I included the trailer for the film on this post about the author of the story Adjustment Bureau is based on, Philip K. Dick. Now that it's been released, I hunted down some more information about the movie and found a featurette that gives a little more details about the movie. Check it out:
The one key thing that got me about this particular featurette was the exchange between Matt Damon's character (who is campaigning to be a NY senator) and the Adjustment Bureau Agent:
"Why won't you let me be with Elise?"
"Because she's enough. If you have her, you won't have to fill that void inside of you with applause & votes."
I find that interesting because it adds entire volumes of meaning to the actions of the AB. Think about it. If Damon's character doesn't become a senator because he falls in love, then he won't be in a position of power to stop a damaging piece of legislation that ends up killing millions of people, or to help a state law come into existence that is a key that leads to something great, or he just won't fulfull his potential. And in another point in the featurette, the AB make it clear that the same will happen to her. All her dreams and aspirations (of becoming a dancer from what is shown) will not come to pass presumably because she'll be fulfilled with him as well. They will lose their drive to succeed because of their love for each other.
It's kind of like the thinking behind Chaos Theory. One small action can lead to hugely varied events, and that action is the result of ONE SINGLE CHOICE. It's EXCEPTIONALLY thought provoking! I can't wait to see this movie and how they play this out.
