Film sci-fi is often original, with stories that were made specifically for the screen, but there have also been many, many sci-fi adaptations. Many classic novels have been made into sci-fi movies, even previously thought unfilmable ones like Dune, but there are still many great sci-fi novels out there that have never made the leap to the silver screen. These books would make for excellent movies, or in some cases, series of movies.
