The Empire Strikes Back, Return of the Jedi, Revenge of the Sith, The Phantom Menance, and *snicker* Attack of the Clones. These are the subtitles of the Star Wars saga.
We'll disregard A New Hope because Star Wars was just called Star Wars when it first came out. Fuck you, George Lucas.
With casting resolved for J.J. Abrams' entry in the series, rumours are circulating about what the new movie will be called. Well, word has it Star Wars Episode VII is subtitled The Ancient Fear, or at least that's the working title.
For the record, Star Wars was actually called Blue Harvest during filming, so take all this with a grain of salt.
If the new Star Wars is called The Ancient Fear, that's fine. The reference is apparently directed toward Max von Sydow's character, who is obviously really bad. We'll know more well before the movie opens next Christmas.
