"Based on a short story" refers to a creative work, such as a film, television show, or play, that takes inspiration from a previously published short story. This adaptation often involves reinterpreting the original narrative, characters, and themes to fit a different medium or audience. These adaptations can vary in fidelity to the source material, with some closely following the original plot while others may take significant creative liberties. Notable examples include adaptations of works by authors like Edgar Allan Poe or Ray Bradbury, where the essence of the short story is transformed into a new artistic expression.
