Book adaptation is the process of transforming a written work, such as a novel or short story, into another medium, typically film or television. This involves interpreting the original narrative, characters, and themes to create a new version that resonates with audiences in a different format. Adaptations can vary in fidelity to the source material, with some closely following the original plot while others take creative liberties. Successful adaptations often capture the essence of the original work, appealing to both fans of the book and new viewers. Examples include adaptations of J.K. Rowling's Harry Potter series and F. Scott Fitzgerald's The Great Gatsby.
