Hmmm... a couple of things I noticed in the movie (among the many things that caught my eye):
* A metallic red-coloured, three-nacelled Starfleet starship - at the spacedock (looking not unlike an Armstrong class starship)
* At the end of the movie, when we get a shot of the Enterprise, instead of x2 impulse engines on the primary saucer, it appears that the middle section (with impulse vents on either side) is also glowing red - giving the appearance of one long bar of impulse engine arrays. I thought I also heard it mentioned that the Enterprise had been refitted / repaired - and I presume that the modified impulse engine vents was part of this refit...
In both instances, I might have been mistaken - can anyone else confirm either of these observations?
Hope I wasn't seeing things... :P
