A Betty Boop Cartoon
Fleischer Studios (1932)
Betty Boop appears on stage in a vaudeville theatre. Her act consists of imitations of real-life singers, including Helen Kane, Fanny Brice and Maurice Chevalier. The cartoon audience enthusiastically cheers and applauds.
When the short was originally released, it contained a scene showing Betty singing Helen Kane’s song “That’s My Weakness Now.” Kane, who was involved in a lawsuit over Betty’s resemblance to her, complained, and the studios were forced to remove the scene from future prints.
Clips from this short were later reused in 1934’s Betty Boop’s Rise to Fame.
I remember reading about Betty Boop a while back. Kane had seen Esther Jones performing in a club where she sang in a baby voice and coined the, “Boop boop be doop” lyric. Nobody seems to know about Esther Jones, but she appears to have been the real origin of Betty Boop!
