Residents of Philadelphia were in for a surprise last weekend when they saw helicopters with FBI written across them zooming above the PNC Bank Building.

What's more there were even quite a few SWAT officers who made a dramatic entry, suspending themselves from the aircraft carrying rifles. Just as localites began to worry if there was a panic situation on hand, did they see a film crew with cameras et al shooting this whole scenario.

This was not any hostage attack or terrorist threat but the shooting of Yash Raj Films' upcoming project New York (working title) which was in progress in the busy and central area of Philadelphia.

The film's stars, namely John Abraham, Katrina Kaif and Neil Nitin Mukesh, were present as the crew along with director Kabir Khan filmed some action scenes in and around the PNC Bank Building.

While New York has been quite a prominent feature of many a Bollywood films, this was a relatively new experience for the residents of Philadelphia who after initially getting a trifle scared seemed to enjoy the most of this Bollywood film shoot.
