Quiet film actor (6)
I believe the answer is:
player
'actor' is the definition.
(synonyms)
'quiet film' is the wordplay.
I cannot quite understand how this works, but
'quiet' could be 'p' (music symbol for 'piano', ie soft or quiet) and 'p' is present in the answer.
'film' could be 'layer' (I've seen this before) and 'layer' is found within the answer.
No letters remain.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for player that I've seen before include "Participant in competitive game" , "Actor - footballer?" , "Actor; sportsman" , "Active sportsperson" , "South African golfer, Gary" .)
