Trivia: When Mina meets Dracula on the street, after she first rebuffs him, she walks past a sandwich board advertising a play with Henry Irving at the Lyceum Theatre. For many years, Bram Stoker worked as the business manager of the Lyceum Theatre, which was run by Irving. The famous stage actor is widely believed to be one of Stoker's inspirations for Count Dracula. (00:46:30)
Trivia: The disclaimer, "Neither the name Zorin nor any other name or character in this film is meant to portray a real company or actual person" was added after the producers discovered a real company known as Zoran Ladicorbic Ltd, whose industry was fashion design. This is the first Bond film to begin with a disclaimer.
Trivia: When composer Éric Serra showed Inva Mula, the Albanian soprano who was going to sing the Diva Dance, the sheet music for that part, apparently she laughed and said that it was impossible for the human voice to switch from high to low notes that quickly. She got her way: The part that ended up in the film is not a single piece of audio, rather it's several pieces stitched meticulously together.
Trivia: The Noordermarkt scene in Amsterdam was not really shot there. In fact it wasn't shot in the Netherlands at all. The Noordermarkt in the film looks nothing like the real Noordermarkt, and more like an Asian or Indian market. The noise of people talking in the background does not resemble anything close to Dutch. The cars in the scene are rarely seen in the Netherland because they are too outdated to be seen frequently, especially all together. At timecode 42:30 you can see a police car with "POLICE" written on the side of it. However, in real life, Dutch police cars do not use the English word for police. "Politie" would have been the correct word, but even then the police car would not be convincing, as official police cars look entirely different. Finally, the firetruck appearing later in the scene is not a type used in the Netherlands, but appears to be an American Pierce Lance truck with Dutch fire engine stickers on it. Dutch firetrucks are usually of European make: DAF, MAN or Mercedes. (00:41:50 - 00:43:30)
Trivia: In the scene where Regan's mother is supernaturally blasted away from the bedside, she is being yanked by the crew by a length of rope. After dozens of takes director William Friedkin was still unhappy with the look of the shot and ordered the crew to haul her more fiercely. The scream in the shot that made the cut was of genuine pain and required no dubbing for effect.
Trivia: Because everything was shot against a green screen, some bits of colour proved difficult. Yellow Bastard especially was hard, as yellow bleeds into the green screen and can't be separated cleanly. To get around this, Robert Rodriguez painted him blue, then turned him yellow in post production.
