Producers of HBO's "Boardwalk Empire" graciously lent their Greenpoint set to the NYPD Wednesday so that cops could conduct hostage drills in the fake 1920s setting.
The New York Post reports the exercise used NYPD cadets to act as hostage victims inside the set's Ritz Carlton Hotel.
The Emergency Service Unit swept in via helicopter, saving the hostages from six pretend terrorists, and providing a happy, Hollywood ending.
The drill was part of a wider training initiative created after 2008's deadly hostage situation in Mumbai.
The horrific attack left more than 160 dead throughout India's largest city.
