Animated Child Catcher of UK’s ultimate auteur (6,9)
I believe the answer is:
alfred hitchcock
'auteur' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'animated child catcher of uk's ultimate' is the wordplay.
'animated' is an anagram indicator.
'ultimate' suggests the final letters (the last or ultimate letter).
The final letter of 'uk' is 'k'.
'child'+'catcher'+'of'='childcatcherof'
'childcatcherof' is an anagram of 'alfredhitchcoc'.
'alfredhitchcoc'+'k'='ALFRED HITCHCOCK'
Can you help me to learn more?
(Another definition for alfred hitchcock that I've seen is " English-born film director".)
