Even today it would be difficult to find an animated movie that was not influenced in some way by Walt Disney. He was the first person to successfully synchronize sound with video in “Steamboat Willie.” In Snow White, he was responsible for making the first feature length animated film. In The Three Cabelleros, he did the unthinkable, combining live action film with animation, repeating this technique in Mary Poppins, a much beloved and widely popular film. He also invented the multi-plane camera, which allows an animation to have several layers, giving it depth. Really, Walt Disney was responsible for most of the basic things we expect in animation today. Not only did he affect the technology of animation, but he also used his movies to convey and reinforce moral lessons. Disney put magic and emotion into animation, an art form that was once strictly comic.
