I know he's omnipresent in pop culture right now, and I know he worked with JJ Abrams, but at no point has anyone reported that Cumberbatch is part of the new movies, so I find it really confusing when people angrily insist that he has to be the person narrating the first trailer for "Star Wars: The Force Awakens."
For the record, that is Andy Serkis you hear in the trailer. I was able to verify this, although I was not able to uncover any further information about the role he plays. Here's what I do know, though. He's playing a pivotal role in the film, although he will not have a lot of screen time.
