Continuity mistake: When the great doors to Dracula's castle open, an ornate table with a statuette and two large candle holders is standing inside the castle. When Dracula's shadow appears, the statuette is still there, but the candle holders are gone. (00:12:35)
Continuity mistake: After Dracula pours wine for Jonathan, he sets down the carafe at the edge of the table, about a meter away on Dracula's left. In the next shot, it has moved much closer to him and is sitting on Dracula's right. In the wide shot where Dracula draws his sword, the carafe is back at the edge of the table. (00:13:30)
Continuity mistake: When Jonathan is dining in Dracula's castle, throughout the scene, his wine goblet keeps turning around on the table between shots: This can easily be seen from the two handles on the side, which keep pointing in different directions throughout the scene. (00:13:30)
Continuity mistake: When Jonathan is dining in the castle, as Dracula says "That relationship was not entirely successful", Jonathan's knife is pointing upward and there is nothing on his fork. In the next shot, his knife is pointing downward and there's a piece of food on his fork. The food stays on the fork during the next few shots, until Dracula says "It is no laughing matter", and the fork is suddenly empty again. (00:13:55)
Continuity mistake: As Dracula pours Jonathan wine in the castle, the arm-shaped, wall mounted torch on Jonathan's right is lit. A few shots later, as Dracula remarks, "That relationship was not entirely successful", the torch is unlit, but in the following wide shot where he draws the sword, the torch is burning again. In the shot where an angry Dracula says, "We Draculs have a right to be proud!", the torch is once again unlit. (00:14:15)
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)
Character mistake: When Jonathan is closing the transactions in Dracula's castle, there is a close-up of Renfield's card, which says "R. N. Reinfeild." However, the end titles spell the character's name as "R. M. Renfield", like in the novel, and Dr. Seward also refers to the character by this name in the first scene where he is recording his diary on the phonograph cylinder, just like he does in the book. (00:16:30 - 00:23:20)
Revealing mistake: When Jonathan closes the transactions in Dracula's castle, as Dracula's shadow is shown trying to strangle him, you can see Gary Oldman's real shadow on the right-hand side of the screen, standing in front of the shadow of Keanu Reeves. Also, in the final shot of the scene, as Dracula turns around and walks away, Dracula's shadow appears directly behind Jonathan, but Gary Oldman's own shadow can be seen on the right-hand side of the screen, moving in accord with the actor as he leaves the room. (00:17:26)
Continuity mistake: After Mina discovers the "Arabian Nights" book while she's typing, a chair behind her moves closer to the desk between the wideshot of her from behind, and when Lucy walks over to her. (00:18:15)
Continuity mistake: When Lucy sits down with Mina when Mina is typing, the folds in the curtain on the left change after they open the book. (00:19:10)
Continuity mistake: When Mina drops the Arabian Nights while talking to Lucy, both reach down to pick it up, and we see one of Lucy's hands touching the book on the floor. In the next shot, both her hands are at her waist. (00:19:10)
Continuity mistake: When Mina and Lucy are looking at the pictures in "Arabian Nights", as they open the book, both of Mina's hands are holding the book, but in the next shot, her right hand is up by her mouth. (00:19:20)
Continuity mistake: When Mina and Lucy are looking at erotic illustrations in the Arabian Nights book, in the wide shots of the girls holding the book, Mina's nails are cut short, but in the close-ups of her hands on the book, her nails are longer. (00:19:21)
Continuity mistake: At Lucy's dinner party, as Lucy is sitting on the couch with Jack Seward, Quincey Morris is holding his hat in his hands. When Lucy gets up from the couch to greet Arthur Holmwood, he is still holding it, but when the scene cuts back to Jack and Quincey a few seconds later, Jack gets a funny look on his face and then magically pulls Quincey's crumpled hat out from under his butt. (00:22:25)
Continuity mistake: When Dr. Seward first talks to Renfield, as Renfield inspects the spider, he is sitting in a corner and his hands are up as he dangles the spiderweb, but in the next shot, he's sitting right under the window and his hands are down. (00:24:50)
Continuity mistake: When Renfield blurts out to Dr. Seward "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. (00:25:30)
Other mistake: When Dr. Seward first goes to see Renfield, he gets bitten on the right side of his neck, but then grabs the left side as if in pain. (00:26:00)
Continuity mistake: When Jonathan is shaving, in the first shot, the mirror he is using is quite small and has a thin wooden frame. When Dracula grabs his shoulder, the mirror is much bigger and has a thicker frame. In the next shot, where Jonathan abruptly turns around, the smaller mirror is back. (00:26:10)
Revealing mistake: When Jonathan is shaving, there is a close-up of the back of his head, where Keanu Reeves and his body double are unsynchronized: As Keanu's reflection shows him beginning to lower his hand with the razor, the hand of the body double standing in front of the mirror is still up by his neck, before the body double lowers the razor a split-second later. (00:26:20)
Revealing mistake: Dracula has no reflection, as seen when Jonathan is shaving, and when Dracula buys the newspaper in London. But when he assists Jonathan with the shaving, every time he dips the blade into the water bowl, his red robe can be seen reflected in the bowl. (00:26:40)
Answer: It's unlikely they were falling in love with Harker: they are sadistic, baby-eating monsters who regarded Harker as food and a temporary plaything. As for them sleeping in the open, the local populace dreads and avoids Dracula's castle, so there's hardly any fear of intruders. Van Helsing did enter and kill them, but they reckoned, mistakenly, that he too would be too afraid to do so, especially after their horse-mauling escapades the previous night.
