Hugh Harman, Rudolf Ising & Friz Freleng (1929)
Sinkin’ in the Bathtub is the first Warner Bros. theatrical cartoon short as well as the very first of the Looney Tunes series. The title is a pun on the 1929 song Singin’ in the Bathtub.
The short was produced, directed, supervised and co-animated by Harman and Ising, with animation by a very young Friz Freleng and his friends. 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.
