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.
