The War of the Worlds
The War of the Worlds is a novel by H.G. Wells that was first published in 1898. The novel deals with a possible invasion of Earth by fictional Martians, who in the story are technologically more advanced than the humans.
Radio broadcast and panic
A 1938 radio dramatization of the book by Orson Welles caused a panic when many listeners mistook the story for an actual news broadcast, causing panic in many parts of the United States.
The book has been reworked many times. There have been modernizations, sequels by other authors, alternate tellings (including one where Superman fights the Martians), several films, and even a musical.
