for those of you who want to be spoiled on the plot, Wikipedia now has the full plot writeup about it. I spoiled myself, but movie sounds really good.
After watching the movie, I was browsing Wikipedia, and noticed that there also spoilers listed on at least one of the individual actor's Wikipedia pages. So anyone not wanting to be spoiled (though why are you reading this thread now if you don't want to be spoiled?) should avoid the actors' Wikipedia pages.
