Stories with existing characters:
• Obi-Wan western. This seems like a no-brainer since everyone and their mom just goes right to the concept. I see it as a combo of SHANE and FISTFULL of DOLLARS. Star with Ben being down and dissolution, weak connection to the force... maybe a little drunk. After collapsing in the desert he's found by some moisture farmers, and they nurse him back to health. He gets his act together, and when he realizes the farmers are being harassed for land taxes by Jabba and his goons, slowly but surely Ben gets his mojo back to help the farmers fight off the goons.
• Darth Vader horror film-- a small rebel tech crew fixing a comm relay on the far side of Yaavin are stuck in the jungle when the Death Star explodes. The see a tie fighter crash and hope it has a radio they can use. The wreckage is a mess-- so they have to hike back to Yaavin bas. Along the way, some mysterious monster in the dark begins to pick them off... it's Vader. So basically Friday the 13 with Vader subbing for Jason Vorhees.
• Boba Fett movie-- I know he's over-rated. I know I'm a total fanboy for wanting this-- I have no shame. Pretty much the only thing from the EU I like is Fett surviving the pit. Here's the problem: Star Wars is about good versus evil. Having a "bad guy" as the lead wouldn't work. Also, no offense to Temura Morrison, but you couldn't hang a movie on him. He's good-- but he's not that good. So Fett for whatever reason, gets a new face, and a new actor to play him. When he comes out of that pit, he's changed his tune. He wants to make up for all the bad he's done, and he's going to give the Alliance/New Republic some serious dirt on the criminal underworld-- so every other bounty hunter of note comes out of the woodwork to stop him.
Original ideas:
• The FIRST Jedi-- I know the comics did it.. but MEH.
• I always liked the concept of the CSA in the Han Solo books. It actually works well with the prequels. It was cloudy, but before the Clone Wars the Republic had no military outside of Senatorial guard and the Jedi. Individual planets/systems had their own military. All commerce was handled by corporations, guilds, and conglomerates. (Mining Guild, Techno Union, Trade Federation, etc). Again, you have to read between the lines of Lucas' poor writing to see his great idea-- Palpatine attracted all the commerce guilds into the Seperatist movement, and gave them a unified army. This forced the Republic to use the Clones they discovered, and behind the screen, you can assume all that commerce had to be federalized, and corporations that stayed loyal (like Sienar Systems) were given the market share. Obviously this makes for a smooth transition to a fascist Empire. In the original Han Solo books, the Corporate Sector was home to all the megacorps that supported the Imperial war machine. They were located in some far off pocket of the galaxy where they could operate without oversight. So basically-- like Monsanto having a super sketchy research lab on a boat in international waters. I think there's a great story that could be set here that captures the spirit of Star Wars. Say some planet held by a corporation makes use of its inhabitants as slave labor in their factories. The story is about a small group of saboteurs trying to escape and get their freedom-- and along the way, realize they can take down the big bad guy. In their way, the CSA, Corporate Sector Authority-- the private army that protects the corporations.
• Hamlet adapted to Star wars... it's a perfect story for it.
