This movie was originally filmed in 1982 and was entitled: "The Gammelgormium Incident." The resulting (somewhat disappointing) production caused the director to abandon filmmaking entirely and pursue a career in engineering. Decades later the director was in a position to try it again, this time the results were much better.
The movie was film in a building with a metal roof, which meant ever time it started raining live action filming had to stop (which occurs a lot in Washington State).
