On 30 October 1938 - that's 69 years ago - Orson Welles dramatised the Martian invasion of Earth during an episode of his popular radio show. Many listeners believed the invasion was real, triggering a mass panic.
Adapting freely from H.G. Wells' science fiction novel War of the Worlds, Welles and his Mercury Theatre On the Air actors recast the story as a realistic sounding news broadcast.
