Overview:

Nares mocks up Ancient Rome by shooting in faux-classical sites including Tribeca's American Thread Building, where a decrepit penthouse loft with a peeling-paint dome serves as an echoey stand-in for the imperial palace. The latter location required ingenuity: Posing as potential renters, Nares and associates asked the manager to show them the apartment, then unlocked the windows on the way out; a few hours later, they broke back into the space, full cast and crew in tow, to shoot the necessary scenes.
