Oscar-winning film produced in Australia (7)
I believe the answer is:
amadeus
'oscar-winning film' is the definition.
I can't judge whether this definition defines the answer.
'produced in australia' is the wordplay.
'produced' becomes 'made' ('make' can be a synonym of 'produce').
'in' indicates putting letters inside.
'australia' becomes 'Aus' (abbreviation).
'made' placed inside 'aus' is 'AMADEUS'.
Can you help me to learn more?
(Other definitions for amadeus that I've seen before include "See 12" , "Mozart's second name" , "P. Shaffer's Mozart play" , "Film/play life of Mozart" , "Biopic" .)
