Willy Wonka And The Chocolate Factory
While Tim Burton used his permanent retainer on Johnny Depp to get him to play Willy Wonka, nothing tops the original Willy Wonka & the Chocolate Factory, starring Gene Wilder as the candy mogul.
Apart from traumatizing generations of children with that tunnel sequence, the movie also featured The Candy Man, a song that would later become a hit.
Speaking of hits, while the creepy candy store clerk lifts the hatch to let the kids ransack his store like barbarians, he visibly smacks a little girl in the chin. Undeterred, she shakes it off and charges towards early-onset diabetes.
