From Wikipedia: “On January 14, 2013, Vulture reported that Zack Snyder would be working on a stand-alone Star Wars film; a Jedi/samurai type based on the film Seven Samurai.”
It’s already been done: http://www.youtube.com/watch?v=F13CTKTkMvc
That’s an interesting idea, and certainly bringing Star Wars back to its Kirosawa roots (New Hope was heavily ripped off from Hidden Fortress, so much so that Lucas provided the commentary on the criterion DVD). Not sure how well Snyder’s epic violence works in Star Wars though.
