The Star Wars franchise involves multiple live-action and animated films. The series started with a trilogy set in medias res that was later expanded into a trilogy of trilogies, known as the "Skywalker Saga". The original 1977 self-titled film (later subtitled A New Hope) was followed by the sequels The Empire Strikes Back (1980) and Return of the Jedi (1983); these films form the original trilogy. https://en.wikipedia.org/wiki/List_of_Star_Wars_films
