Scriptwriter moving actress in (9)

I believe the answer is:

scenarist

'scriptwriter' is the definition.
(thesaurus)

'moving actress in' is the wordplay.
'moving' is an anagram indicator.
'actress'+'in'='actressin'
'actressin' anagrammed gives 'SCENARIST'.

(Other definitions for scenarist that I've seen before include "Deviser of drama" , "Author" .)

I've seen this clue in The Telegraph.
