Renfield: [overhearing Van Helsing discussing vampires] Isn't this a strange conversation, for people who aren't crazy?

Renfield: He came and stood below my window in the moonlight. And he promised me things, not in words, but by doing them.
Van Helsing: Doing them?
Renfield: By making them happen. A red mist spread over the lawn, coming on like a flame of fire! And then he parted it, and I could see that there were thousands of rats, with their eyes blazing red,l ike his, only smaller. Then he held up his hand, and they all stopped, and I thought he seemed to be saying: "Rats! Rats! Rats! Thousands! Millions of them! All red-blood! All these will I give you! If you will obey me!"
Van Helsing: What did he want you to do?
Renfield: That which has already been done!
[giggles sinisterly]

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: I'm loyal to you, Master, I am 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!
[Dracula picks up Renfield with his bony hands and in a few seconds, Renfield dies]

Renfield: No, no, master. I wasn't going to say anything, I told them nothing. I am loyal to you master.

Renfield: Rats. Rats. Rats! Thousands! Millions of them! All red blood! All these will I give you if you will obey me.

Renfield: You know too much to live, Van Helsing!

Van Helsing: What have you to do with Dracula?
Renfield: DRACULA?... I never even heard the name before

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.

Mina Seward: [doing an impression of Dracula] It reminds me of the broken battlements of my own castle in Transylvania.
[chuckles]
Mina Seward: Oh, Lucy, you're so romantic!
Lucy Weston: Laugh all you like. I think he's fascinating.
Mina Seward: Oh, I suppose he's all right. But give me someone a little more normal.
Lucy Weston: Like John?
Mina Seward: Yes, dear, like John.
Lucy Weston: [dreamily] Castle... Dracula... Transylvania!
Mina Seward: Well, Countess! I'll leave you to your count and his ruined abbey!
[both giggle]
Mina Seward: Good night, Lucy.
Lucy Weston: Good night, dear.
