The dedicated fan following of J.J. Abrams knows that the talented writer/director is great at keeping secrets — particularly when those secrets revolve around the highly anticipated and heavily guarded "Star Trek" sequel. And while a few details have started to emerge about the 2013 release, including cast additions (like Alice Eve) and villain speculation, we don't know much.

When MTV News caught up with Simon Pegg and producer Bryan Burk when they were promoting "Mission: Impossible - Ghost Protocol," we asked what they know so far and if they'd seen or heard any official talk about Khan, the rumored fan-favorite villain.

Pegg swore he doesn't know anything about new characters that have joined the story, but he does know that his Scotty will have a particularly creative sex scene.

"There is a large group sex scene with Scotty and some green chicks. That's all I know; that's all I've been told. It was a sweetener," he joked. "That was my condition for doing the film."

While Pegg assured us that what he had read of the script is, in fact, really "good," he knows nothing about Khan.

"I haven't heard the name Khan come up. Not to say it won't come up, but I have heard no mention of him whatsoever," he said. "He is a great villain. I don't want to say too much and then have to eat my words as I often do, but we've seen Khan [in a 'Trek' movie before]. To see him again, how much value is there in that? I don't know."

Burk was equally coy about the superhuman tyrant's place in "Trek 2."

"There are amazing villains all throughout the 'Star Trek' universe as well as new villains," he said when asked for his thoughts on whether Khan belongs in the new film. "As we did in the last film, there's a lot of directions you can go with the film. In this case, we chose to do something we thought would be original and unique and different, and I think on paper, we made the right choice. Now we have to go shoot."

Burk also promised that the second film will pick up where things left off.

"Unlike the last film, where we were restarting and setting up the characters ... we're going to jump right back in, and we don't have to set up everybody and we can go right in it," he explained. "We're kind of in a mad dash at the beginning of the film. In all of our conversation, we reference a lot of our favorite films and how 'Empire Strikes Back' was spectacular and how they were able to pick up and keep going."

Abrams' "Star Trek" sequel starts shooting in 3-D in January and is scheduled to be released May 17, 2013.
