As Abrams told MTV News, “Their role in this is definitely adversarial and you’ll see how that plays out.” What exactly that entails could be anyone’s guess at this point. So what took so long for them to finally appear? Abrams talks about that in the interview as well, “We had shot some stuff [in the first film] that had Klingons and we cut the scene. It’s a deleted scene on the DVD. But they’re back in this one.”
But superfans also know that isn't exactly fresh news. Last summer, the always secretive Abrams snuck in a very quick, blink-and-you'll-miss-it look at the Klingons from 'Darkness" during a sketch in the MTV Movie Awards (see above). It was included intentionally as a tease for fans, and while Klingon talk died down since then, it looks like there will be a lot more for Captain Kirk to tangle with than just John Harrison.
Hopefully, knowledge that the Klingons will be returning will make fans even more pumped for the upcoming sequel than they were before. With “Star Trek” being as successful as it was, “Star Trek Into Darkness” is surely the most widely anticipated Trek film to date. We’ll see whether it’ll live up to everyone’s expectations when it comes out on May 17th.
