Mental floss has a pretty interesting piece on Song of the South, the Disney movie that the characters from the ride Splash Mountain originate in (as well as the song Zip-a-dee-do-dah). It’s truly an interesting situation: popular franchise characters in a movie that hasn’t ever been released on home video in the US for fairly obvious reasons. If you’re scratching your head going “I’ve never heard of that movie..” Take a read and think about how we sorta forget that things we still see evidence of today were interpreted differently 70 years ago.

(PS: I’m composing this on my iPhone, and Autocorrect almost turned the title of this piece into Allah Mountain. How it got Allah from Splash, I have no idea!)
