Hitchcock made several films that should place in the top ten, but here we will merely cheat and place three in the seventh slot: Rear Window, North By Northwest, and Psycho.
Evil may be irrational, but it is the norm in this world we live in. It can live right next door, or for that matter even in us. (For this see Vertigo another great Hitchcock film.) Hitchcock’s films are fear inducing, not in a shock filled, mindless, roller coaster ride sort of way, but rather in the thought provoking reality of evil they portray.
