Not shortened, as a film (5)
I believe the answer is:
uncut
'not shortened as a film' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for uncut that I've seen before include "the whole pack" , "diamonds, originally" , "Without abridgement" , "(Film) full length; (book) impossible to open" , "Complete, unabridged" .)
