a news broadcast. Reportedly, many listeners believed the invasion was real. 8 pm ET, October 30th, 2006. RadioClassics will re-broadcast of the original Mercury Theater production of The War of the Worlds. Listen as a nation did nearly 70 years ago.
