The film is based on the 70s anime series Ganba no Boken (1975).
There exists an alternate English dub to the film produced by SC Films International. The dub cast features Jack Merluzzi, Ryan Drees, Jeff Manning, Walter Roberts, Michael Rhys, Eric Kelso, Katie Adler, and Julia Yermakov. Unlike the US version this dub retains the original Japanese names and title. The only known availability this dub has is on the Swedish Blu-ray release.
