I seem to recall an interview some time ago, either with Bob Orci, or JJ himself, in which it was confirmed that the black shirt was a tyoe of cadet uniform.
Sorry folks. It looks like its gonna be silly.....
no they didnt..
but if you can actually find out where they say this.. groovy
but so far no has been able to back it up.
(ah i just saw the discussion of the silly ew article_)
by the way... cadets seem to be dressed in red.
and again he dosnt have to be a captain to take over the ship in an emergency....
freaking people watch tos....
grr...
all the time some lieutenant was assuming command.
heck during errand of mercy when spock and kirk were on organiania sulu was in command.
both when enterprise had to flee and later when she came back with other ships.
'
the point of the scene from the trailer is that since they neither captain nor first officer (spock during this time is probably a lt commander) someone had to assume command.
if kirk at this time indeed is a lt then it wouldnt be odd for him to do so.. especially if he was a ranking lt.
or because pike left orders for him.
and considering the significant leaps in time through the movie from post nemesis to 30 something years pre tos, then later different leaps of time as we see kirk at different ages we wont know until the movie comes out just how much time has gone on since kirk entered the academy and the bridge scene where he assumes command.
except i believe some of the characters seem older.
