Dumbo is a 1941 American animated musical fantasy comedy-drama film produced by Walt Disney Productions and released by RKO Radio Pictures. The film is based upon the storyline written by Helen Aberson and Harold Pearl, and illustrated by Helen Durney for the prototype of a novelty toy ("Roll-a-Book").
The main character is Jumbo Jr., an elephant who is ridiculed for his oversized ears and mockingly nicknamed "Dumbo", but in fact he is capable of flying by using his ears as wings. Throughout most of the film, his only true friend, aside from his mother, is a mouse named Timothy – a relationship parodying the stereotypical animosity between mice and elephants.
Produced to recoup the financial losses of both Pinocchio and Fantasia, Dumbo was a deliberate pursuit of simplicity and economy.
