Anime compilation films have existed for decades as a unique movie format. They consist of movies that compile or condense content from a TV anime series into a feature-length film, sometimes with added scenes, re-edited content, or improved animation, depending on the circumstances, but typically cutting out filler and 'unnecessary' content to get an anime's story out in less time. These films have played a pivotal role in shaping the anime landscape, offering fans a new way to experience already beloved stories while introducing casual viewers to expansive franchises in a more digestible format before anime hit the mainstream.
