You’d think they would have a database of all SW titles just so this doesn’t happen?
At the very least, I would think someone at Lucasfilm would at least check to make sure there isn’t some obscure thing out there already called The Phantom Menace, or Attack Of The Clones, the owners of which who could sue them later?
Ehh…it doesn’t really matter all that much. A title is just a title. The best thing to do is to create the title that you think best suits the entirety and meaning of your feature film.
