Before it's "lights, camera and action," the key word is "notification."
The number of film and television productions that are shooting in the city is on the increase. The NYC Mayor's Office of Media and Entertainment reports nearly 200 films have been shot in the city between January and August 2015 and that's on track to exceed 2014.
46 shows are being shot for the 2014-2015 television season.
They can be seen and heard around the city and permits are required for certain activities.
Residents reported hearing a loud explosion in the Bronx Wednesday. The Office of Emergency Management said it was related to a film shoot for a new TV show called "Blindspot."
The production had permits to shoot and for a simulated explosion at a lot on Alexander Avenue near E. 132 Street. Two signs were posted on the street, but neighbors were still caught off guard.
Across the river in Manhattan, David Carlos heard and felt the blast. He recorded video of the smoke and posted it on twitter. News organizations contacted him and another twitter user advised him of the scheduled event.
NYC OEM announced the simulated explosion would happen between 9 a.m. and 1 p.m. The agency issues tweets about scheduled production work across the five boroughs.
"New York City is increasing becoming a year-round television town," says a representative from the Office of Media and Entertainment. "Cable, digital and network series have new seasons starting throughout the year."
The industry is also an important employer in the city.
