This episode was banned for its depiction of war and its unflattering stereotypes of East Asians. It did occasionally pop up on Toon Disney, with its last re-airing taking place in December of 2002.
The episode's premise is loosely based on the 1933 James Hilton novel Lost Horizon, in which the survivors of a plane crash in the Tibetan mountains find a hidden utopia city called Shangri-La.
