Film set at the Bates Motel (6)
I believe the answer is:
psycho
'film set at the bates motel' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for psycho that I've seen before include "Chopsy (anag.)" , "Method of treatment pioneered by Freud" , "Prefix denoting the mind or soul" , "Hitchcock's 1960 thriller" , "Well-known Hitchcock film" .)
