Like the background monitor image. Not like J.J. Abrams.
When Abrams appeared in an MTV Movie Awards sketch last weekend, it seems he got into a little of his Lost-ian "look for the clues, superfans!" shenanigans, sneaking the above background Klingon image into a shot of him in the editing room with his Star Trek sequel. As TrekMovie points out, Abrams has already established that his Klingons wear masks like the one seen here--the alien race was cut from the first Star Trek but turned up in a deleted scene you can see here--so there isn't really a question of whether or not it's a Klingon. The question is: is it an intentionally-placed clue about the new film, or is it just, like, a Klingon screensaver that happened to be caught in this moment between a loving shot of Worf and Alexander and a photo of a lady-Klingon's cleavage.
Well, according to HitFix, it's the prior. They contacted Paramount, where reps were cagey about giving anything away but did confirm, yes, it's a still from the new film, it's a Klingon, and "the image wasn't included in the clip by accident."
In short: the upcoming Star Trek sequel will have at least one Klingon, but NOT MY KLINGON.
