Is the screenplay supposed to be different fromt he Movie

I just go through reading the screenplay and realized that it goes againts lots of spoilers we already have. Did they purposely leave out certain things that are still under raps or is the screenplay more of a "final" version of the film?

the screenplay is official, spoilers are not right always

i hope they leave stuff out....otherwise all the good stuff will be revealed.

At least the screenplay doesnt ruin the movie for you though...the book will make you feel like things are left out (has been my experience with book before the movie) always more in the novels than in the movies...So all the screenplay will make you do is want to see it that much more!
