A few pictures from past Transformers sets have come up again. First up is a gallery of pictures that show the work that went into converting helicopters into the Shanghai police copters used for the Bethlehem set back in June. Below is a before, during, and after pictures but a whole lot more are at the full huge gallery here. Thanks to Mike taking and providing the pictures for us.
Spoiler-TV posted to pictures Queensway Bridge, Long Beach, CA that shows off the entire known Autobot fleet (except for the always absent Ratchet).
Thanks to an anonymous source are the two pictures of the copter used for filming Transformers 2 at Bethlehem Steel and Princeton. The first picture shows the copter as it was prepped for the its transformation into a copter for the Shanghai police force as seen in the second picture.
RodrigoNJ has posted 11 videos (found by oddsey) from the Bethlehem Steel shoot that occurred in June. The videos are short, but some do show interesting information. Specifically video proof as to why the Ice Cream Truck is speculated to be the mysterious Twins from the call sheets.
In those sheets a scene is described as "Two halves of Ice Cream Truck. One spins. Join together. Ice Cream Truck splits around Chinese kids. Leaves treat." This description is why the truck is considered an Autobot since avoiding killing kids and leaving treats is very un-Decepticon behavior. The splitting in two, demonstrating a slight difference in behavior before merging also supports the notion of two separate robots. As the videos below show, you can see two halves of the truck beside each other and in the first video you can see the right half do a spin.
Two additional videos of note is the first one that shows a scene being filmed involving pyrotechnics and weapons. Note that the weapons are either firing at something in the air or at something pretty darn tall (the Constructicon Earth Mover perhaps?). The second video shows Tyrese and Michael Bay as they joke and are generally friendly with fans near the trailers.
