Star Wars (also known as Star Wars: Episode IV – A New Hope) is a 1977 American epic space opera film written and directed by George Lucas, produced by Lucasfilm Ltd. and released by Twentieth Century-Fox. It is the first film in the Star Wars franchise and the fourth chronological chapter of the "Skywalker Saga". Set in a fictional galaxy under the rule of the tyrannical Galactic Empire, the film follows a resistance movement, called the Rebel Alliance, that aims to destroy the Empire's ultimate weapon, the Death Star. When the rebel leader Princess Leia is captured by the Galactic Empire, Luke Skywalker acquires stolen architectural plans for the Death Star and sets out to rescue her while learning the ways of a metaphysical power known as "the Force" from the Jedi Master Obi-Wan Kenobi. The cast includes Mark Hamill, Harrison Ford, Carrie Fisher, Peter Cushing, Alec Guinness, Anthony Daniels, Kenny Baker, Peter Mayhew, David Prowse, and James Earl Jones.
Lucas had the idea for a science fiction film in the vein of Flash Gordon around the time he completed his first film, THX 1138 (1971), and he began working on a treatment after the release of American Graffiti (1973). After numerous rewrites, principal photography began in March of 1976 in locations including Tunisia and Elstree Studios in Hertfordshire, England. Lucas formed the visual effects company Industrial Light & Magic to help create the film's visual effects. Star Wars suffered production difficulties: the cast and crew believed the film would be a failure, and it went $3 million over budget due to delays.
