* EarWorm:
--->"When the swallows come back to Capistrano,
--->That's when I'll come back to you."
* EvilIsSexy: Livia. Oh, Livia. Amusingly, Pendragon seems thoroughly immune to her charms.
* IdiotPlot: Quintis's temporal tomfoolery aside, most of the plot is moved by the fact that Pendragon is dumber than a sack of concussed doorknobs.
* {{Narm}}: '''STAY!'''
* SoBadItsGood: Everyone involved is clearly trying. The surprisingly decent-looking sets also deserve special mention, considering the whole film was made in ''six days'' in a converted supermarket.
* {{Squick}}: Satan's apparently off-centre Adam's apple.
* ValuesDissonance: Pendragon tells Helene that "[She] couldn't fool a child in its cradle" when she claims to have deceived Meg Maud. It's meant as a compliment to her guilelessness and purity of character, but today it sounds like a straight-up insult.
* VindicatedByCable: Despite the meager budget, ''The Undead'' is one of the more thought-provoking B-movies of its kind.
