Steamboat Willie is a 1928 American animated short film directed by Walt Disney and Ub Iwerks. It was produced in black-and-white by Walt Disney Studios and was released by Columbia Pictures. The cartoon is considered the debut of Mickey Mouse and his girlfriend Minnie, although both the characters appeared several months earlier in a test screening of Plane Crazy. Steamboat Willie was the third of Mickey's films to be produced, but was the first to be distributed because Walt Disney had, having seen The Jazz Singer, committed himself to producing the first fully synchronized sound cartoon.
The film is especially notable for being the first Disney cartoon with synchronized sound, including character sounds and a musical score. Disney understood from early on that synchronized sound was the future of film. Steamboat Willie was the first cartoon to feature a fully post-produced soundtrack which distinguished it from earlier sound cartoons such as Inkwell Studios' Song Car-Tunes (1924–1927) and Van Beuren Studios' Dinner Time (1928). Steamboat Willie would become the most popular cartoon of its day.
Music for Steamboat Willie was arranged by Wilfred Jackson and Bert Lewis, and included the songs "Steamboat Bill," a composition popularized by baritone Arthur Collins during the 1910s, and "Turkey in the Straw" , a composition popularized within minstrelsy during the 19th century. The title of the film is a parody of the Buster Keaton film Steamboat Bill Jr. (1928), itself a reference to the song by Collins. Walt Disney performed all of the voices in the film, although there is little intelligible dialogue.
While the film has received some criticism, it has also received wide critical acclaim, not only for introducing one of the world's most popular cartoon characters, but for its technical innovation. In 1994 members of the animation field voted Steamboat Willie 13th in the book The 50 Greatest Cartoons, which listed the greatest cartoons of all time. In 1998 the film was selected for preservation in the United States' National Film Registry for being deemed "culturally, historically, or aesthetically significant."
