Willy Wonka & the Chocolate Factory (1971)
Gene Wilder doesn’t show up until 44 minutes into the movie, so I recommend just skipping past the first 44 minutes.
Five children tour Willy Wonka’s psychedelic candy factory, but four of them are brats and suffer horrible fates related to their brattyness. After each horrible fate, the rather creepy Oompa Loompas (you sort of get the feeling that they’re slave labor) sing a song in which they give wise advice, such as don’t chew gum, and read a book instead of watching TV.
Charlie is supposedly the good honest kid (even though he also misbehaved during the factory tour) and is rewarded with the entire chocolate factory, which Willy Wonka will train him to take over. There’s no explanation as to why Willy Wonka couldn’t marry a nice woman and have his own kid.
Rated G in 1971, but probably not suitable for today’s precious snowflake children. In fact, it makes one guy’s list of top ten kids’ movies not appropriate for kids. But that’s why all children of my generation remember this movie, while other movies we watched as kids are pretty much entirely forgotten. Maybe we need more movies where children are scared into behaving.
