Maid: He's crazy.
Martin: They're all crazy. They're all crazy except you and me. Sometimes I have my doubts about you.
Maid: Yes.
Count Dracula: Listen to them. Children of the night. What music they make.
Count Dracula: I am Dracula. I bid you welcome.
Renfield: No, no, master. I wasn't going to say anything, I told them nothing. I am loyal to you master.
Count Dracula: The spider spinning his web for the unwary fly... The blood is the life, Mr. Renfield.
Van Helsing: Gentlemen, we are dealing with the undead.
Scholar: Nosferatu.
Van Helsing: Yes, Nosferatu.
Van Helsing: You'll die in torment if you die with innocent blood on your soul.
Renfield: God will not damn a poor lunatic's soul. He knows that the powers of evil are too great for those with weak minds.
John Harker: My, what a big bat.
Van Helsing: What have you to do with Dracula?
Renfield: Dracula?.. I never even heard the name before.
Doctor Seward: But, Professor Van Helsing, modern medical science does not admit of such a creature! The vampire is a pure myth, superstition.
Van Helsing: I may be able to bring you proof that the superstition of yesterday can become the scientific reality of today.
Count Dracula: This is very old wine. I hope you will like it.
Renfield: Aren't you drinking?
Count Dracula: I never drink... wine.
Renfield: I'm loyal to you Master, I 'm your slave, I didn't betray you! Oh no, don't! Don't kill me! Let me live, please! Punish me - torture me - but let me live! I can't die with all those lives on my conscience, all that blood on my hands.
Renfield: Rats. Rats. Rats! Thousands! Millions of them! All red blood! All these will I give you if you will obey me.
Count Dracula: For one who has not lived even a single lifetime, you're a wise man, Van Helsing.
Count Dracula: To die, to be really dead, that must be glorious.
Mina Seward: Why, Count Dracula.
Count Dracula: There are far worse things awaiting man than death.
Answer: Pretty sure this qualifies as a mistake, just like the llamas in Troy. Armadillos only live in the Americas. Later on, they have opossums too! So the story about not wanting to show rats could very well be true. Nevetheless, if this isn't a mistake, I don't know what is.
