Recent uproar about an actor's appearance (8)
I believe the answer is:
entrance
'actor's appearance' is the definition.
'entrance' can be an answer for 'appearance' (both can mean an arrival). I'm not sure about the 'actor's' bit.
'recent uproar about an' is the wordplay.
'uproar' is an anagram indicator.
'about' is an insertion indicator.
'recent' anagrammed gives 'entrce'.
'entrce' going around 'an' is 'ENTRANCE'.
Can you help me to learn more?
(Other definitions for entrance that I've seen before include "Way in - fascinate" , "Fill with wonder, door" , "An actor's coming on stage" , "Carry away" , "Enrapture; door" .)
