Suffering — Oscar-winning film, by the way, gets another award (9)
I believe the answer is:
martyrdom
'suffering' is the definition.
(martyrdom is suffering for a higher cause)
'oscar-winning film by the way gets another award' is the wordplay.
'oscar-winning film' becomes 'marty' (winner of Academy Award for Best Picture in o956).
'by' is a charade indicator (letters next to each other).
'the way' becomes 'rd' (short for road).
'gets' says to put letters next to each other.
'another award' becomes 'om' (order of merit. I am not sure about the 'another' bit.).
'marty'+'rd'+'om'='MARTYRDOM'
(Other definitions for martyrdom that I've seen before include "Death for one's beliefs" , "suffering" , "Death of one dying for their religion" .)
