Edward S. Norton: That witness from the train, what was his name?
Barton Keyes: His name was Jackson. Probably still is.

Phyllis: Do you make your own breakfast, Mr Neff?
Walter Neff: Well, I squeeze a grapefruit now and again.

Phyllis: I think you're rotten.
Walter Neff: I think you're swell - so long as I'm not your husband.
Phyllis: Get out of here.
Walter Neff: You bet I'll get out of here, baby. I'll get out of here but quick.

Phyllis: I was just fixing some ice tea; would you like a glass?
Walter Neff: Yeah, unless you got a bottle of beer that's not working.

Phyllis: I'm a native Californian. Born right here in Los Angeles.
Walter Neff: They say all native Californians come from Iowa.

Phyllis: Mr. Neff, why don't you drop by tomorrow evening about eight-thirty. He'll be in then.
Walter Neff: Who?
Phyllis: My husband. You were anxious to talk to him weren't you?
Walter Neff: Yeah, I was, but I'm sort of getting over the idea, if you know what I mean.
Phyllis: There's a speed limit in this state, Mr. Neff. Forty-five miles an hour.
Walter Neff: How fast was I going, officer?
Phyllis: I'd say around ninety.
Walter Neff: Suppose you get down off your motorcycle and give me a ticket.
Phyllis: Suppose I let you off with a warning this time.
Walter Neff: Suppose it doesn't take.
Phyllis: Suppose I have to whack you over the knuckles.
Walter Neff: Suppose I bust out crying and put my head on your shoulder.
Phyllis: Suppose you try putting it on my husband's shoulder.
Walter Neff: That tears it.

Phyllis: Neff is the name, isn't it?
Walter Neff: Yeah. Two "F"s, like in Philadelphia, if you know the story.
Phyllis: What story?
Walter Neff: The Philadelphia Story.

Phyllis: We're both rotten.
Walter Neff: Only you're a little more rotten.

Barton Keyes: Eh? There it is, Walter. It's beginning to come apart at the seams already. Murder's never perfect. Always comes apart sooner or later, and when two people are involved it's usually sooner. Now we know the Dietrichson dame is in it *and* a somebody else. Pretty soon, we'll know who that somebody else is. He'll show. He's got to show. Sometime, somewhere, they've got to meet. Their emotions are all kicked up. Whether it's love or hate doesn't matter; they can't keep away from each other. They may think it's twice as safe because there's two of them,
Barton Keyes: [chuckles]
Barton Keyes: but it isn't twice as safe. It's ten times twice as dangerous. They've committed a *murder*! And it's not like taking a trolley ride together where they can get off at different stops. They're stuck with each other and they got to ride all the way to the end of the line and it's a one-way trip and the last stop is the cemetery. She put in her claim... I'm gonna throw it right back at her.
[Walter hands Keyes a light]
Barton Keyes: Let her sue us if she dares. I'll be ready for her *and* that somebody else. They'll be digging their own graves.

Barton Keyes: I picked you for the job, not because I think you're so darn smart, but because I thought you were a shade less dumb than the rest of the outfit. Guess I was wrong. You're not smarter, Walter... you're just a little taller.
