Dumbo is a 1941 animate feature film produced by Walt Disney and first released on October 23, 1941 by RKO Radio Pictures. The fourth film in the Disney animated features canon, Dumbo is based upon a child's book of the same name by Helen Aberson and illustrated by Harold Perl. The main character is Jumbo Jr., a semi-anthropomorphic elephant who is cruelly nicknamed Dumbo. He is ridiculed for his big ears, but in fact he is capable of flying by using them as wings. Throughout some of the film, his only true friend aside from his mother is the mouse Timothy, parodying the stereotypical animosity between mice and elephants.
