Originally entitled (and filmed as) "Deadly Spawn 2: The Metamorphosis", intended to be a sequel to The Deadly Spawn (1983).
Production started in 1987, but due to the abundant stop-motion creations and special effects, production took years longer than planned, and after several lawsuits involved with the distributors, Trimark Pictures was given distribution rights. The film was released in 1991 to film festivals, and shortly after onto video, though it had an early release on VHS in Germany in November of 1990.
