Actor in Powell & Pressburger's first film (6)
I believe the answer is:
player
'actor in powell' is the definition.
'player' can be an answer for 'actor' (synonyms). I am not sure about the 'in powell' bit.
'pressburger's first film' is the wordplay.
'pressburger's first' becomes 'p' (1st letter of 'pressburger').
'film' becomes 'layer' (film can mean a thin layer of something).
'p'+'layer'='PLAYER'
Can you help me to learn more?
(Other definitions for player that I've seen before include "powerful participant" , "Sports team member" , "Active sportsperson" , "Performer" , "Participant in competitive game" .)
