All movies are animated, in that a film strip is composed of still images that, when moved fast enough before a beam of light, create the illusion of movement. But a film with flesh-and-blood actors is limited by the human body. A sequence of still images of Brad Pitt's arm swinging from right to left is only possible if you get a camera on Brad Pitt as he moves his arm from right to left.

Gather a room of animators, though, and the results don't have to be tethered to any reality. Before CGI unlocked new wonders and sights, cartoons were the best ways to create the unreal. Even in 2013, a great animated movie does work that no actor/CGI mash-up can accomplish. Still, for a animated flick to be truly great, it needs to have the magic of story, and that means humanity.

Drawing on films from around the world, these are the 50 Best Animated Movies of All Time.
