The set dresser on this film was Bill Paxton, before he took to acting. He was employed by the film's Art Director, and future frequent collaborator, James Cameron.

Taaffe O'Connell was nearly crushed by the one-ton giant worm during the filming of the notorious rape scene.

Future director James Cameron worked as Art Director on this movie, but got a big career break when he noted that the director and camera crew didn't produce enough shots. He requested to be Second Unit Director as well, so that he could film additional shots. His request was honored, and one of his suggestions was adding a scene involving a severed arm covered with squirming maggots. Cameron used real maggots, but because they didn't move by themselves, he invented a set-up by hooking a power drill line to the arm and hiding the cords inside the set. One of his co-workers would then plug the wire into an electrical outlet, letting the maggots wriggle on cue. On the day that the effect was shot, two of the future producers of Piranha II: The Spawning (1982) were on set. They were so impressed by Cameron's ingenuity that they immediately told him they had big plans for his future, and signed him on for his first directorial deal when production on GoT was over.

The crew's suits were modified (different patches, tags, etc.) suits from Battlestar Galactica (1978) that the producers picked up for little money after the series was cancelled.

According to Producer Roger Corman, the film was budgeted at approximately seven hundred thousand dollars.
