Continuity: The young Marquis d'Apcher is wounded on his right arm during the fight with the beast. Later, it is his left arm that is bandaged.
Continuity: When Mani is raised above the crowd, his tattoos are on the wrong shoulder.
Revealing mistakes: In the "final" fighting scene by the ruins, the wire that makes one of the women "fly" is visible when she lands in the leaves.
Continuity: The young woman in the water pit goes from holding a nubby horned baby goat to holding a lamb (without nubs), then to holding a baby goat again.
Continuity: The body of the young woman which is used as bait for the wolf is that of the shepherdess (the lady with the goat), who isn't killed until about an hour later in the movie. (The shepherdess scene was originally shot to take place much earlier in the film and when it was switched to later, they just hoped no one would notice the body was identical.)
Revealing mistakes: The metal claw weapons wiggle when struck in some shots, revealing that rubber look-alikes have been substituted for those shots.
Continuity: When de Fronsac gets out of bed after the nightmare and walks to the window, while hearing the band, he lacks the scars on his chest. Both the bear and arrow scars.
Revealing mistakes: In the final battle scene, before Fronsac kills Jean François, when he murders one of the "wolf-women" we can clearly see that he strikes the ground and not the woman's body.
Revealing mistakes: When Grégoire is shown using pumpkins for target practice, the pumpkins shatter and splash an opaque orange fluid. Pumpkins do not contain such fluid inside them.
