Jeez. I already know the whole story from the trailer. I HATE THAT.
Here's what I think happens:
Jack was there 60 years ago. Like the survivors he was placed in suspended animation. It's obvious the Earth goverment who left Earth wanted him. Took his pod and then reawoke him and messed around with his memories. That's why he's reading old books and has a closeness with the past. Because that was his past. I wonder if that woman is his wife or girlfriend. Or some sort of relative.
I won't catch it in the theartres unless it's got good word of mouth. But I might catch it on tv in a couple of years.
I have a feeling its a quasi Matrix-esque movie. Where instead of all the humans being hooked up to machines most of them have been killed. Cruise and his female partner are unaware of all this since being in suspended animation or something similar and led to believe they won the war. They are told they have to serve some type of term fixing the drones and after a few years are allowed to "rejoin" everyone. Truth is they are just killed and replaced with two others. The reasoning for the swapping is to make sure they don't learn the truth.
The truth is that the "humans" lost the war and the bad guys have long since left. They left the drones around to make sure the rest of "humanity" is killed off. They program the drones to ignore two humans per I guess cycle so as to repair them. Morgan Freeman's character is some type of leader to a resistance cell trying his best to get Cruise to help them out (maybe to kill some type of mother ship in Earths orbit?).
Man I watch/read to much sci-fi. If I'm wrong I'm wrong but this does look very interesting.
