Writer on vacation enjoys entertaining child for director (5,6)
I believe the answer is:
orson welles
'director' is the definition.
(film director)
'writer on vacation enjoys entertaining child' is the wordplay.
'writer' becomes 'orwell' (writer George Orwell).
'on vacation' says to hollow out the word (remove centre letters).
'entertaining' means one lot of letters goes inside another.
'child' becomes 'son' (son is a kind of child).
'enjoys' with its middle removed is 'es'.
'orwell'+'es'='orwelles'
'orwelles' placed around 'son' is 'ORSON WELLES'.
'for' acts as a link.
(Other definitions for orson welles that I've seen before include "Actor" , "Colossus of the performing arts" , "Director of the film Citizen Kane" .)
