The blurb:
“Watch The Empire Strikes Back theatrical trailer, which debuted in fall 1979 and gave audiences their first look at the sequel to Star Wars. In addition to a sampling of scenes taken from the entire movie, the trailer surprisingly features footage that was cut from the final film, including a kiss between Luke and Leia, C-3PO removing a warning sticker from a door in the Rebel base on Hoth, and more. Most interesting, however, is the voiceover – provided by none other than Harrison Ford himself.”
