Star Wars expansion
If I were to make a movie set in the Star Wars universe, I'd base it off a soap Box racing event.
Synopsis:
Three friends decide to enter a land cruiser competition. The rebel and Empire take a back seat but you see the occasional storm trooper or you hear about rebels. The kids work on learning how to build the racer, raise money for the parts, put up with an intial loss (mechanical failure) , witness the superiority of the best team, get into a fight among eachother, have a setback due to a successful rebel espionage causing an embargo on trade and an inflation of prices, the reforming of the group, and the race where they need to work together to possibly eek out a win.
I really dislike star wars, but this story would speak better to most audience members. It would expand the lore and it could be taken out of star wars and added to any other environment. The themes of teamwork, ingenuity, discovery, overcoming obstacles, and putting it on the line works.
