Where many films are made with family member (2-3)
I believe the answer is:
in-law
'family member' is the definition.
(I know that in-law is a type of family member)
'where many films are made with' is the wordplay.
I cannot quite understand how this works, but
'many' could be 'l' and 'l' is located in the answer.
'are' could be 'a' (short for 'are', historical unit of measurement) and 'a' is found within the answer.
'with' could be 'w' (abbreviation) and 'w' is found within the answer.
The remaining letters 'in' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for in-law that I've seen before include "Near relative" , "Meghan to Harry's family?" , "Relative by marriage" , "Spouse's relation" , "Relation by marriage" .)
