In 1938, Orson Welles scared the crap out of millions of people by reading 'War of the Worlds' on the radio as if it were an actual newscast, causing wide spread panic.

Tomorrow, the H.G. Wells book will be read again on air -- to promote the Zac Efron movie 'Me and Orson Welles.'

The broadcast begins at 8PM on Oct. 30 -- which is exactly 71 years and one minute after the first time the legendary actor pulled the stunt that led Americans to believe aliens were invading.
