Re: Pepper Potts as Rescue
The snow scene takes place around Chattanooga, TN. We saw that during filming in Wilmington.
The shot of Pepper above is probably part of the Grauman Chinese Theater attack. I'd say that happens early in the movie, and the Malibu mansion assault happens later, probably around midpoint. Tony probably then embarks on a solo journey cross-country, with nowhere left to go, nobody left from his support network (yes, I'm betting 1000 Internet Bucks that both Happy *and* Pepper are dead by this point), he's wrongly accused of crimes he did not commit and has become an outlaw, and the only way he can clear his name is to find out who's destroyed his world.
That plot would be very, very, very Shane Black.
