Recent disturbance 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 am unsure of the 'actor's' bit.
'recent disturbance about an' is the wordplay.
'disturbance' is an anagram indicator.
'about' is an insertion indicator.
'recent' is an anagram of '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 - hypnotise" , "Enrapture; door" , "doorway" , "Enchant" , "Charm - one's way in" .)
