Transformers 4 finished its first weekend of filming in Chicago and by all appearances it was an exciting one with most of the core cast showing up, explosives set off, the Autobot vehicles on display, and more. Most of the Saturday and Sunday filming involved filming inside of buildings so not as much for the public to see but there are still some photos. The pics show the first time Kelsey Grammer has been seen on a Transformers 4 set.

They also give us a look at the Autobot vehicles, Stanley Tucci, his character's 3 assistants (Melanie Specht, Abigail Klein, and Victoria Summer), Kelsey Grammar, and Mark Wahlberg. To view the full galleries of images from this weekend, click the links below. Also below is a video found by Feris O. of the Autobot vehicles when they were in Detroit. Its a few weeks old but gives you a nice long look at the cars.

Update: Another gallery link has been added along with videos (via Seibertron) below that include an up close look at "Propaganda Wall" on Columbus Drive.
