Here's another idea I have for a possible film.

In the centuries between the Great Hyperspace War and the Sith War, a Jedi lieutenant known as Lord Cawdor serves the king of a backwater world recently admitted into the Republic, tasked with hunting down remnants of the Sith believed to be hiding on the planet. After he and his apprentice track down a trio of darkside sorceresses, Fawdor receives a prophecy that the current king will soon die and he, Fawdor, will rise to take his place. Hearing this news, Fawdor begins to hunger for the throne of his king, and under the manipulative influence of his ambitious wife, he eventually arranges for the death of his master. Once upon the throne, however, Fawdor finds himself a victim of both his own conscience and the slain king's vengeful son.

(Yes, this is basically just a cross between MacBeth and Hamlet placed in a Star Wars setting).
