Ok, creepy, not scary. Let's try in the order that I saw them:
"Wizard of Oz" - flying monkeys, 'nuff said
"Invasion of the Body Snatchers (56) - had nightmares about pods for a while after seeing that one
"Freaks" - creep-O-rama
"Repulsion" - Polanski weirdness
"The Exorcist"
"Jaws" - not during the movie and it's a stereotype, but I'd think about it swimming in lakes in South Dakota for months after!
"Candyman"
"Hellraiser"
"Audition" - japanese creeptastic
