Director of celestial conflicts, by George! (5)
I believe the answer is:
lucas
This clue could be a double definition.
'director of celestial conflicts' is the first definition.
The definition suggests a singular noun which matches the answer.
'george' is the second definition.
Both the answer and definition are singular nouns.
Maybe they are linked in a way I don't understand?
'by' is the link.
Can you help me to learn more?
(Other definitions for lucas that I've seen before include "George --, creator of Star Wars" , "George -, US film director (Star Wars)" .)
