Steamboat Willie

Steamboat Willie is a 1928 American animated short film directed by Walt Disney and Ub Iwerks. It was produced in black-and-white by Disney Cartoons and was released by Pat Powers' Celebrity Productions. The cartoon is considered the official debut of Mickey Mouse and Minnie Mouse, although both appeared months earlier in a test screening of Plane Crazy and the then unreleased The Gallopin' Gaucho. Steamboat Willie is the third film in the Mickey Mouse series to have been produced, but it is the first to have been officially distributed, because Disney had seen The Jazz Singer (1927) and became determined to produce one of the first fully synchronized sound cartoons.
