Ever since British actor Benedict Cumberbatch was announced as part of the cast of "Star Trek 2," fans have been arguing back and forth over who the "Sherlock" star might be playing in J.J. Abrams' upcoming sequel. Lots of speculation has centered on whether he'd be playing a familiar villain in "Trek" lore — like Khan Noonien Singh, the most popular theory to date — or an entirely new bad guy.

But perhaps we've all been barking up the wrong tree (or beaming aboard the wrong ship, as it were) as Cumberbatch teased to MTV News on the Golden Globes red carpet Sunday night (January 15) that he might not be playing an antagonist at all.

"I don't think we do know that, actually," Cumberbatch told MTV's Josh Horowitz when asked if his "Star Trek" role is a villainous one. "That's just supposition. And that's all I'm going to say about it."

Perhaps some clues can be found in the fact that Cumberbatch has been preparing for his role by consulting friends and family members better versed in the "Star Trek" universe than he is.

"I started [becoming a 'Star Trek' fan] slowly, but quite genuinely, when he rebooted it with this last film," the actor said of his own "Trek" familiarity. "I have lots of friends and family, all sorts of people who've loved all of the series and all of the films. I've been introduced to it through them and now I'm going back to them and asking them questions so I can get up to speed with true Trekkies."

Though the character's identity remains concealed, whomever Cumberbatch is playing requires no small amount of physical preparation. The actor said he's been "working out nonstop," indicating that his part in "Star Trek 2" is a very physical one. But even if preparation has been somewhat grueling, the actor insists that he's having a blast getting ready for the role.

"[Abrams has] great ideas. It's been great fun to prep," Cumberbatch said. "I start [shooting] next week, which is really exciting, and I can't say any more than that."
