Okay... I never worked in a theater but i just KNOW there are multiple cameras inside ther...

Lol surprisingly ive been to cinemas that dont have cameras in it, and also there are so many cinema porn videos

also idk about other places.... but where I live, plenty of workers stand near the exits and watch the aisles xD like I know it's fiction, but I'm just sitting over here like "in what world would this ever be possible" haha

Not inside tho
