Now here’s something interesting. In the midst of the trailer’s climactic rush of images, mostly showing people jumping off of high places or falling through space, there’s a brief shot of an unfamiliar character dropping something into a glass of water. After freeze-framing, we can see that the character is played by actor Noel Clarke (Doctor Who‘s Mickey Smith.) It looks like he’s crying. I think that the thing he drops into the water is a ring; I also think that that ring has a Starfleet insignia on it.
So now that we’ve cleared that up…well, I still have no clue what exactly is happening here. But here’s a free-association theory. Noel Clarke looks like he’s being forced to do something against his will. Almost as if he’s being controlled. Almost as if there’s some kind of brain-controlling eel crawling around inside his head. I’m calling it: Noel Clarke is playing a new version of Captain Terrell, the commander of the U.S.S. Reliant in Wrath of Khan. The actor’s last name is Clarke; Terrell’s first name is Clark. Theory: Hypothesized!
