Which animated film is considered a milestone in the evolution of animation?

The choice of "Snow White and the Seven Dwarfs" as a milestone in the evolution of animation is correct due to its significant historical impact as the first-ever full-length animated feature film. Released in 1937 by Walt Disney, this film not only showcased the potential of animation as a storytelling medium but also set the standard for character development, voice acting, and musical score in animated films.

Snow White's success established animation as a major art form and laid the groundwork for the entire animation industry, leading to the creation of numerous classics that followed. By pushing technical boundaries, such as the use of the multiplane camera, the film demonstrated how animation could convey emotion and narrative in a manner that resonated deeply with audiences of all ages.

While films like "The Lion King," "Finding Nemo," and "Shrek" have also made their marks in animation, they came later and built upon the foundation that Snow White had created. Each of those films features advancements in animation and storytelling, but none hold the same pioneering status as Snow White, making it a true landmark in the history of cinema and animation.
