Other mistake: Covering the victims' bodies with layers of wax would make the figures look unnatural large. And the machine that secured the victims in seated position as it sprays then with layers of hot wax would mean the figures would have to stay in seated positions when completed.

Continuity mistake: Nick's shirt he gave to Carly is way too big on her when she first puts it on. In the next scene it fits like it's her own shirt.
Nick Jones: You're saying that that's a real person... underneath?
Trivia: The "wax" bed is made out of peanut butter, and melted wax for effects.
Question: What was the heinous metal contraption placed on Wade's head, prior to him being sprayed with hot wax, supposed to insinuate? The needle-like probes did not appear to puncture him. Was it simply for effect?
Answer: It is simply a contraption to keep Wade in place so he doesn't move and the wax can be applied. It's also used to keep the wax out of his eyes, ears, nose and mouth.
