Appears in: The Wizard of Oz (1939)
Scariest moment: Caught in a cyclone, Dorothy (Judy Garland) cowers as the Wicked Witch flies by on her magic broom, cackling all the way into viewers' nightmares.
Weakness: Physical contact with water. Seriously.
Not unlike Willy Wonka and the Chocolate Factory, The Wizard of Oz is one of those family films that leaves astute viewers wondering how little kids could ever watch it without crying for mommy. Chiefly responsible for such a reaction is the Wicked Witch of the West (Margaret Hamilton), the evil fantasy world version of Miss Almira Gulch, who demands that little protagonist Dorothy's dog, Toto, be taken away after the pooch bit Miss Gulch.
Whenever she talks, the Wicked Witch's voice seeps into one's brain, with its shrill pitch typically followed by that cackling, demonic laugh. Hamilton's nightmarish creation doesn't even need to open her mouth, though, in order to instill unease—her pointy nose, long fingers, and devilish eyes tap directly into children's fears of witches, those unwelcoming old hags who dominate Halloween decorations yearly.
