I’d like to see a Star Wars heist film in the vein of Heat.
Also, as has been mentioned in here, an Indiana Jones movie (maybe starring a young Lor San Tekka) about a space archaeologist (who is not and never will be Force-sensitive) who digs up Jedi/Sith secrets.
A Boba Fett film where they kill off clone Boba sometime during the run of the Clone Wars TV series (which he shows up in as kinda a wannabe bounty hunter) just because I want what George did to the character to be retconned so badly. Barring that a redo of the Twin Engines of Destruction story would be cool. Someone mentioned something similar earlier in the thread.
