Audio problem: After the part where Johnny Depp finds his bookstore friend dead, he gets back in the cab. After driving for a while, he tells the cab driver to pull over to the phone booth. The cab driver says "No problem, sir" but you can see the cab driver's lips in the rear view mirror, and they never move.
Continuity mistake: As Corso leaves Quinta Fargas, he barely dodges a speeding car aiming to ram him. Clasping his canvas bag tightly, never dropping it, he presses his back against a large tree. As the camera cuts to a close-up, the bag is suddenly a yard away from him, on the ground.
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.Charles Austin Miller
Boris Balkan: Look around you, all of you, what do you see? A bunch of buffoons, in fancy dress. You think the prince of Darkness would actually deign to manifest himself before the likes of you? He never has and he never will. Never.
Question: Would the gas station still be called Shell and not the French word? Also, do they drive on the same side of car and street in France?
