Star Wars is an epic space opera franchise initially developed by George Lucas during the 1970s and significantly expanded since that time. The first film in the franchise was simply titled Star Wars, but later had the subtitle A New Hope added to distinguish it from its sequels and prequels. Star Wars was released on May 25, 1977 by 20th Century Fox, and became a worldwide pop culture phenomenon, initially spawning two sequels. Twenty-two years after Star Wars was released, Lucas began the release of a second trilogy as a prequel to the original trilogy. The franchise has also spawned other media including novels, television series, video games, comic books, and other merchandise. These supplements to the film trilogies comprise the Star Wars Expanded Universe, and have resulted in significant development of the series' fictional universe.

As of 2008, the overall box office revenue generated by the six Star Wars films has totalled approximately US$4.3 billion, making it one of the most successful franchises of all time.

Star Wars Episode IV: A New Hope (originally released as Star Wars) is a 1977 space opera film, produced, written, and directed by George Lucas. It was the first of six films released in the Star Wars saga; two subsequent films continue the story set while three others act as prequels. Ground-breaking in its use of special effects, this first Star Wars movie is one of the most successful films of all time and generally considered one of the most influential as well.

Set far in the past, the movie tells the story of a plot against an oppressive Galactic Empire by a group of freedom fighters known as the Rebel Alliance. Seeking to make their authority absolute the Empire has recently completed its ultimate weapon: the Death Star, a moon-sized battle station capable of destroying a planet. Even so, spies have managed to obtain schematic plans of the station in the hope of finding a weakness. Rebel Leader Princess Leia Organa is racing to transport these plans to the rebel base when her ship is attacked and she and the crew are captured by Imperial forces. In a desperate attempt to complete her mission, Leia hides the plans within one of her two servant robots and records a quick message to former military general and rebel sympathizer: Obi-Wan Kenobi. Explaining her circumstances, she begs Kenobi see that the plans are delivered safely to the base. The androids are then launched, in an escape pod, to Obi-Wan's home planet of Tatooine, where they come into the possession of teenaged farmer, Luke Skywalker. The secret message is soon discovered, and Skywalker sets off to locate Kenobi and find a way to help the Princess.

Inspired by films like the Flash Gordon serials and the samurai films of Akira Kurosawa, as well as such critical works as Joseph Campbell's The Hero with a Thousand Faces, Lucas began work on Star Wars in 1974. Produced with a budget of US$11,000,000 and released on May 25, 1977, the film became one of the most successful of all time, earning $460 million in the United States and $337 million overseas, as well as receiving several film awards, including 10 Academy Award nominations. It was re-released several times, sometimes with significant changes; the most notable versions were the 1997 Special Edition and the 2004 DVD, which were modified with CGI effects and recreated scenes.

An expanded radio dramatization of the original Star Wars trilogy was produced in 1981, 1983, and 1996. The first two radio series, based on A New Hope and The Empire Strikes Back, were produced and broadcast by National Public Radio as part of NPR Playhouse. A dramatization of Return of the Jedi was produced by most of the same team and also broadcast on NPR.

The radio serials were made with the full co-operation of George Lucas, who for one dollar each sold the rights to KUSC-FM, the public radio affiliate at his alma mater, the University of Southern California. Lucas also allowed the use of original sound effects and music from the films.

The adaptations for radio are part of the Star Wars canon within its Expanded Universe.

There are no plans to produce radio dramatizations of The Phantom Menace, Attack of the Clones and Revenge of the Sith.

In a galaxy far, far away, a psychopathic emperor and his most trusted servant - a former Jedi Knight known as Darth Vader - are ruling a universe with fear. They have built a horrifying weapon known as the Death Star, a giant battle station capable of annihilating a world in less than a second. When the Death Star's master plans are captured by the fledgling Rebel Alliance, Vader starts a pursuit of the ship carrying them. A young dissident Senator, Leia Organa, is aboard the ship & puts the plans into a maintenance robot named R2-D2. Although she is captured, the Death Star plans cannot be found, as R2 & his companion, a tall robot named C-3PO, have escaped to the desert world of Tatooine below. Through a series of mishaps, the robots end up in the hands of a farm boy named Luke Skywalker, who lives with his Uncle Owen & Aunt Beru. Owen & Beru are viciously murdered by the Empire's stormtroopers who are trying to recover the plans, and Luke & the robots meet with former Jedi Knight Obi-Wan Kenobi to try to return the plans to Leia Organa's home, Alderaan. After contracting a pilot named Han Solo & his Wookiee companion Chewbacca, they escape an Imperial blockade. But when they reach Alderaan's coordinates, they find it destroyed - by the Death Star. They soon find themselves caught in a tractor beam & pulled into the Death Star. Although they rescue Leia Organa from the Death Star after a series of narrow escapes, Kenobi becomes one with the Force after being killed by his former pupil - Darth Vader. They reach the Alliance's base on Yavin's fourth moon, but the Imperials are in hot pursuit with the Death Star, and plan to annihilate the Rebel base. The Rebels must quickly find a way to eliminate the Death Star before it destroys them as it did Alderaan. Written by Derek O'Cain
