Time Out says
Blackmail marked Hitchcock's first use of sound, and it remains famous for its innovations in that area. But it's now more stimulating for its experiment with narrative structure: an efficient, impersonal police investigation that elides into a messy, personal story of attempted rape, murder in self-defence, blackmail and chase to the death.
