A fascinating look back at the potential ‘Star Trek’ sequel TV show includes some incredible imaginings of what the new USS ‘Enterprise’ may have looked like.

The existence of Star Trek: Phase II—the plans for a Star Trek continuation series in the mid-1970s that eventually gave way to Star Trek: The Motion Picture—has been known for a very long time at this point. We’ve seen concept art, we’ve seen story ideas, and we’ve seen it for long enough to see how those nuggets have gone on to influence the Star Trek that we would go on to get for another 50 years. And yet, there’s still plenty to enjoy in this new documentary about the bumpy road Star Trek almost made on the journey home back to our screens.
