Strangers on a Train (1951)
Guy Haines: I may be old-fashioned, but I thought murder was against the law.
Senator Morton: Poor unfortunate girl.
Barbara Morton: She was a tramp.
Senator Morton: She was a human being. Let me remind you that even the most unworthy of us has a right to life and the pursuit of happiness.
Barbara Morton: From what I hear she pursued it in all directions.
Bruno: My theory is that everyone is a potential murderer.
Barbara Morton: I still think it would be wonderful to have a man love you so much he'd kill for you.
Bruno Anthony: Don't worry, I'm not going to shoot you, Mr. Haines. It might disturb Mother.
Barbara Morton: Oh, Daddy doesn't mind a little scandal. He's a senator.
Senator Morton: You had no trouble, of course, with the police once they verified your alibi?
Guy Haines: When an alibi is full of bourbon, sir, it can't stand up.
Senator Morton: I'll have him called up immediately.
Barbara Morton: Obstructing the wheels of justice, Daddy?
Guy Haines: Doesn't that bloodhound ever relax? He sticks so close he's beginning to grow on me - like a fungus.
Bruno Anthony: When's the wedding?
Guy Haines: The what?
Bruno Anthony: The wedding. It's in the papers.
Guy Haines: Well, it shouldn't be. Not unless they legalized bigamy overnight.
Bruno Anthony: I beg your pardon, but aren't you Guy Haines?
Bruno Anthony: Everyone has somebody that they want to put out of the way. Oh now surely, Madam, you're not going to tell me that there hasn't been a time that you didn't want to dispose of someone. Your husband, for instance?
Guy Haines: It's pretty late to start flirting with a discarded husband.
Mrs. Anthony: Well, I do hope you've forgotten about that silly little plan of yours.
Bruno Anthony: Which one?
Mrs. Anthony: About blowing up the White House.
Bruno Anthony: Oh, Ma, I was only fooling. Besides, what would the President say?
Mrs. Anthony: You're a naughty boy, Bruno.
Mrs. Cunningham: You know, I read of a case once. I think it would be a wonderful idea! I can take him out in the car, and when we get to a very lonely spot, knock him on the head with a hammer, pour gasoline over him and over the car, and set the whole thing ablaze!
Bruno Anthony: [scowls] And have to walk all the way home? Oh, no.
Mrs. Cunningham: [meek] No? Oh...
Bruno Anthony: No, no. I have the best way, and the best tools.
Bruno Anthony: Simple, silent, and quick - the silent part being the most important. Let me show you what I mean. You don't mind if I borrow your neck for a moment, do you?
Mrs. Cunningham: [simpers] Well... if it's not for long!
Minister: [Last Lines] I beg your pardon, but aren't you Guy Haines?
[Guy and Anne get up and walk away without saying a word to the man]
Senator Morton: One doesn't always have to say what one thinks.
Bruno Anthony: How do you do, sir? I'd like to talk with you sometime, sir, and tell you about my idea for harnessing the life force. It'll make atomic power look like the horse and buggy. I'm already developing my faculty for seeing _millions_ of miles. And Senator: can you imagine being able to smell a flower - on the planet Mars? I'd like to have lunch with you someday soon, sir. Tell you more about it.
Bruno Anthony: I have a theory that you should do everything before you die.
Anne Morton: How did you get him to do it?
Guy Haines: I... get him to do it?
Anne Morton: He killed Miriam, didn't he?
[Guy stares at Anne, hesitating to answer]
Anne Morton: Tell me, didn't he.
Guy Haines: Yes. He's a maniac. I met him on the train going to Metcalf. He had some crazy scheme about exchanging murders. I'd do his murder; he'd do mine.
Anne Morton: What do you mean "your murder" Guy?
Guy Haines: He read about me in the papers. He knew about Miriam, about you. He suggested that if he got rid of Miriam for me I should kill his father.
Anne Morton: You must have known he was talking nonsense.
Guy Haines: But he wasn't! Of course I didn't give it another thought. And now a lunatic wants me to kill his father.
Anne Morton: It's too fantastic.
Guy Haines: Yes, isn't it?
Anne Morton: You mean, you've known about Miriam all this time?
Guy Haines: Since the first night. He gave me her glasses.
Anne Morton: Why didn't you call the policee?
Guy Haines: And have them say what you did? "Mr. Haines, how did you get him to do it?" And Bruno would say we planned it together.
Barbara Morton: Who's the interesting-looking Frenchman with the Darvilles?
Guy Haines: His name's Antony... he's not French.
