Time engineers put into different film-making location (7)
I believe the answer is:
elstree
'film-making location' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'time engineers put into different' is the wordplay.
'time' becomes 't' (abbreviation).
'engineers' becomes 're' (Royal Engineers).
'put into' indicates putting letters inside.
'different' becomes 'else' (synonyms).
't'+'re'='tre'
'tre' placed inside 'else' is 'ELSTREE'.
Can you help me to learn more?
(Other definitions for elstree that I've seen before include "Studio location" , "Film studios to N. of London" , "establishment producing presentable features" , "Where films were made" , "Place for filming" .)
