I'm surprised the highly-secretive J.J. Abrams is saying anything about Star Trek Into Darkness, but he spoke with MTV to discuss a few details regarding the Klingons and the role of Carol Marcus (Alice Eve).  The Klingons were previously seen in Star Trek deleted scenes to show that Nero (Eric Bana) was their prisoner for a matter of years before managing to escape and go back to waiting for Spock to come through the wormhole.  Abrams sneakily revealed the fan-favorite race back in June, and he tells MTV, "Their role in this is definitely that of adversary, and you'll see how that plays out."

Hit the jump to find out how Carol Marcus figures into the story.  The film also stars Chris Pine, Zachary Quinto, Simon Pegg, Karl Urban, Zoe Saldana, Anton Yelchin, John Cho, Bruce Greenwood, and Benedict CumberbatchStar Trek Into Darkness opens in IMAX 3D on May 15th, and in 2D and 3D on May 17th.

Abrams tells MTV that fans shouldn't expect the film to slow down to create a romantic development between Kirk and Marcus:

"(Kirk) meets her fairly early on and again she plays a science officer, she's someone who is a part of the adventure.  I think Chris is right, because it's very much an action adventure movie and once that gets going it's a very difficult thing to park the story. So it's very difficult to do a romantic interlude. Her role is important, she wouldn't be in the movie otherwise."

For those who need a refresher on their Trek lore, in the original timeline, Kirk was in a relationship with Marcus, but the two went their separate ways.  Kirk later discovered that he had fathered a child, David, with Marcus.  Mother and son were working on the Genesis Device, which Khan attempted to turn into weapon in The Wrath of Khan.

Here's the interview with Abrams:
