Star Wars is an American epic space opera multimedia franchise created by George Lucas, which began with the eponymous 1977 film and quickly became a worldwide pop-culture phenomenon. The franchise has been expanded into various films and other media, including television series, video games, novels, comic books, theme park attractions, and themed areas, comprising an all-encompassing fictional universe. In 2020, its total value was estimated at US$70 billion, and it is currently the fifth-highest-grossing media franchise of all time. The original film, retroactively subtitled Episode IV: A New Hope, was followed by the sequels Episode V: The Empire Strikes Back and Episode VI: Return of the Jedi, forming the original Star Wars trilogy. Lucas later returned to the series to direct a prequel trilogy, consisting of Episode I: The Phantom Menace, Episode II: Attack of the Clones, and Episode III: Revenge of the Sith.
