This is that Star Wars teaser trailer VERY loosely recreated using only scenes from the original trilogy. Just like the title said. So if you came here expecting to see the trailer for one of the ORIGINAL movies made with footage from FUTURE Star Wars movies, you came to the wrong place. The door you were looking for is down the hall marked 'PSYCH WARD'.
Keep going for the trailer plus the real one for comparative porpoises (I think I like them even more than dolphins!).
Thanks to J. Oliver H, who has his fingers crossed for some alien nudity in the new movie.
