Actor-director Welles (5)
I believe the answer is:
orson
'actor-director welles' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for orson that I've seen before include "- - Welles (films)" , "-- Welles, director/actor" , "Film director so-called" , ". . . . . Welles, creator of film ''Citizen Kane''" , "- - Welles (actor)" .)
