All I remember about Vertigo as a kid in 1958 was the TV plug with the bulging staring eye that turned into the rotating vortex that got closer and closer and the creepy neenie noo nee music. Gave me nightmares (the worst ones ever since always involve one big eye).
Then I saw the movie as an adult. It was a letdown, I was expecting Vincent Price gooseflesh instead all I can recall is a series of anguished expressions and little action.
Oh, well.
The bulging eye is creepy. But the second when she subtly purses her lips is just as creepy.
