Sinkin’ in the Bathtub is the very first Warner Bros. theatrical cartoon short as well as the very first of the Looney Tunes series. This cartoon was first theatrically released with the lost Warner Bros./Vitaphone Technicolor film The Song of the Flame.
The short was produced and directed by Hugh Harman and Rudolf Ising, with animation by a very young Friz Freleng. Leon Schlesinger was credited as an associate producer, and the title card also gave credit to the Western Electric apparatus used to create the film.
This short marked the theatrical debut of Bosko the “Talk-Ink Kid” whom Harman and Ising had created to show to Warner Brothers. Bosko became their first star character, surpassed only much later by Porky Pig and Daffy Duck. Notably, this is the only publicly released Bosko short to feature Bosko’s original blackface dialect; he would later adopt a more falsetto voice for later films. Also, this is the first publicly released non-Disney cartoon to have a pre-recorded soundtrack (in addition, “Bosko, the Talk-Ink Kid” had a pre-synched track.) [Wikipedia]
