Re: Why didn't Chekov ever make Captain?
^ One (possibly apocryhal) story that I heard was that Walter Koenig encouraged the extras playing the journalists to refer to him as 'Captain Chekov' in their adlibbed chatter during the scene where the TOS trio first walk into the Ent-B bridge, but it got picked up by somebody when they were watching the dailies and it was wiped out in the sound looping session afterwards.
It wasn't wiped out. Not only can you hear it, but you can see
one of the journalists as he says it.
