The Empire Strikes Back, also known as Star Wars: Episode V – The Empire Strikes Back, is a 1980 American epic space opera film directed by Irvin Kershner and written by Leigh Brackett and Lawrence Kasdan, based on a story by George Lucas. The second installment in the original "Star Wars" trilogy, as the sequel to "Star Wars" (1977), it is the second film in the franchise to be produced, and the fifth episode of the "Skywalker saga". The story is set three years after the events of the first film, as the Galactic Empire hunts the scattered Rebel Alliance throughout the galaxy. While Darth Vader relentlessly pursues Luke Skywalker's friends—Han Solo, Princess Leia, and Chewbacca—Luke studies the Force under Jedi Master Yoda to prepare himself for his upcoming confrontation with Vader.
