TrekMovie.com has it on good authority that Star Trek Beyond is being used for the title of the new Trek film. What we do know is that the name has been registered with the Motion Picture Association of America (MPAA), a step that typically signifies a title has been settled on for an upcoming movie. It is possible, given Bad Robot’s history of secrecy and pretense, that this is merely a decoy name registered to stir up conjecture amongst the media and fans. But, the official title will need to be registered with the MPAA before the film’s release, and given the timeline, it seems likely that such a decision would be made now.
