Fantasia (1940)

This combination of classical music and hand drawn animation produced perhaps the most beautiful film o all time. - JW

Disney animators set pictures to Western classical music as Leopold Stokowski conducts the Philadelphia Orchestra. "The Sorcerer's Apprentice" features Mickey Mouse as an aspiring magician who oversteps his limits. "The Rite of Spring" tells the story of evolution, from single-celled animals to the death of the dinosaurs. "Dance of the Hours" is a comic ballet performed by ostriches, hippos, elephants, and alligators. "Night on Bald Mountain" and "Ave Maria" set the forces of darkness and light against each other as a devilish revel is interrupted by the coming of a new day.

From IMDB:

This is an example of a cinematic milestone
I first remember hearing about this movie when I was very little, and ever since I first watched it on VHS, it has always been one of the many examples of my favorite movies of all time. This is so unique, because unlike a typical Disney movie, in this movie we do not hear any dialog from the characters, and all of the music is instrumental (except for "Ave Maria" at the end). The film is divided into eight sequences, each of them being introduced by a guy named Deems Taylor, who was a very well-known music critique.

The eight segments are as follows:

1.) "Tocatta & Fugue in D-minor" composed by Johanne Sebastian Bach. This segment consists of shots of the Philadelphia Orchestra and their conductor Leopold Stokowski with a lot of cool shadow and color effects during the first three minutes, then we see a lot of shapes and random objects that Taylor would suggest to us might pop into our brains when listening to the music.

2.) "The Nutcracker Suite" composed by Tchaikovsky. In this part of the movie, we listen to excerpts of the famous ballet suite, and we see various fairies, flowers, fish and other nature-related creatures.

3.) Everyone's favorite "The Sorcerer's Apprentice" starring Sorcerer Mickey and Yen Sid (the sorcerer whose name is "Disney" spelled backwards). This is also the only segment to be seen again in this film's sequel, "Fantasia/2000" 60 years later, and in it the apprentice brings to life a magical broomstick to try to fill a cauldron with water, and the spell goes wrong so the apprentice gets reprimanded. This is then followed by Mickey greeting conductor Stokowski.

4.) "Rite of Spring" composed by Igor Stravinsky. This segment takes place billions and billions of years ago with the coming of the dinosaurs, where we see the creation of Earth in the beginning of time, and are later introduced to all of the different dinosaurs including the tyrannosaurus rex, which become extinct in the end of the segment.

5.) "Intermission/Meet the Soundtrack". At this point in the film, Deems Taylor introduces this string thingamajigger called the "Soundtrack" that he asks to make a lot of sounds resembling various instrument sounds.

6.) "Pastoral Symphony No. 6" composed by Beethoven. This segment is about a day in the countryside, and in it we see a lot of Greek mythology creatures like unicorns, satyrs, centaurs and centaurettes, cupids, Bacchus, Zeus, Iris, Apollo and Diana.

7.) "Dance of the Hours". This is where we see dancing ostriches, alligators, elephants and hippos. Each part of the piece suggests different hours of the day, and it all ends with a triumphant finale where the dancing hippo takes center stage.

8.) A combination of two pieces that are utterly different in mood and tone. They are "Night on Bald Mountain" in which a bat villain named Chernabog.
