Barnacle Bill (1930)

Barnacle Bill is a 1930 Fleischer Studios animated short film. It is part of the Talkartoons series, and featured Betty Boop (here called "Nancy Lee") and Bimbo (as "Barnacle Bill").
Like many early Fleischer Studios films, this film was inspired by a popular song, a version of "Barnacle Bill" written in 1928 by Frank Luther & Carson Robison and performed by Hoagy Carmichael. It has nothing to do with William Bernard, the sailor and California Gold Rush character known as "Barnacle Bill". Ironically, Fleischer Studios also produced a Popeye cartoon, Beware of Barnacle Bill in 1935, using the same song as aforementioned, almost 5 years after Betty Boop cartoon Barnacle Bill was released, with Bluto as Barnacle Bill the Sailor portraying the character after Bimbo.
In this cartoon, Betty Boop still retains some of the canine physical characteristics that she had in her first screen appearance, Dizzy Dishes.
