Film enemy stealing wild goat (7)
I believe the answer is:
footage
'film' is the definition.
(footage is a kind of film)
'enemy stealing wild goat' is the wordplay.
'enemy' becomes 'foe' (synonyms).
'stealing' is an insertion indicator.
'wild' indicates anagramming the letters.
'goat' is an anagram of 'otag'.
'foe' placed around 'otag' is 'FOOTAGE'.
(Other definitions for footage that I've seen before include "quantity shot" , "Piece of filmed material" , "Part of film" , "Film that has been shot" , "Length of film" .)
