There were two sequences shown at Cinemacon. The first was an extended version of the IMAX preview shown with The Hobbit. The additional bits showed Kirk decide to take the ship out of the ocean in order to save Spock by transporting him out of the Volcano. The sequence ends showing the Nibiru natives looking up at the Enterprise and beginning to pray to it.
The second scene takes place apparently much later in the movie. It starts with Kirk walking into the Enterprise sickbay to confront Harrison (Cumberbatch) to reveal everything he knows about "that ship." Harrison clearly knows a lot rattling off details such as "Dreadnaught Class. Two times the size – three times the speed – advanced weaponry – minimal crew…built solely for combat." Kirk then convinces Harrison to help him, after some banter Kirk promises "you said you would do anything for your crew, I can guarantee their safety." Harrison is dubious but Kirk returns "are you coming with me or not?"
Specifically Kirk wants Harrison to come with him to another Starship – this ‘Dreadnaught class’ ship is the ship that has been discussed in analysis on TrekMovie.com. And apparently this other Federation ship has damaged Enterprise severely. Kirk and Harrison then prepare to go over to the ship but first Kirk calls Scotty who is already on the other ship (why he is there is not explained). Harrison starts barking instructions to Scotty and Pegg’s lightens things up by incredulously saying things like "are you crazy? whoever you are" to Harrison. Scotty isn’t too happy about the idea of opening an airlock to let Kirk and Harrison in after they space jump over, but he sets about to make it happen.
Kirk and Harrison then get into space suits prepare to launch out of the Enterprise and have to navigate a debris field. At the same time Scotty is trying to get things ready on the other ship. There are also shots of Spock, McCoy and Sulu on the bridge. There is a classic exchange between Spock and McCoy where Spock says he doesn’t have "the information or confidence" to confirm if the plan will work, and McCoy quips "you’re a real comfort."
Kirk and Harrison then get launched into the debris field where they have to dodge around towards the other ship where Scotty is frantically trying to prepare to open an airlock without getting sucked into space (he isn’t wearing a spacesuit). Eventually Kirk’s faceplate gets cracked, adding to the tension. And to make things worse Scotty gets confronted by a very large security guy (not in standard Starfleet uniform) who doesn’t seem to buy Scotty’s story that he is just there to "do a wee bit of maintenance on the airlock console."
As Kirk and Harrison get closer Scotty continues to deal with the big guy aiming a phaser at him. Scotty asks him if he is Starfleet or "private security." The reason becomes clear soon enough because Scotty opens the hatch and launches the guy out the airlock while he has strapped himself in–essentially killing the big guy with the gun. Soon after Kirk and Harrison fly through the opening and afer closing the airlock Scotty quips "welcome aboard." And that was the end of the sequence.
Just hours after two bomb blasts provided a deadly conclusion to the Boston Marathon, principals from "Star Trek Into Darkness" were doing their jobs: putting on happy faces and plugging their big-budget film on the opening night of the annual movie-theater convention, CinemaCon.
"We were all on the way out here just talking (about how) it is hard to go and pimp your movie on a day like this, when the nation is sort of coming together," said one of the movie's writer-producers, Damon Lindelof.
"My cousin ran the Boston Marathon today. He finished half an hour before the explosions went off," he said. "So, I'm just relieved that he's OK. And I'm praying, and my thoughts are with the families of people that were injured or hurt in any way by this horrible thing."
Lindelof's longtime collaborator, "Star Trek" series writer-producer-director J.J. Abrams, stayed back in Los Angeles to work on the sound mix of the film.
But a number of film's actors made it to Sin City for the convention: Chris Pine (who plays Captain Kirk), Zachary Quinto (Spock), series newcomer Alice Eve (Dr. Carol Marcus) and John Cho (Sulu).
Like Lindelof, Cho had mixed feelings about hyping a movie on the same day as a national tragedy.
"This is part of the job for us," Cho explained. "(But) it was a weird feeling. I'm just going to say that. It's so sobering."
Perhaps one reason is that, like the Boston bombings, "Star Trek Into Darkness" is propelled by a terrorist. The story pits Kirk against John Harrison (portrayed by "Sherlock" actor Benedict Cumberbatch), a one-time top Starfleet agent, who threatens the survival of both Earth and Kirk's Enterprise crew. "Terrorism is a huge part of our lives," noted Pine, "and we all know the effects of that."
For Quinto, the Boston bombings struck even closer to home. He recently completed a theatrical production of "The Glass Menagerie" there.
"I mean, I just lived in Boston the last three months," Quinto said. "I was horrified. It's just unfathomable. It's an amazing city and I know it's stronger than one tragedy like this. But it is certainly enough to set everybody back in an unfortunate and profound way."
