When you release a movie that contains nudity - even animated nudity - you can usually rest assured that you're going to get a restricted certificate, and children won't be allowed to see it. Apparently, though, the rules don't apply to Disney.
For reasons that nobody has ever got to the bottom of, the harpies in 'Fantasia' are topless. There's no attempt to hide that fact - their breasts are completely exposed. Like we said before, 'Fantasia' is a very strange film.
