Things that I noticed that couldn't have happened....
For example, Troy is locked up in a room with hundreds of old cell phones. He picks one up and dials his girlfriend in Detroit, which is a world away and deep from a bunker underground. This was suppose to take place in 1991. Also this was not a Sat phone(which wouldn't have worked anyways).
I don't know how many of you had cell phones back in 91 but I can tell you they were pretty *beep* All of them were analog. All of them dropped calls like crazy. To have a phone call placed way underground in a bunker, to the opposite side of the Earth.....is what I call....Hollywood film making at its best.
