I didn't tell you what you should call it. I simply said it's idiotic to do so when the film was only titled that for three or four years.
I guess you think Lucas and Lucasfilm are idiots because they weren't promoting it as A New Hope back in 1997 when they released the Special Editions to the theaters. Check out the Special Edition Trailer and around 1:30 they advertise them as Star Wars, Empire Strikes Back and Return of the Jedi. Not once is the name A New Hope mentioned, and that is 20 years after the movie was released!
Only when Lucas made the Prequels, did he start advertising them with Roman Numerals and then started calling it A New Hope. No one is arguing that they were in the opening crawl, but even Lucas still called it Star Wars for the first 20 years!
So I guess George Lucas is as idiot as we are! LOL!
