Star Wars Episode V: The Empire Strikes Back (originally released as The Empire Strikes Back) is a 1980 space opera film directed by Irvin Kershner. The screenplay, based on a story by George Lucas, was written by Lawrence Kasdan and Leigh Brackett. It was the second film released in the Star Wars saga, being followed by Star Wars Episode VI: Return of the Jedi, and the fifth in terms of internal chronology.

The film is set three years after the destruction of the Death Star. Luke Skywalker, Han Solo, Princess Leia Organa, and the rest of the Rebel Alliance are being pursued by Darth Vader and the elite forces of the Galactic Empire. While Han and Leia are chased across the galaxy by the Empire, Luke studies the Force under Jedi Master Yoda. Vader is secretly plotting a trap for Luke that will lead to a vicious confrontation and a shocking revelation.

Following a difficult production, The Empire Strikes Back was released on May 21, 1980, and received mixed reviews from critics, though it has since grown in esteem to become one of the most well-regarded chapters of the saga. It earned more than US$538 million worldwide over the original run and several re-releases, making it the highest grossing film of 1980. When adjusted for inflation, it is the 12th highest grossing film of all time in the United States.
