Star Wars is a 1977 American epic space opera film written and directed by George Lucas, produced by Lucasfilm and distributed by Twentieth Century-Fox. It was the first film released in the Star Wars film series and the fourth chronological chapter of the "Skywalker Saga". Set "a long time ago" in a fictional galaxy ruled by the tyrannical Galactic Empire, the story follows a group of freedom fighters known as the Rebel Alliance, who aim to destroy the Empire's newest weapon, the Death Star. When the Rebel leader Princess Leia is abducted by the Empire, Luke Skywalker acquires stolen architectural plans of 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.

Epic films have large scale, sweeping scope, and spectacle. The term is slightly ambiguous, sometimes designating a film genre and at other times simply big-budget films. Like epics in the classical literary sense, it is often focused on a heroic character. An epic's ambitious nature helps to set it apart from other genres such as the period piece or adventure film.
