Back in February, we brought you the first behind the scenes images from the set of director J.J. Abrams‘ as yet Untitled Star Trek Sequel. Some of the photos featured Spock (Zachary Quinto) facing off against the unidentified villain of the film, portrayed by Benedict Cumberbatch, who was seen wearing what appeared to be a black version of the Starfleet uniform under his silver overcoat in one of the shots.

Now, we might actually know who that villain is. If you don’t want to know, you might want to turn back now, the rest of this article is definitely spoilery!

The good folks over at TrekMovie are reporting that after beating out a number of Latino actors, including the likes of Benecio del Toro with what is being called a “powerful audition”, Benedict Cumberbatch is actually portraying Khan Noonien Singh in the follow-up to 2009’s Star Trek.

Additionally, they report that Leonard Nimoy, despite his “retirement” will be returning as Spock Prime , and Klingons will also be featured in the film.

The as yet Untitled Star Trek Sequel starring Chris Pine, Zachary Quinto, Zoë Saldana, Karl Urban, John Cho, Anton Yelchin, Bruce Greenwood, Simon Pegg, Benedict Cumberbatch, Alice Eve, Peter Weller, Nazneen Contractor and Noel Clarke is slated to hit theaters on May 17th, 2013.
