The prayer the gargoyle queen offers up at the altar is part of a well-known Catholic prayer to St. Michael the archangel, the patron of the gargoyles.

This film acknowledges Frankenstein's Monster as "Adam" making it one of the very few screen adaptations to call him this name.

In the graveyard, after Adam has been saved from the demons by the gargoyles, but is unconscious, the female gargoyle exclaims 'it's alive, it's alive', just as Doctor Henry Frankenstein says in the original Frankenstein (1931) movie.

The Gargoyle Queen, Leonore, notes that the Frankenstein's creation was never given a name (and implies that he never took a name for himself).

There are three instances of "Adam" in the novel, all by the creation, all in third-party reference: "Remember that I am thy creature; I ought to be thy Adam, but I am rather the fallen angel..." (Chapter 10) "Like Adam, I was apparently united by no link to any other being in existence..." (Chapter 15) "I remembered Adam's supplication to his Creator. But where was mine?" (Chapter 15)

There is an alleged quote by Mary Shelley that 'if the creature had a name, it would be Adam.' Not only is this not from the novel but from an interview, but a clear hypothetical - 'if... would...' - and acknowledgment by the author that the creation has no name.

According to some reports, there was a lost scene in the original Universal Pictures' Frankenstein (1931) movie referring to Boris Karloff's monster as Adam. In the follow up Bride of Frankenstein (1935) it was stated that the monster's name was Frankenstein, which became the rule for that series of films.

Aaron Eckhart stated in an interview that during filming of one of the Kali stick fight scenes, he thought he broke his neck when he was hit with a powerful blow on the back of his neck during shooting. "I went down to the ground like a sack of potatoes."
