Always upset about end of brave deceased actor (5)
I believe the answer is:
reeve
'actor' is the definition.
(I have seen 'Comic actor' mean 'reeve' so perhaps 'actor' could also mean 'reeve')
'always upset about end of brave deceased' is the wordplay.
'always' becomes 'ever' (synonyms).
'upset' is a reversal indicator.
'about' is an insertion indicator.
'end of brave deceased' becomes 'e' (I am not sure about this - if you are sure you should believe this answer much more).
'ever' in reverse letter order is 'reve'.
'reve' going around 'e' is 'REEVE'.
Can you help me to learn more?
(Other definitions for reeve that I've seen before include "The bailiff to run a rope through" , "Old English magistrate or bailiff" , "Anglo-Saxon official" , "Thread (rope) through a ring, old official" , "High official" .)
