Box Office Bomb: Budget, $27 million (not counting marketing costs), $50 million (counting them). Box office, $16,519,460. In New York City, for instance, the film opened and closed on the same day in many theaters; even in 1983, that was rare for a film.
Creator Killer: This is one of multiple projects at the time that ended the career of writer Stanford Sherman.
The Danza: Almost. Lyssa is played by Lysette Anthony.
DVD Commentary: The commentary track consists mostly of the crew making excuses about the special effects and the cast name dropping famous people they've worked with in other films.
Executive Meddling: Frank Price, then-president of Columbia Pictures, determined that an unknown American actress would help stateside ticket sales better than an unknown English actress. Price met with Lysette Anthony and told her that all of her dialogue had been dubbed by Lindsay Crouse.
Fountain of Expies: The Glaive, a strange throwing weapon that resembles a large shuriken with retractable blades. While the name was derived from a European polearm, almost anyone that uses it anymore is usually geared towards this film's depiction of it. From Warcraft to Bloons Tower Defense.
Hey, It's That Sound!: The dub for the death screams of the Slayers was taken from the Mayar shrieks in At the Earth's Core.
Star-Derailing Role: The film killed Ken Marshall's movie career before it could even get started — fortunately, he found a recurring role in Star Trek: Deep Space Nine as Michael Eddington.
What Could Have Been: In the original screenplay, Colwyn saves Ynyr from the spider in the Widow of the Web's cave by killing it with the Glaive. But, it was cut from the movie.
