5,000 Emperor Scorpions were used during production, using a quarter of the film's budget.
Filmed consecutively with Eve (1989) and Savannah (1989), using much of the same cast, crew and locations.
Hugh Ecklund's character, Dr. Edward Ludwig, is named after the director of the 1957 film "The Black Scorpion"
As a practical joke, Dominique Harris brought a live scorpion to the set of '"Savannah" (1989)', another film in which she was starring, which was shooting at the same location. No one noticed, and there are two scenes in "Savannah" where the scorpion is clearly visible on Dominique's lap.
