Can you name these movies that were adapted from books? These are films that were not made from short stories, graphic novels, folktales, or comics. So, for instance, Road to Perdition and Stand By Me would not be included because one is based on a graphic novel and the other a short story. Sources: IMDB, Goodreads.
Movies made from plays not included unless there was a book at some point.
For brevity's sake, sequels are not included, only the first film in the franchise.
