If I remember correctly, Galaxy of Terror (along with a couple of other movies released in close time proximity) also cannibalized some visual FX from Roger Corman's "Battle Beyond the Stars".
Movies that I know cannibalized BBtS:
Space Raiders (1984-85)
Murder In Space (Showtime original sci-fi murder mystery)
What's worse, there's actually a movie out there that cannibalized visual effects from the original Battlestar Galactica. I say worse because that movie ripped off VFX from a TV series.
