Damaged steel cases about film studio (7)
I believe the answer is:
elstree
'film studio' is the definition.
'Elstree' can be an answer for 'studio' (Elstree Studios, British film and TV studios). I am not certain of the 'film' bit.
'damaged steel cases about' is the wordplay.
'damaged' indicates anagramming the letters.
'cases' means one lot of letters goes inside another (forms a case around).
'about' becomes 're' (regarding).
'steel' is an anagram of 'elste'.
'elste' going around 're' is 'ELSTREE'.
Can you help me to learn more?
(Other definitions for elstree that I've seen before include "Place for filming" , "Where films were made" , "Studio location" , "Hertfordshire place associated with film studios" , "Film studios to N. of London" .)
