The fact that this is Metropolis can be found by a few photos of the police helicopter with the inscription "Metropolis" on its side (photos via @newmanshots, @brownknightrise, @rcar17):
At the same time, in another part of the city was seen a news vans with the inscriptions "Gotham 13 Live" and "News 8 Metropolis" (photos via @DEVLIN712 and @walstadm).
NOTE: By the way, we checked websites Gotham13live.com and News8Metropolis.com, and though they are not live as of today, the WHOIS service says these domain names were both registered by Warner Bros on 29th October, 2013. So, we are waiting for that intriguing moment when the new viral websites for Batman V Superman will appear on that addresses.
Batman-News.com reports, that they filmed a big press conference scene on Friday, revealing a story behind the giant Superman statue and explaning what Metropolis helicopter(s) and "Gothan 13 Live" van did in those scenes:
"My source on set said that they held a big ceremony to unveil the big Superman statue. The statue was built to celebrate Superman saving the Earth in the first movie — Batman v Superman: Dawn of Justice takes place about two years after the events of Man of Steel. Gotham and Metropolis news trucks and helicopters were on the scene to cover the Mayor’s speech and the statue unveiling. Elementary school kids wore “Superman Survivors” shirts and helped pull a sheet off the statue for the big reveal. They also released real doves to celebrate statue unveiling."
Batman-News.com also confirms our guesses that the new Batmobile has wings: "I’ve been told that the Batmobile doors open up like wings. I’m not sure if that means it’ll transform into a Batwing and allow Batman to fly… but with Superman and Wonder Woman confirmed for Batman v Superman: Dawn of Justice, it’d certainly make sense."
According to information available to us, today and tomorrow the crew will be working on scenes in front of the buildings with the LexCorp logo. As we can see, this location was completely ready for filming yesterday.
We don't know if Jesse Eisenberg, Henry Cavill or anybody else of the main actors will be present on the set there, but we're always keeping hope and waiting for the new pictures.
We only have confirmation that Henry Cavill and Amy Adams are in Detroit at the moment. As for Ben Affleck, who plays Bruce Wayne/Batman, he spent this week-end in Los Angeles with his family.
Batman v Superman: Dawn of Justice also stars Diane Lane, Laurence Fishburne and Jeremy Irons. The film is written by Chris Terrio, from a screenplay by David S. Goyer. Charles Roven and Deborah Snyder are producing, with Benjamin Melniker, Michael E. Uslan, Wesley Coller, David S. Goyer and Geoff Johns serving as executive producers.
Principal photography is taking place on location at Michigan Motion Picture Studios and on location in and around Detroit, Michigan; Illinois; Africa; and the South Pacific.
Set to open worldwide on May 6, 2016, Batman v Superman: Dawn of Justice is based on Superman characters created by Jerry Siegel & Joe Shuster, Batman characters created by Bob Kane, and Wonder Woman created by William Moulton Marston, appearing in comic books published by DC Entertainment.
