Trivia: Kevin Smith once happened upon a demonstration against this movie by a group of Catholics. Since nobody recognized him, he simply joined in.
Trivia: Christopher Walken doesn't speak a single word in the entire course of the movie.
Trivia: Probably the most impressive visual effect in this film is when Corso consults the twin brothers Pablo and Pedro Ceniza (rare book experts). Both Ceniza twins were played by actor José López Rodero in the subtle and entirely convincing digital effect sequence. The only flaw was that the elderly twins had identical facial wrinkles, which never happens with real-life twins. Beyond that, José López Rodero additionally played the two nameless workmen that Corso encounters at the end of the film, meaning that Rodero played four digital-effect roles in this movie.
Trivia: After Frankie tears up the apartment, possessed by the priest, she goes to the bed and levitates in a cruciform position. During this scene, there is a quick, sweeping shot of the wall and, if you watch it in slow motion, you can see a wall of boxes of Ritz crackers. This is either an obvious endorsement or some kind of inside joke.
Trivia: The story of this film is basically a retelling of the story of Beowulf and Grendel. Buliwyf is Beowulf, the Wendol are Grendel, King Hrothgar is of course himself. Ahmed Ibn Fahalan was added to lend the story historical credence as Ahmen Ibn Fahalan really did travel north from Baghdad and encountered Viking men.
Trivia: The Mystery Men were originally a supporting crew for an underground superhero called The Flaming Carrot. The only original members of the Mystery Men to come from the comic book are the Shoveler, and Mr. Furious.
