Some filming occurred at 35 East Wacker Drive, specifically the Jeweler's Building which is described as playing "a significant role in the last part" of the film. The articles mentioned that in its first few years of existence (circa 1881) it had car sized elevators at street level for security reasons. After all leaving your car then made you more vulnerable. The article just drops in this historical anecdote for some reason so figure it might become useful once see the film.
In regards to Shockwave, the article indicates he does not have any lines in the film but instead use his eye and mouth to convey emotion. NYT wrote:
Shockwave, designed and animated by Industrial Light and Magic, rises about 40 virtual feet and has more than 2,000 moving digital pieces. “He doesn’t stand around and talk,” Mr. Farrar said. “He just fights.” Shockwave took the animators about 30 weeks to build before he was ready to be added to a shot.
“The eyes are critical and the mouth is critical,” he said. “If you can’t read those, you can’t understand what the character is doing or portraying. You have to read Shockwave through just the emotions of the face, almost like a silent-era movie star.” For this reason Mr. Farrar and his team sought to make Shockwave’s eye appear as real as possible, with a lens, a moving iris and a light inside that can oscillate.
