This theatrical trailer for The Empire Strikes Back features early looks at many sequences from the film. The trailer shows glimpses of Luke Skywalker's duel with Darth Vader on Bespin (in which lighstaber effects had yet to be added, making both Luke and Vader's weapons appear to have white blades), Han Solo shooting at Vader on Cloud City, and the Hoth battle (including AT-ATs and snowspeeders). The format of the trailer then shifts, showcasing each hero individually: Luke Skywalker, Han Solo, Princess Leia, Lando Calrissian, C-3PO, R2-D2, and Chewbacca, and various scenes in which they are featured. The trailer features no narration except for the end, and is driven primarily by John Williams' end credits music as well as the "The Imperial March," a classic Star Wars theme that would make its debut in The Empire Strikes Back. Tellingly, Boba Fett is nowhere to be seen in this trailer, but the official logo for The Empire Strikes Back does make its first on-screen appearance here.
