I saw this film in 1985 at "Free Kids Matinee Movie" day during Crazy Days in Ortonville, Minnesota. It only showed films on the weekends, Friday through Sunday, and the theater closed every winter, because the owners couldn't afford to heat it. Its main supporting beam broke during the winter of 1988, and they tore it down a couple years later. The last film they ever showed: Crocodile Dundee II.
"The film was not produced by Hanna-Barbera, the creators of the Smurfs television series, but by Brussels' Belvision Studios. The voice talent from that show was not present in the English version either; instead, the work was handled by a non-union crew whose members had previously appeared in anime dubs for U.S. television."
