Dogmatic director in a recasting (11)
I believe the answer is:
doctrinaire
'dogmatic' is the definition.
(thesaurus)
'director in a recasting' is the wordplay.
'recasting' is an anagram indicator.
'director'+'in'+'a'='directorina'
'directorina' anagrammed gives 'DOCTRINAIRE'.
(Other definitions for doctrinaire that I've seen before include "not practical" , "Seeking to impose a view" , "Impractical theorist" , "Opinionated" , "Inclined to follow principles to unworkable extremes" .)
