NYPD crash from The Amazing Spiderman 2
Right here in Rochester, NY, filming is going on now for a big NYC chase scene for next summer's The Amazing Spiderman 2. I was able to stop in on the one day that they took a break and get pretty close to the cars, including this big three-car pileup.
A close examination will show the ramps that are on the rear of the first two cop cars, to enable the following cars to ride up the back up the car ahead of them, ripping up the roof in the process. Cool stuff!
There are a bunch more photos over at Google+:
