Filming locations (4)
I believe the answer is:
sets
'filming locations' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for sets that I've seen before include "Classes" , "Major divisions of tennis match" , "Scenery etc. of 11 across productions" , "Groups of things of the same kind" , "Units of play in tennis" .)
