As you may already know, Transformers 2 is currently filming in and around Philadelphia, most notably at a University of Pennsylvania frat house and at a student dorm building known as the Quad. I was lucky enough to pass by both locations, and snap a few pictures.
Here is Michael Bay as he is leaving the Quad after a long day of shooting:
Mr. Bay was kind enough to sign autographs and chat briefly with fans who had been waiting outside in the hot sun for at least half an hour.
Here is Kevin Dunn, who plays Sam Witwicky's father in the film:
This is the U. Penn frat house known as "The Castle." Crew have spent the last two days here setting up lights, equipment, and props, getting ready for shooting to take place.
Lastly, here's a close-up of the sign on the frat house, a decoration for one of the movie's scenes.
Note: An anonymous source informed me that they are no longer using the graffiti banner for any frat house scenes. Also, another person claims that the graffiti banner is actually left over from a party that took place at the frat house during the semester. (Director Michael Bay opted instead to use a fraternity flag above the front entrance.)
