[Renfield is being seduced by Dracula's brides.]
Renfield: This is wrong. Do you hear me? Wrong. This is...WRONG ME! WRONG ME! WRONG MY BRAINS OUT!
Dr. Seward: Your master is gone forever, Mr. Renfield. You are your own man now.
Renfield: I am?
Dr. Seward: Yes. No one will ever control you again.
Renfield: You're right.
Dr. Seward: Good. Come, Renfield.
Renfield: Yes, Master.
Dracula: You are a very wise man, Van Helsing, for someone who has yet to live a single lifetime!
[Renfield sees the blond and brunette vampire women in his room, rubbing themselves on the table and bedpost.]
Renfield: My god, what are you doing to the furniture?
Van Helsing: And if she dies a victim of this unspeakable creature, she will become one herself!
Dr. Seward and Jonathan Harker: What?
Van Helsing: She will become one herself!
[Attempting to kill vampire Lucy.]
Van Helsing: Hit her again. How much blood can she have left?
[Looking at Vampire Lucy in her coffin.]
Jonathan Harker: Now she's dead.
Van Helsing: No.
Jonathan Harker: She's alive?
Van Helsing: No, she's Nosferatu.
Jonathan Harker: She's Italian?
Answer: A clip from Mutiny on the Bounty is used in the ship scene. I believe it's on deck before Renfield and Dracula are seen. The premature burial is the scene when Lucy's coffin is being carried on the moors.
