Some Northern Ireland actors get depressed (8)
I believe the answer is:
downcast
'depressed' is the definition.
(I know that depressed can be written as downcast)
'some northern ireland actors' is the wordplay.
'some northern ireland' becomes 'down' (I can't justify this - if you can you should believe this answer much more).
'actors' becomes 'cast' (group of actors).
'down'+'cast'='DOWNCAST'
'get' is the link.
Can you help me to learn more?
(Other definitions for downcast that I've seen before include "disheartened" , "Sad" , "Feeling despondent" , "Depressed - looking at the floor?" , "blue" .)
