Wow, I never knew that Disney did serious political stuff. Or trippy, scary stuff (the last 2 mins of that clip was creepy). I wouldn't be surprised by Warner Bros (as Zarcon mentioned) or Tex Avery, but Disney... well maybe it just shows how downhill Disney's animation has gone into the realm of kiddyproofing recently (not saying that anything like this should be made today* cause it shouldn't, just that it's a big jump from this to the kind of films they make now)
[Edit] *Or rather, made today for widespread public release. Internet animators and specialist film communities can get away with it, but screening on TV in prime time is a different matter.
