Kevin Dunn Back For Transformers 2; New Philly Shoot Info

It was a busy day for "Transformers 2: Revenge of the Fallen" yesterday, including Kevin Dunn being spotted on the set during the shoot at the University of Pennsylvania, and new information about what's going to happen in the film.

There has not been any information regarding the return of Sam Witwicky's parents, Ron and Judy Witwicky, until now. Movie blog The Faded Silver Screen reports that Mr. Dunn was on the Penn set and has provided some images of him signing autographs for fans who were nearby.

Judy Witwicky, portrayed by Julie White in "Transformers," was not spotted on set.

Eyewitness reports that the scene being filmed at the Quad depicted move-in day for the University.

DT, a website that blogs about the goings-on at UPenn, has an image of Shia LaBeouf on set wearing a green shirt with the symbol commonly associated with recycling. The eyewitness report says that he was also carrying a green purse. What that means, is unknown.

Following up with images from yesterday, the source that sent looks of the mystery car spotted at the Laurel Hill Cemetery, has sent more to the Transformers Live Action Movie Blog. The images give a great look at the production-ready 2010 Chevrolet Camaro and the Peterbilt truck that serves as Optimus Prime's alternate mode.

The differences between the concept and the production-ready versions featured in the film are immediately apparent, including a different grille and paint applications in certain places. The color of the vehicle also looks more gold than yellow.

On top of those images, "MirrorMind" of Monster Mania has some images of the UPenn shoot. The images do not show anything particularly revealing, only images of the crew prepping for the day's shoot, Director Michael Bay, and the back of Shia LaBeouf's head, who was wearing the same green shirt as described above.

According to the eye-witness description that accompanied "bp"'s images, the film crew also made a presence at Kelly Drive for a chase scene, and at the Eastern State Penitentiary.

Megan Fox was reportedly on-site at the Kelly Drive shoot, which is in the same section as the Laurel Hill Cemetery, where the vehicles were spotted yesterday.

There was no further information on the prison shoot.
