Actually ..I kinda see what you are saying...however there is something interesting going on in the effects rendering. What I thought was lasers glancing on the other characters was actually debris blowing in the air. If you look at the debris blowing in front of Brody, it looks as if some of it actually picks up light. At first I thought this was film noise, but knowing RR's fondness for shooting digital, I would rule that out. Again..everything we discuss is all speculation ( one of the joyful things in anticipation of the film) I can tell you, having read many screenplays that that was not a shooting script. It was nowhere near ready for a line producer to breakdown.
Good eye. This film is still in edit even as the trailer comes out. Who knows how the final effects will look. Anybody remember the very CGI looking Iron man in the initial IM 1 trailer...and then how much better he looked in the film.
Either way ..the editing on the trailer was very good. Loved how the red laser served as a visual representation of a heartbeat when inter-cutting the scenes
