Goof: Blanche is an orangutan. Buffalo Bill says he stayed in Africa for 40 years before moving back to the United States. But orangutans come from Borneo and Samutra... Pongo: Pygmaeus (Borneoan Orangutan)
Pongo abelii (Sumatran Orangutan)
Therefore a very unlikely scenario for an orangutan being in Africa, more so in the 1880's! And why didn't they use a chimpanzee?
