What's going on?
I would say, for Slug lines, aka EXT. STREET - NIGHT, etc... you will want to differentiate which street this is...
The reason for this has to do with the Production schedule (VERY important in making a film)...you're going to want to plan out locations, days, who can be there/who cant, etc, as best as possible
Your crew, actors, etc, will need to know WHICH street you are talking about, if you have two totally different scenes that happen outdoors, at night, but on two different streets... because that makes it two different locations...just for planning purposes, you'd need to be a little more specific
I would think it would be OK in the script to put the actual NAME of each street down, like "EXT-OAK STREET-NIGHT" and then "EXT-GREEN STREET-NIGHT" etc, just to differentiate... the main thing is that you'll need to plan out locations, so that you can get as much shooting done at that one location as you can...so any scene that happens on a certain street at night should be filmed that night, up to about 5-6 pages of script...I think 6 pages per shooting day is the SAG Union limit that actors can do-
If I'm wrong on any of this folks correct me, but to me, that would be a solution
