ANSWERED: Not the Original Title
According to IMDb rules,
We use the original title of a movie/show in its original language as it appears on screen in the opening credits.

Which means this title:
http://www.imdb.com/title/tt0076759/?ref_=fn_tt_tt_1
Should be just plain "Star Wars" not "Star Wars - Episode IV A New Hope."
For proof, I offer the original movie opener (before Lucas started messing with it)....
