Factual error: In the scene where the cast find the guns in the tiny coffins, they mention that it is not possible to tell if they are loaded because the clips are welded. Being semi-automatic pistols, simply pulling back the slide & ejecting the first round would have easily determined whether live or blank rounds had been loaded.

Peter Graves: Dr. Richard Benjamin Vannacutt. He out-butchered Bundy, made Manson look meek.
Trivia: The darkness that emerges and begins to kill the guests was actually created when the animators took film of dancing naked women and mirrored the image over and over.
Question: Who exactly is the person that Melissa sees behind her before it attacks her?
Answer: Just a generic ghost/monster as it has no face.
Answer: The ghost that kills Melissa is the patient Vannacutt was dissecting. When Melissa initially sees them through her camera, what she's really seeing is the ghosts re-living their last moments.
