Novello of old films (4)
I believe the answer is:
ivor
'novello of old films' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ivor that I've seen before include "Welsh actor, composer, singer" , "-- Novello, composer and actor" , "Man" , "__ Novello, Welsh composer and songwriter, d. 1951" , "Online engine" .)
