The film is based on a Ukrainian folk tale.
All additional voices were performed by the crew members to save money. Director Eduard Nazarov performed as a narrator (uncredited).
Two sculptures of Wolf were put up in Russia. The first one, made of bronze, was put up in Tomsk in 2005 and the other one, made of steel, was put up in Angarsk in 2007. Both Wolves can pronounce some of Wolf's lines from the film.
At first, Wolf looked different but when he was voiced by Armen Dzhigarkhanyan, it turned out the drawn character didn't fit Dzhigarkhanyan's voice and he was re-drawn.
