Hitchcock film extremely cut? Time I quit (7)
I believe the answer is:
vertigo
'hitchcock film' is the definition.
(Alfred Hitchcock film)
I don't understand how the remainder of the clue works.
(Other definitions for vertigo that I've seen before include "Dizziness due to disorder in sense of balance" , "Dizzy sensation brought on by heights" , "Sensation of dizziness brought on by heights" , "Disturbance in the inner ear" , "that makes it hard to stand" .)
