Because they still have to do all the editing and such. Plus, with making the movie premire later it builds up suspence with people and makes them want to go see it more.
That is a good pertanyaan ? But the reason why new moon is'nt coming out early is that it take time for the production peolpe to realse the movie and make sure that everything is done the right way and they are still fiming in itly right now so that is why it not coming out until November ...
I really wish it could come out earlier too, but the film needs editing, reviewing for mistakes, the CGI special effect, etc. So it aint possible to get the movie into theaters sooner...to my great regret
