The Film - Fantasia, dir. James Algar (by way of W. Disney)
The Set-Up - A mouse and a magic hat. Nuff said.
What I love about Fantasia is watching with the knowledge that I am seeing a truly seminal moment. Disney had already broken the animation game wide open with Snow White and the Seven Dwarfs, and now his animators took what they had already learned and went into hyperdrive. This film reached new heights in just about any area you care to name - Color, movement, music, plot. The bar was now raised.
