Hitchcock film: hard copy’s edited (6)
I believe the answer is:
psycho
'hitchcock film' is the definition.
(1960 film directed by Alfred Hitchcock)
'hard copy's edited' is the wordplay.
'hard' becomes 'h' (abbreviation used in pencil classifications).
'edited' is an anagram indicator.
'h'+'copys'='hcopys'
'hcopys' anagrammed gives 'PSYCHO'.
(Other definitions for psycho that I've seen before include "Loony" , "In brief, person with severe mental disorder - ask Alfred Hitchcock" , "Method of treatment pioneered by Freud" , "Hitchcock classic" , "Well-known Hitchcock film" .)
