“Oblivion”: a Poster, a Trailer and a Prediction

I like this poster for Oblivion starring Tom Cruise and Morgan Freeman.  The video below is interesting as well. You can probably tell that I’m not ready to jump in line for a ticket though.

POTENTIAL SPOILER ALERT 

My guess, from watching the trailer, is that Cruise is being duped by the aliens/machines.

Earth did not win the war and the survivors rocketed out elsewhere.  I think that there is a small band of survivors and the aliens/machines have brainwashed Cruise in an effort to use him to find the survivors.

Any thoughts?
