imdb listing
we already knew Sylar from Heroes would be Spock. I'm not sure when they announced it, but John Cho (Harold from Harold n Kumar) will be Sulu, and Simon Pegg will be Scotty.
today they announced Kirk and McCoy. I don't know who Kirk is, but Karl Urban you'll recognize from the Bourne Supremacy and probably other crap.
I guess it's a JJ Abrams film so that's probably a good thing.
I didn't do a search for another thread. I don't care at this moment. I'll be pissed though after someone creates a new thread when it comes out in late in 08.
