* OutlivedItsCreator: Yes. The Sequel. But this began with István Fekete having a son (also called István Fekete) who though that he absolutely must write sequels for his father's work (he owned the rights after his father's death anyway)... unfortunately he neither has [[ToughActToFollow the talent]] nor the [[ArtisticLicenseBiology understanding of biology]]. The one for ''Vuk'' got licensed and the rest is history.
* WhatCouldHaveBeen: The original makers actually intended to produce a sequel for this movie. A traditionally animated one that kept the original character designs (except fixing the HumanlikeFootAnatomy) and focused on the adventures of a white fox with no input from István Fekete junior.
* WriteWhatYouKnow: István Fekete (the older) was born in a village, had a degree in agriculture, and was an active hunter since childhood. [[ShownTheirWork Let's just say it shows]]. (For comparison István Fekete junior was/had neither and that shows too.)
