Other mistake: Even when not referring to his own emotions, The Collector can't say the word "love" when he is trying to seduce Jeryline at the end. He tries very hard to say it, but is simply incapable of using the word. Earlier, when The Collector was tempting Cordelia, he used the word several times without issue.Phixius
Other mistake: In the scene where they are 1st landing at Bangor it is known that there is no electricity at the airport. If you look closely during the landing you will see that the runway lights are on. (00:50:40)
Other mistake: When they are trying to figure out who the vampire is and they hold a ball and then they pull down a curtain and reveal a mirror it is obvious in the reflection that Mina has no partner and when they do their "finale" when Dracula is lifting her up it is obvious Mina has some other support that will continue to turn her after she is shown in the mirror while the vampire has no reflection.
Other mistake: In the beginning of the film when you're introduced to the younger, humanoid Sil in the laboratory, an extreme close-up of her eyes and face clearly reveals the young actor's contact lenses.
Other mistake: At the club, Sid likes the blue suit and takes it. But he is still wearing the suit he came in when Denzel's character shows up and is not carrying the blue suit as he leaves. If he somehow had it concealed on him it would have been shot up when he was thoroughly shoot. Yet when we next see Sid he is wearing the blue suit and there is not a mark on it.Frov
Other mistake: When Durant and his men chase Lauri out on the streets, they are waving around their guns and causing great commotion and panic amongst bystanders. However, in certain wide shots, you can see some of the extras are standing still, and not reacting to the chaos as they were in previous shots.
