Back in the mid-1980's, I saw the film Enemy Mine starring Dennis Quaid and Lou Gossett, Jr. When I discovered the move was based on a story originally published in Asimov's Science Fiction Magazine , I decided to track it down. The problem was it's a short story--unless the story was printed in an anthology, they are difficult to find.
Archive.org has the anthology, Reel Futures , which contains not just "Enemy Mine" but 14 other short stories/novellas and one novel ( This Island Earth ) that have been made into movies, usually more than once. And what a trove!
The stories are listed in chronological order, from H.G. Wells and "The Empire of the Ants," to "Air Raid" by John Varley. Most of the stories are quite different from the movie version: the ending of "Farewell to the Master" is much different from either movie version of The Day the Earth Stood Still. "The Sentinel" was greatly expanded to become 2001: A Space Odyssey ; "Air Raid" serves as the opening scene of Millenium .
There is a short biography of the writers and where the story first appeared in the Introduction. Stills from the movie and information about the director, principle actors, and the name of the movie appear before each story.
For those who enjoy older, non-Star Wars, non-Star Trek science fiction movies (the newest is 1989) and like to compare them with their source story, this is a great resource.
NB: Reading the biography for "Eight O'Clock in the Morning," I realized I have met the author, Ray Faraday Nelson--his wife and I are in the same poetry group!
