TrekMovie.com has posted excerpts from Star Trek magazine that is out now. In the issue, Star Trek Into Darknese writers Roberto Orci and Alex Kurtzman talk a bit about the movie's big bad John Harrison, the development of the crew and some of the themes they were aiming for while avoiding giving any spoilers.
Harrison as opposite to Starfleet believers:
Well he understands Starfleet because he was enlisted in a similar way. Some might see part of the title coming from the fact that he’s kind of a dark shadow of members of our crew. He too has gone through the process to some degree, that some of our crew have gone though, and clearly for some reason it’s failed to bring him over, so I think he represents that part of our heroes.Enterprise crew still learning:
The relationship [between Kirk and Spock] is still forming itself, and in many ways forms itself over the course of this movie. It also gives us a great opportunity, because of the logic versus emotion conflict is such a brilliant and wonderful backdrop against which to pit a huge problem like Benedict Cumberbatch walking into their life. It isn’t just Kirk and Spock, it’s all of them, and how they’re all functioning together now. They are not the well oiled machine that they were in the original series, because they had gone through many, many more missions in the original series.A theme of hope:
The thing that’s been interesting to us is that, despite the fact that we are literally going Into Darkness, I think we all worked very hard to make sure the theme of hope, what hope costs, and what it’s really about, was always alive in how we were designing our story. So we’re pretty consistent with the last movie in terms of dark things happening, but holding on to the light that Roddenberry set up as a basic tenet of the Star Trek universe.
