" Did anyone read the book? Did Swofford say he was there or did the filmmakers add it?"
I read the book (it sucked since he was writing it for the Move On crowd). If I understand the scene you're talking about, he claimed he was watching a video from home with a bunch of other Marines when one of the Marines recognizes either his home or an identifying feature on the woman (can't remember which). The Marine in question ran crying from the room.
Screw this movie. I'm waiting for "Generation Kill", a far superior effort.
I never read the book on the recommendation of a good buddy who did and said it was absolute BS.
I wish I hadn't seen it! I should have known that the only war movie that Hollywood would produce during the Bush years would be an anti-military, anti-American film. (Mel Gibson's is an exception because he has his own company and doesn't depend on the Hollywood crowd to produce it)
