According to trekmovie.com, the working title for the next Star Trek film has been confirmed as Star Trek Into Darkness.
The site stated:
Paramount tested a number of titles for the film over the summer, including at least one title that did not include “Star Trek.” Also noted in our earlier article, the title (by design) does not include a colon, like were used for the Next Generation films such as “Star Trek: First Contact” or “Star Trek: Nemesis.”
While Paramount will not officially confirm the news, multiple sources have told TrekMovie this is the title they are going with as of now. It has also been reported by ComingSoon that Paramount has secured the domain names to both www.startrekintodarkness.com and www.startrekintodarknessmovie.com, neither of which has any content.
Since there hasn’t been an official announcement, we can’t call it the ‘final title’, but all signs are pointing that way.
