Film-maker possibly approached artist (6)
I believe the answer is:
camera
'film-maker possibly' is the definition.
'approached artist' is the wordplay.
'approached' becomes 'came'.
'artist' becomes 'ra' (Royal Academician, member of Royal Academy of Arts).
'came'+'ra'='CAMERA'
(Other definitions for camera that I've seen before include "Common recording device for pictures" , "An image-capturing device" , "TV studio item" , "optical device" , "Way of making pictures" .)
