Shortly after the release of that image, JJ Abrams spoke to Screen Rant, confirming Cumberbatch’s role as John Harrison and offering some insight into the character.
“His name is John Harrison and he is sort of an average,” the director says.
“That is what makes him so scary – he is just an average guy who works in an organization called Starfleet, and he turns against the group because he has got this back-story and this kind of amazing secret agenda.
“After two very violent attacks, one in London and one in the US, our characters have to go after this guy and apprehend him. And it is a far more complicated and difficult thing than they ever anticipated. Into Darkness is very much about how intense it gets and really what they are up against.”
