Imagine it’s late 1983. Return of the Jedi had just been released, and as we filtered out of the cinemas and fleapits of the day, uncertain of there will ever be any more Star Wars, we recieve news of a new trailer for episode 7. And then episode 8. Returning to the cinema’s for a second viewing of Jedi, we see this.
Many of you weren’t around back then (check the comments on this video for proof of that) but use your imagination to see what the teaser trailer for The Last Jedi would have looked like.
