Why is it forbidden? (Is it distracting and rude or dangerous? Or a third thing I haven’t thought of?)
That was just intended to be a joke. King Kong breaks loose and goes on his rampage when they take flash photos of Ann (Fay Wray) at the theatre. I didn’t know this because I’d never seen any of the movies.
IRL, it is distracting, rude, and can be dangerous for the actors. But I kinda like the idea that an actor might just go insane from the flash, grab their one true love, and rampage through the city.
