'shocking director' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'father child at work with mate' is the wordplay.
'at work' indicates an anagram.
'with' means one lot of letters go next to another.
'mate' becomes 'cock' (both are terms of affection).
'father'+'child'='fatherchild'
'fatherchild' with letters rearranged gives 'alfredhitch'.
'alfredhitch'+'cock'='ALFRED HITCHCOCK'
