Look over small quantity of film (4)
I believe the answer is:
scan
'look over' is the definition.
(I've seen this in another clue)
'small quantity of film' is the wordplay.
I cannot really see how this works, but
'small' could be 's' (abbreviation - e.g. clothes size) and 's' is found in the answer.
'quantity' could be 'can' (can is a kind of quantity) and 'can' is found within the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for scan that I've seen before include "Hercule ---, detective" , "Look over cursorily" , "Traverse with a detector" , "Conform to rules of poetic metre" , "Study systematically" .)
