Managed rising artist moving into storytelling (9)
I believe the answer is:
narration
'storytelling' is the definition.
(I've seen this before)
'managed rising artist moving into' is the wordplay.
'managed' becomes 'ran' (I've seen this before**).
'rising' shows that the letters should be reversed in order (going up in a down clue).
'artist' becomes 'ra' (Royal Academician, member of Royal Academy of Arts).
'moving' indicates anagramming the letters.
'ran' written backwards gives 'nar'.
'into' with letters rearranged gives 'tion'.
'nar'+'ra'+'tion'='NARRATION'
(Other definitions for narration that I've seen before include "Spoken account" , "Story" , "Process of storytelling" , "Voice-over in film" , "Account of events" .)
