Noble actor is oddly consumed by method (10)
I believe the answer is:
aristocrat
'noble' is the definition.
(thesaurus)
'actor is oddly consumed by method' is the wordplay.
'oddly' indicates an anagram.
'consumed by' indicates putting letters inside.
'method' becomes 'art'.
'actor'+'is'='actoris'
'actoris' is an anagram of 'istocra'.
'istocra' put inside 'art' is 'ARISTOCRAT'.
(Other definitions for aristocrat that I've seen before include "What's listed in Debrett" , "Nobleman" , "Member of the nobility" , "Nob" , "Member of the upper class" .)
