Although "The Chosen One" is a title which is decidedly on-topic for the events that take place in the film, it's not only redundant (Episode One: The Chosen One), but it also seems very dull to me. Doesn't sound like a classic title, nor is it a title which would compel me to watch the movie. It's mysterious, but not very exciting.
To find a title, first we have to analyze the other titles it will be in the company of. ALL of the titles refer to the broader-scale galactic events we see unfold in the film. Shroud of the Dark Side, Revenge of the Sith, A New Hope, The Empire Strikes Back, Return of the Jedi. Really read these titles and compare them with any ideas you have. We would like to avoid "of the", I do know that was something we decided earlier. So, if any of you have any BRILLIANT, well-thought-out ideas, please let us know.
Personally, I like "Star Wars: The Battle Begins". I'm not saying "it's the one!" But that one just appeals to my personal taste. I must admit, although the novelty of being title-less is intriguing to me, I'm also a little bothered by it for the reasons previously pointed out by darthpreston.
I want to make it clear, however, that by commenting on this, I'm not necessarily fostering the idea that now "we need a title", but at this early stage, I feel it shouldn't be a matter that has been completely taken off the table.
In the end, I'd be just as satisfied with having no title, and would rather have no title than one that doesn't fit 100%.
