Spot on which films are made (8)
I believe the answer is:
location
'spot' is the definition.
(I've seen this before)
'on which films are made' is the wordplay.
I cannot really see how this works, but
'on' could be 'at' (I've seen this in other clues) and 'at' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for location that I've seen before include "Position,place" , "Place, site" , "Setting" , "Position, point in space" , "Position or situation" .)
