http://www.imdb.com - Note that Im referring only to the film not the book. Im not out to ruin anyones fun so Im avoiding spoilers as far as possible. Im not here to write a critical review of Enders Game.And my point is not to fact check the movie but to place it in the context of the things we actually know about biology evolution and the physics of other worlds. Science goggles engaged.Aliens in the movies are always coming to Earth because they covet our water they do it again in Enders Game. This theme dates back at least to the late 19th century quasi scientific studies of Percival Lowell whose 1895 book Mars depicted the planet as a dry dying world populated by aliens who had constructed enormous canals in an attempt to save their civilization.
