Been away for awhile. (Look, I'm still rocking a sombrero!) But now that we have something to actually talk about...
A few things that I noticed. First, the synopsis from the Itunes Movie Trailer site:
"When the crew of the Enterprise is called back home, they find an unstoppable force of terror from within their own organization has detonated the fleet and everything it stands for, leaving our world in a state of crisis. With a personal score to settle, Captain Kirk leads a manhunt to a war-zone world to capture a one man weapon of mass destruction. As our heroes are propelled into an epic chess game of life and death, love will be challenged, friendships will be torn apart, and sacrifices must be made for the only family Kirk has left: his crew." (Emphasis mine.)
So we have a threat from within Starfleet (Sec.31 perhaps)...We have Peter Weller in the cast (remember him from ENT?)...We have a weird looking planet covered with vines...then what could be a planet self destructing in volcanic glory (Genesis, anyone? Which would make Eve's character Carol Marcus in my mind.) We have a "one man weapon of mass destruction" (aka genetically engineered superman Khan).
My theory so far (and it is total conjecture, but then again so is everything else): Khan is in this movie, but he is not the primary villain. The Big Bad is somebody else (Weller perhaps, going back to his xenophobic organization from ENT?). And Kirk and crew go to retrieve an imprisoned Khan who the Klingons somehow got their hands on in the Abramsverse, because they think Khan can somehow stop whatever the Weller character is up to. The "family" is the crew of the Enterprise, and by extension Starfleet itself. Which someone (not Khan) is trying to destroy from within.
This would certainly turn some things on their heads. Which I like. What's the point of the alternate universe if you don't play around with things? Having Khan as some sort of antihero with whom the crew forge an uneasy alliance, instead of a straight-up mustachio twisting baddie would be interesting to me. And it would bring together a lot of different prime universe threads in a totally new way.
If anyone has heard any details about Weller's character that could dump a big bucket of cold water on my theory, let me know. I haven't been following the rumor mill. The plot synopsis on Itunes got me thinking, that's all.
