The Transformer 2 Movie Chronicles reports "OK Well I work in the area and they have the whole area set up to be China, as you guys know. Now I did see Prime, Bumblebee, the silver corvette, 2 blue cars (small) and Ironhide. All were parked on the back lot behind Catalina Landing!

The scene I witnessed was a traffic scene where they were driving down Shoreline Drive and then 2 flatbed Trucks merge into traffic. THEN BOOOM!!! One of the two trucks blew in half."

Catch all the action when Transformers: Revenge of the Fallen hits theaters June 26. 2009.
