Crowning Moment of Heartwarming: On a meta sense, Thom Christopher recalls his experiences when making the film. The cast and crew knew it was campy and silly, but made the best of it and had a legitimately fun time while making it. Another story is how he spoke with the prop manager about using a parrying knife for his fight scenes and said prop manager forged the knife from scratch.
How weird is it that the magic Troxartas is using to hold the souls of the warriors he has defeated does nothing to stop those same warriors from plotting with Deathstalker to find the artifact that is trapping their souls to begin with?
Fridge Brilliance: The magic works on Literal Genie rules and doesn't stop the undead from taking other actions independently unless specifically told not to. i.e. Troxartas told them to bring Deathstalker back to his castle - he didn't specify that Deathstalker had to be dead first.
Also, why doesn't Deathstalker destroying the artifact cause the Warriors From Hell to just drop dead right there? They stay in the battle, fighting for the good guys.
