Film adaptations of novels were among the first films ever made, and continue to impact the film and literature industries. As technologies advance, video games have joined the adaptation scene as well. Adaptation theory is a field of study that analyzes adaptations and attempts to understand how they are created and how they interact with their sources and other texts. I began with a review of previous research on adaptation theory, and then I used The Witcher franchise, a fantasy series that follows monster-slayer Geralt of Rivia, as a case study for my own research. I compared different versions of The Witcher (two short story collections, the first season of the TV show, and the third RPG game), and read articles and reviews about The Witcher and other adaptations. Using this background, I determined three questions that are helpful to analyze adaptation: What is being adapted? What is the goal of adaptation? What is the role of fidelity in adaptation? Finally, I used these three questions as guidelines to write my own short story and create outlines for a short film and a video game adaptation of the story.
