Filmed in 1983 but never officially released. Filmed mostly in Budapest, Hungary, the Hungarian government seized most of the production's equipment for non-payment of bills. Post-production was never completed. Cannon Films bought the film in 1987 and planned to complete post-production and release the film. But the company began having financial troubles in 1988 and the film was forgotten. The existence of this film was questioned until a workprint surfaced on the internet in 2007.
Nick Maley created an animatronic bear for the film but was not able to get it to work properly. A new bear created with special effects was going to be added to the film but post-production was never completed. In the leaked workprint, the animatronic bear appears only briefly in the final scenes. Earlier scenes in which the bear was featured are replaced with a blank screen.
The concert scenes were filmed after a performance by Nazareth. The crowd was unaware that the following act was not a real band and were being recorded for a film. It was the largest gathering in Hungary since the Hungarian Revolution of 1956.
