We've watched our favourite Disney movies so many times that we can recite the entire script.
But if you get deja vu when watching
Cinderella, it might not be because you've watched it 150 times (although that is probably a large part of it.)
It could be down to recycled animation.
This video shows how animators use the same footage for different movies, simply drawing the new characters over the old template - particularly in dancing scenes.
Some of our absolute faves like
Snow White,
Cinderella,
Sleeping Beauty and more all have recycled footage in them.
We'll allow the little cheat - when you consider that all of these scenes are hand drawn and not computer generated it really is pure magic.
If it ain't broken, don't fix it.
