Stuntman struggling duly boobed (4,6)
I believe the answer is:
body double
'stuntman' is the definition.
(body double for an actor)
'struggling duly boobed' is the wordplay.
'struggling' indicates an anagram (the letters struggle or wriggle into a new form).
'duly'+'boobed'='dulyboobed'
'dulyboobed' anagrammed gives 'BODY DOUBLE'.
(Other definitions for body double that I've seen before include "Stand-in film actor for stunt or nude scenes" , "that's not quite right, on the face of it" .)
