Film adaptations are movies that are based on existing works, such as novels, plays, or short stories. These adaptations aim to bring the original narrative to life on screen, often reinterpreting the source material to fit the cinematic format. Notable examples include adaptations of J.K. Rowling's Harry Potter series and F. Scott Fitzgerald's The Great Gatsby. The process of adapting a work for film involves various creative decisions, including changes to characters, plotlines, and settings. While some adaptations remain faithful to the original, others take significant liberties, leading to discussions about the balance between artistic interpretation and fidelity to the source material.
