Steamboat Willie premieres in movie theaters
When Steamboat Willie debuted, it was the third cartoon to feature an early rendition of Mickey Mouse. In this seven-minute animated short directed by Walt Disney, Mickey is steering a steamboat, whistling a happy tune, sassing Captain Pegleg Pete, and trying to impress Minnie Mouse. Most of the short features Mickey creating an impromptu orchestra with a bunch of animals on the boat.
For its significance as a milestone in animation, Steamboat Willie is one of 25 films added to the National Film Registry in 1998.
