The Star Wars series has spawned multiple live-action and animated films. The series started with a film trilogy set in medias res—beginning in the middle of the story—which was later expanded to a trilogy of trilogies, better known as the "Skywalker saga". The original trilogy was released between 1977 and 1983, the prequel trilogy between 1999 and 2005, and a sequel trilogy between 2015 and 2019. The original eponymous film, later subtitled Episode IV – A New Hope, was followed by the sequels Episode V – The Empire Strikes Back (1980) and Episode VI – Return of the Jedi (1983), forming what is collectively referred to as the original trilogy.
