Pretty sure that "Willy Wonka & the Chocolate Factory" is the kid's version of "Saw".

Willy Wonka and the Chocolate Factory (1971) A bunch of freeloaders lie around in bed & support themselves by violating child labor laws.

parent: why did you do this to my child willy wonka: well you see they tried to eat some chocolate on a tour of a chocolate factory they won

If Willy Wonka manufactured anything other than candy that movie would just be a dark tale of a negligent factory owner murdering children.
