Ruth: Who would want to haunt me?
Frederick Loren: I would say any self-respecting male ghost.

Annabelle Loren: And you call this a party?
Frederick Loren: Could be.

Annabelle Loren: Dr. Trent, don't you approve of our little party favors?
Dr. David Trent: Suppose Nora had a gun when she was alone in the cellar with the blind woman?
Ruth: Oh I don't think anyone else is going to walk around in total darkness.
Annabelle Loren: Oh I'm sure we're not going to go running around the house shooting each other, aren't you?
Dr. David Trent: Who knows? Fear can make people do amazing things.

Watson Pritchard: [about the guns they're given] These are no good against the dead, only the living.

Watson Pritchard: [looking at blood stain on ceiling] See that stain? Blood. A young girl was killed here... and whatever got her wasn't human.

Watson Pritchard: [opening lines] The ghosts are moving tonight, restless... hungry. May I introduce myself? I'm Watson Pritchard. In just a moment I'll show you the only really haunted house in the world. Since it was built a century ago, seven people including my brother have been murdered in it, since then, I've owned the house. I only spent one night then and when they found me in the morning, I... I was almost dead.

Watson Pritchard: [shows everyone a knife] This is what she used on my brother and her sister, hacked them to pieces. We found parts of their bodies all over the house, in places you wouldn't think. A funny thing is the heads have never been found, hands and feet and things like that, but no heads.
Dr. David Trent: The wife, probably in a fit of rage, threatened her husband with the knife, and then, carried away by hysteria, took a swing at him and simply went on from there.
Lance Schroeder: [laughing] She certainly went on, how many people did she kill, Mr. Pritchard?
Watson Pritchard: Only two, her husband and her sister, nobody else was here.
Lance Schroeder: So there are two loose heads just floating around here someplace?
Watson Pritchard: You can hear them at night, they whisper to each other, and then cry.

Watson Pritchard: Only the ghosts in this house are glad we're here.

Watson Pritchard: There's been a murder almost everyplace in this house!

Watson Pritchard: These guns are no good against the dead. Only the living.
