Unusually, he films that very bloke (7)
I believe the answer is:
himself
'very bloke' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'unusually he films' is the wordplay.
'unusually' indicates an anagram.
'he'+'films'='hefilms'
'hefilms' anagrammed gives 'HIMSELF'.
'that' acts as a link.
Can you help me to learn more?
(Other definitions for himself that I've seen before include "with whom poor Brutus was at war?" , "head of Irish household" , "Flemish (anag.)" , "Male reflexive word" , "He films (anag.)" .)
