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.
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: Listen to them. Children of the night. What music they make.
Count Dracula: I am Dracula. I bid you welcome.
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: So he could seduce Mina slowly with his hypnotic eyes, Dr. Steward would have been in the way.
