'The Nutcracker' is a two-act ballet composed by Tchaikovsky, and premiered in 1982. Although the ballet itself was not a roaring success when it first opened, the music definitely was, and is one of Tchaikovsky's most famous works to this day, including the music for 'Sleeping Beauty' which was the reason Tchaikovsky was commissioned to compose for 'The Nutcracker' in the first place. While listening to several different movements of the ballet on a friend's ipod, I remembered where I had first heard the music: Disney's 'Fantasia'.
For anyone who doesn't know the 1940s film, 'Fantasia' is a production by Disney that incorporates the greatest classical works from various periods and sets them to suitable animations.

However, in my opinion, I believe it to be one of the most original animations out there, and demonstrates the power of creativity and interpretation.
