Alien Invasion is self-explanatory and the target is usually, but not always, our Earth. It is a common theme in science fiction stories and film, in which extraterrestrials invade Earth either to exterminate and supplant human life. The classic of this subgenre is H.G. Well's War of the Worlds, which has been presented in radio by Orson Welles' in 1938, the 1951 feature film classic, and Stephen Spielberg's film version. |
