What I thought would be kinda neat for the various expanded universe and origin stories is if they would take a classic film or story and use it as a loose template for a Star Wars movie. I mean, imagine a Star Wars movie showing how Han meets Chewy while a bounty hunter chases them that’s loosely based on The Good, The Bad, and The Ugly! Or maybe a movie where Obiwan guards a young Luke on Tatooine based on Lone Wolf and Cub?
I think that’s really the formula for the original trilogy, which were based on big aspects of some westerns, ww2 movies and classic Asian movies like The Hidden Fortress from Kurosawa.
