The call came through the studio with a single, breathless warning: stop the broadcast. But Orson Welles and his Mercury Theatre players had already started. At eight o’clock on Halloween night, 1938, their radio drama began as if it were just another episode. Then the interruptions began, and the world stopped being ordinary.

A news bulletin cut through the music, claiming strange explosions had been detected on Mars. Another report followed, then a live interview from a farm in Grover’s Mill, New Jersey, where something had apparently crashed. The panic in the announcer’s voice felt terrifyingly real. Witnesses described a monstrous machine rising from a cylinder, firing heat rays that incinerated onlookers.
The National Guard was overwhelmed. Seven thousand soldiers were dead. And then, as if that were not enough, the invaders released clouds of toxic gas and marched on New York. The entire production was a work of fiction, adapted from H.
G. Wells’ novel. The scripted “news reports” were performed by actors. Howard Koch, the playwright, had chosen Grover’s Mill simply by pointing at a map hanging in a gas station while driving to his parents’ house.
Yet the use of sophisticated sound effects and genuinely chilling performances made the whole thing feel impossibly real. Before the show even began, a voice had made the nature of the program clear: “The Columbia Broadcasting System presents Orson Welles and the Mercury Theatre on the air in War of the Worlds by H. G. Wells.
” CBS had also insisted on a second announcement during the program itself. But many people tuned in late, catching only the bulletins and not the disclaimers. Before the hour was over, police began to fill the studio. One actor later recalled the room slowly filling with officers who wanted to stop the broadcast.
They pushed against the producers and CBS executives, some of whom were holding them back so the performance could finish. Only after the show ended did the phones start ringing off the hook, so many calls coming in that the CBS news chief described the scene as bedlam. In the chaos, Welles retreated. The future director of Citizen Kane looked beaten, telling the head of CBS News, “I’m through.
” He seemed certain his career was finished. For decades, the story of what happened that night has repeated the same way: thousands of people panicked. New Yorkers flooded the streets, convinced they were watching an alien invasion in real time. In Grover’s Mill, residents were said to have tried shooting at their own water tower because they believed Martians had taken it over.
Some versions of the story even claimed people died from shock. But none of that ever really happened. Modern researchers have taken a closer look at the evidence, and almost none of it holds up. A survey of five thousand households found that fewer than two percent were even listening to Welles’ broadcast that night.
Many more people were tuned into a hugely popular comedy variety show on another station. The few listeners who did catch “The War of the Worlds” largely recognized it as a Halloween trick. So why did the panic become the accepted truth? Because the newspapers wanted it to be.
The radio was cutting deeply into their profits. Advertising money that had once gone into print was now flowing toward the new medium, all while the country was still struggling through the Great Depression. The newspapers had every reason to make radio look dangerous and irresponsible. When some listeners complained about Welles’ broadcast, newspaper owners seized on the opportunity.
They sensationalized the response, wrote dramatic headlines, and gave the public the story of a nation in hysterics. Their goal was simple: convince advertisers their money was safer in print. Even the government was not convinced. The Federal Communications Commission did investigate the broadcast.
After reviewing the circumstances, they concluded that no laws had been broken. They went one step further, barring complaints about the program from being used in license renewal hearings. It was their way of saying the whole panic was a fabrication. Welles himself had no plans to cause trouble.
He later explained that the broadcast was meant to be an experiment. We wanted people to understand they shouldn’t take any opinion pre-digested, that they shouldn’t swallow everything that came through the tap, whether it was radio or not. But as he admitted, “It was only a partial experiment. We had no idea the extent of the thing.
”
The news coverage about the supposed hysteria did its damage, but Welles’ career emerged unharmed, perhaps even boosted by the publicity. He went on to become one of Hollywood’s greatest directors. The broadcast also was not even the first radio hoax. Twelve years earlier, in January 1926, the BBC had its airwaves hijacked during a live discussion of 18th century literature.
The interruption lasted twelve minutes, claiming riots were raging across London. Big Ben had been blown up, a politician lynched, and a famous hotel burned to the ground. The most bizarre detail: the script was written by a Catholic priest. If life imitates art, it turns out it sometimes imitates the urban legends about art, too.
In 1949, a Spanish-language version of Welles’ script was performed on the radio in Ecuador. Listeners panicked for real. The fear escalated into riots and chaos in the streets. At least seven people were killed, including close relatives of the producers.
Both the radio station and a newspaper that had fueled the panic were burned to the ground. It was a tragic warning of what could happen if people believed everything they heard.
