Someone has posted some photos of early set preparation in Bethlehem, Pennsylvania along with some interesting info:
New concept car, eh? Could this be a new character, or one of the surviving TFs getting an upgrade (which I hope they don't do for continuity sake) ? Maybe one of those Blackhawks are more than meets the eye?- The east side of the site is being re-developed so most of the shooting will take place on the west side.
- A new concept car (possible Transformer?) not used in the first movie will be used there
- Two Blackhawk helicopters will be used
- The area will be patrolled by the site security and Bethlehem City Police who will also and close streets for the shoot.
We'll have to wait and see!
