Filming takes place here, in genteel street (7)
I believe the answer is:
elstree
'filming takes place here' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'in genteel street' is the wordplay.
'in' indicates a hidden word.
'ELSTREE' is hidden within 'genteel street'.
Can you help me to learn more?
(Other definitions for elstree that I've seen before include "Studio location" , "Place for filming" , "establishment producing presentable features" , "Where films were made" , "Hertfordshire place associated with film studios" .)
