Much secrecy has surrounded the development and production of director J.J. Abramsâ sequel Star Trek Into Darkness, but fans were hoping at least a little more by way of plot details or the identity of the villain would be revealed once the marketing campaign kicked in. Thus far weâve seen a poster and a teaser trailer with quite a bit of actual footage, but in true Abrams fashion it appears that the unveiling of this material has only raised more questions and speculation.Now one Trek fan has painstakingly delved into a scene from the Japanese trailer that is incredibly similar to a scene in Wrath of Khan, possibly revealing the identities of the characters whose hands are seen touching through glass. Hit the jump for more.With the marketing campaign for Into Darkness getting off to a running start, weâre starting to see more than a few nods to the classic Wrath of Khan film. Steve attended a press day for the film (click here to read his recap and watch a video blog) where Abrams revealed that Alice Eve will be playing Carol Marcus, a character from Khan, and the name of the villain played by Benedict Cumberbatch was recently revealed to be John Harrison. This name is likely a red herring, and fans are becoming more and more convinced that Cumberbatch will indeed be playing that dastardly Khan.The Japanese trailer for Into Darkness featured an image that was reminiscent of a scene from Wrath of Khan in which Kirk and Spock touch hands on opposite sides of a glass panel before Spock dies. One of the hands in the Into Darkness trailer is obviously Zachary Quintoâs given the "live long and prosper" formation, but fans seem split on whether the other hand is Chris Pineâs or Cumberbatchâs. One such Trek fan has done some research into the hands of the aforementioned actors.Over at the Deviant Art page, thereâs quite a bit on pinky curvature, hand size, and even fingernail shape, but the most damning evidence comes by way of the shape of the actorsâ pinkies and the vein in their hands (click to enlarge):As such, it does indeed appear to be Pineâs hand against the glass opposite Quintoâs.  So what does this all mean? Well it could mean that Kirk will be sacrificing himself to save the ship instead of Spock, or that Kirk is poised to die some other way, or that J.J. Abrams just enjoys driving Star Trek fans crazy. Whatever the case, all will be answered when Into Darkness opens in theaters on May 17, 2013.click on the image below to see the full breakdown
