The Morning Call have revealed that Bethlehem’s filming shall be at a steel works, a highly mechanized and perfectly suited backdrop:

Try to imagine giant, extraterrestrial robots disguised as tractor-trailers on Route 22 or camouflaged among the towering Bethlehem Steel blast furnaces.

A film crew from ”Transformers 2” will bring those shape-shifting robots to life in south Bethlehem next month for a movie scene in front of the iconic furnaces.

Of course, no one will see the robots because they’re computer-generated. But anyone will be able to see the action at the old Steel site as the filmmakers transform it into a fictional Chinese city populated by people from the Lehigh Valley.

[...]

The movie crew will film in Bethlehem during the first week of June and will use the blast furnaces as the scene’s backdrop, Callahan said.

According to an announcement from Heery Casting of Philadelphia, the filmmakers hope to cast local ”Asian men and women, boys and girls, ages 7 [to] 65” as paid extras in the movie. In particular, the crew hopes to recruit extras of Asian descent who have military backgrounds.
