Factual error: At the cinematograph, Mina says to Dracula, "How can you call this science? Do you think Madame Curie would invite such comparisons? Really!" The movie takes place in year 1897, but Marie Curie's works weren't published until 1898. (00:49:30)
Factual error: When Virginia Madsen's character sees Candyman in the mental hospital, a male nurse calls for the injection of 1000 milliliters of sedative to calm her down. 1000 milliliters is equal to 1 liter, which certainly could not be injected, let alone as fast as it was.
Suggested correction: The nurse said 1000mg, which is true and accurate wording for medication.
First off, he actually said "bring me a thousand mills." Second, 1 gram equals 1 milliliter, one is liquid and one is solid.
Factual error: As the Thug Zombie is on top of the lawnmower and is getting hacked to bits, his body parts don't fly off. His arms would've gone everywhere when the blade reached his shoulders, and the same goes for his head. (01:29:15)
Factual error: The glass shattering and falling in the greenhouse would have been unlikely to kill Marlene, let alone even cause that much damage to her, as the glass would have very little to no time to gain more force, falling at that low of a height. And if Marlene were to be killed, she would have probably bled out over time, as opposed to almost instantly dying as the film implies.
Factual error: The forensics report says that Leptospira interrogans is the virus which causes Weil's disease. Leptospira is actually a bacterium. (00:52:20)
Factual error: When Gus brings Renee's body over to Jeff, notice her feet. Shes been dead for a while yet her skin is normal color as if she was alive.
Factual error: Ron Pearlman plays a state police captain named "Captain Soames". On his uniform he has both captain's bars on his shirt collar and sergeant's stripes on his upper shirt sleeves. He would not hold both ranks and would not keep the sergeant's stripes on if he had been promoted to captain. He also would have gone through the rank of lieutenant (one bar) prior to becoming a captain, so he would have had plenty of time to take the stripes off his uniform.
Factual error: After coming out of the pit, Ash gets three shots out of a double barrel shotgun. There was a sound of cocking when the shotgun has to be cracked open to re-load.
