A majority of the sets in this movie had been used in previous films made by New World Pictures.
The music score was made up of re-edited cues from James Horner's scores for Battle Beyond the Stars (1980) and Humanoids from the Deep (1980). The construction was done by film editor R.J. Kizer.
The movie was originally going to be released alongside Star Wars: Episode VI - Return of the Jedi (1983). It ended up being released 2 months later.
