Dracula (1992)

Continuity mistake: When the brides of Dracula come out topless to suck Jonathan's blood, Dracula breaks in, furious, and the brides are suddenly fully clothed. (00:32:45 - 00:34:25)

Revealing mistake: When Arthur is guarding Lucy, just before he sees Dracula, a female voice can be heard saying "Now", cuing him to turn his head. (01:16:20)

Continuity mistake: During the crypt scene, when Lucy's body is interred, the shots of her in the glass coffin and later rising out of it, show dramatic difference in the depth of the coffin. (01:24:55 - 01:27:05)

Revealing mistake: In the crypt scene, Van Helsing, as you can see, cuts off Lucy's head. But when the head pops off, you can see that where there should be blood, guts, flesh, etc., there is only some white blankness. (01:27:45)

Continuity mistake: When Van Helsing breaks the news to Quincey after reading the "Vampyr" book, as he says, "Yes, we may still save her precious soul", he's gripping Quincey's coat, and Quincey's left arm is down, but in the previous shot, Van Helsing's arms were down by his side, and Quincey was holding onto the hat on his head. His other arm changes position as well. (01:14:15)

Revealing mistake: When Dracula first bites Lucy, the wounds can be seen on her neck before the actual bite. (00:40:35)

Continuity mistake: After Dracula opens a vein in his chest, his hair alternates between being over/behind his shoulder, depending on the camera angle. (01:36:15)

Continuity mistake: When Prince Vlad tilts the baptismal font, the stains of Elisabeta's blood on the floor changes position between the overhead shot and the close-up, easily seen from the cracks in the floor. (00:04:10)

Continuity mistake: When Keanu Reeves is being seduced by Dracula's brides, Monica Bellucci rips open his shirt, but in the previous shots, his shirt is already open. (00:31:45)

Continuity mistake: When Dracula stamps the paper in the castle, in the wideshot, the wax seal is several centimetres away from his signature, but in the close-up, it is right next to his name. Also, his signature differs slightly between the two shots. (00:15:05)

Visible crew/equipment: In the scene where Lucy is done in by Dracula in wolf form, as she dies, blood is exploded into the room by "supernatural" forces. If you look in the torrent of blood, you will see the gas, I assume carbon dioxide, from the special effect cannon appear and evaporate. (01:21:00)

Revealing mistake: During the battle scene at the beginning of the film, you can tell that the group of soldiers in the background are just animatronics because their bodies remain stationary while their arms move in a clockwork repetitive manner.

Phaneron

Factual error: At the beginning of the movie, it was stated that Constantinople was captured by the Turks in 1462. The Turks actually captured it in 1453.

Revealing mistake: During Lucy's funeral scene, as the camera pans through the shot, you can see Lucy breathing when she's supposed to be dead. Very obvious on a big screen, not as much on a small screen.

Revealing mistake: When Harker is in the train, the outside shot shows a blatant model train, with empty carriages, plus no people and no curtains, as opposed to the inside shots.

Sacha

Continuity mistake: When Mina drops the book while talking to Lucy, both reach down to pick it up, and we see one of Lucy's hands holding the book on the floor. In the next shot, both her hands are at her waist. (00:19:10)

Continuity mistake: When Arthur sits by Lucy's bed while watching over her, as Dracula appears outside the window, there's a quick shot of the bedroom from outside, and Arthur is nowhere to be seen. In the next shot inside the room, he sitting by the bed again. (01:16:15)

Continuity mistake: When Dr. Seward is talking to Renfield, after Renfield says, "I need lives for the master", he puts his right hand over his mouth, but in the next shot, he's holding his left hand over his mouth. (00:24:30)

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)

Continuity mistake: When Elisabeta is lying dead in the chapel, her neck is showing, but after Dracula drinks blood from the chalice, her collar is suddenly reaching her chin. (00:05:00)
