Director, in extremis, fought to secure financial backer for film (2,11)
I believe the answer is:
dr strangelove
'film' is the definition.
(I have seen 'satirical film' mean 'dr strangelove' so perhaps 'film' could also mean 'dr strangelove')
'director in extremis fought to secure financial backer' is the wordplay.
I cannot quite understand how this works, but
'director' could be 'd' and 'd' is located in the answer.
'backer' could be 'angel' (synonyms) and 'angel' is located in the answer.
This explanation may well be incorrect...
'for' is the link.
Can you help me to learn more?
(Other definitions for dr strangelove that I've seen before include "Peter Sellers film role" , "satirical film" .)
