^ I do remember an early spoiler that we would actually see both timelines during the film - and cut back and forth between them. For whatever the hell *that's* worth.
Interesting. Thanks for the info.
In any case, if Nero is somehow determined to kill Kirk, bringing alternate Kirk to either replace "real" Kirk or alternate Pike could be bait for Nero to go after Enterprise instead of Vulcan or w/e.
Maybe the story that JJ Abrams "always wanted to tell" was: What if an everyday person could "become Captain Kirk"?
. Of course this was already the theme of "Galaxy Quest".
