Eltab
Lord of the Hidden Layer
Setting a movie during the Prequel Trilogy, the story interacting with the (deliberate but secret) sabotage of the Republic's institutions. The heroes overcome the threat du jour even though The Authorities did little / nothing to help. All-new characters, never goes close to Tattooine or Trantor err excuse me the capital planet/city. Maybe cameo Tarkin in a low level of responsibility, chafing at orders that prevent decisive action ... and ignores them to follow his own judgement. (This is when the bad guys start chasing the heroes for serious.)
