So, what have we learned?
First off we can confirm that was indeed a futuristic London in the teaser poster, as the film kicks off with none other than Noel Clarke in the capital, playing a devastated father whose daughter is gravely ill. But he's in luck - that nice Benedict Cumberbatch is on hand to offer his assistance!
"I can save your daughter," he promises Clarke, and before you can say "I have a bad feeling about this," we're whisked away to the Enterprise and dropped straight into the middle of a no-holds-barred action sequence.
Those couple of minutes with the Brits aside, this opener is a much shinier and more colourful affair than the distinctly gloomy teaser trailer, and finds the Enterprise crew struggling to save the population of an alien planet from extinction by volcanic eruption. This is the mysterious red planet glimpsed in the trailer; Kirk and Bones are on the ground, fleeing from the aliens who don't seem to have taken too kindly to their presence, while Spock's about to be lowered into the volcano itself armed with the device to defuse it.
It's all handled with the same quippy irreverence and lightness of touch that defined Abrams's first reboot. Just about every character gets their catchphrase in, from Bones's "Damnit, man!" to Scotty's "I cannae guarantee it, cap'n", but there's an undertone of moral questioning that feels closer to old-school Trek, as Kirk arrives back onboard just in time to be told that Spock must be left to die.
Of course, there's no real stakes to this moment since we're pretty sure that Spock isn't going anywhere at this point in proceedings. What the scene does do is set up what's bound to be an important payoff down the line, as Kirk asks Bones what Spock would do if the roles were reversed.
"He'd let you die," Bones replies grimly, and we're left to wonder how long it'll take for this theory to be put to the test.
And that's not to mention the most significant line of all. Amid Kirk's protests, Spock explains that he must be left behind because "the needs of the many outweigh the needs of the few".
First an iconic moment was recreated in the extended trailer; now an iconic line of dialogue from Wrath of Khan has shown up too. If Star Trek Into Darkness isn't a direct Khan remake, it's certainly not shying away from its legacy.
One last note on that front: the footage is followed by an extended version of the teaser trailer. The extended voiceover we heard in the Japanese trailer - with Cumberbatch asking "Is there anything that you wouldn't do for your family?" is intact, but the much-discussed shot of Kirk and Spock's hands touching through glass is not. Curiouser and curiouser...
The first nine minutes of Star Trek Into Darkness will screen before The Hobbit: An Unexpected Journey at selected IMAX 3D screens from today (December 14).
