Revenge of the Sith

[Nan]

Can't copyright an existing word, so, no.

Particularly since it's Revenge of the Sith, not Return.

Trivia: The Return of the King was originally titled The War of the Ring. Tolkien thought The Return of the King as a title gave away too much of the story.

Not as much as, say, Frodo Finally Gives In To The Dark Side, but meh.

Trivia #2: Sith is also an existing word. It's an archaic form of "since."
