The password to activate the self-destruct device on the undersea platform is shown on the screen to be "Nostromo". Nostromo was also the name of the interstellar mining ship from the original Alien (1979) movie; a movie from which The Alien Within borrows heavily.
Shot in eighteen days.
Producer Roger Corman reused all of the underwater shots and effects he'd had made for "Lords of the Deep" in 1989.
