Revenge Of The Jedi - 1982 UK Teaser Trailer
https://www.youtube.com/watch?v=MAW1E3JIQZE - from the official Oscars YouTube channel (35 sec long)

The blurb:
“The Academy Film Archive holds several trailers from the United States with the initial ‘Revenge’ title, most of which announcing a May 25th 1983 release date which coincided with the anniversary of the original Star Wars stateside release in 1977. However, this peculiar and very brief Revenge of the Jedi teaser trailer originated from a cinema in the United Kingdom, where the film was originally being considered for a Christmas 1983 release. This rare teaser, preserved by the Academy Film Archive, was apparently shown with the U.K.’s May 1982 double feature re-release of Star Wars and The Empire Strikes Back. American audiences would not get a glimpse of the third film until Star Wars was re-released in the U.S. in August 1982, meaning that this may be the earliest Revenge trailer distributed – and fans from across the pond got the first peek!”
