Willy Wonka & The Chocolate Factory

The neon-skinned Oompa Loompas were creepy, and I used to get really stressed out about Violet Beauregarde's transformation into a blueberry, but the truly terrifying part of this childhood classic was that infamous LSD-fueled boat ride through the chocolate factory tunnel. Narrated by a psychopathic Willy Wonka and featuring a video montage of death, destruction, and perversion, it's unforgettable. And not in a good way.
