A quick question.
Do you write establishing shots?
I've seen some scripts that do and some that dont.
I have a tendency to put everything in a script. Do you take the trouble to describe opening shots? and exterior, passage-of-time, shots? or do you leave that to the film makers?
As others have said, it's about clarity and expediency. If you think an establishing shot helps to clarify your storytelling then put it in. But if you can take it out and reads fine without it - the reader still understands what's happening - then you don't need it.
We get establishing shots all the time in films - the White House is a classic one, as is the helicopter panoramic of the Pentagon - but they tend to be editorial choices rather than script and pacing choices. Although we can read in the script-
INT. SITUATION ROOM, PENTAGON - NIGHT
-that we are in the Pentagon, an audience watching the film won't know without either an establishing shot, a title card or even both.
My favourite establishing shots are the ones that clearly require no title card but end up having one anyway, like a shot of the Egyptian pyramids with, "Cairo, Egypt" super-imposed or a red double decker bus going over Tower Bridge behind a black cab with Big Ben, the Houses of Parliament and the Tower of London in the background with the helpful caption of, "London, England"over the top of it.
