Disney? No actors messed around with it! (10)
I believe the answer is:
cartoonist
'disney?' is the definition.
Both the definition and answer are singular nouns.
Maybe you can see a link between them that I can't see?
'no actors messed around with it' is the wordplay.
'messed around with' indicates an anagram (I've seen 'messing around' mean this).
'no'+'actors'='noactors'
'noactors' mixed up with 'it' makes 'CARTOONIST'.
Can you help me to learn more?
(Other definitions for cartoonist that I've seen before include "Eg, Peter Brookes" , "Low" , "drawer" , "Heath Robinson, say" , "Strip artist?" .)
