I saw this on http://artofakira.com/
I've not had any animation shit on here before, but it's film related. And I have seen about 3 Disney movies in my life so anything showing it in not so bright a light is more interesting than anything else to me. This is very well edited showing the recycled scenes.
There's another little clip posted about this going on in Disney animated films, but not as creative as the first. Looks like some sort of TV documentary or something
