Mr. Green
- Mr. Green: So it was you. I was going to expose you.
- Wadsworth: I know. So I choose to expose myself.
- Colonel Mustard: Please, there are ladies present!
- Wadsworth: The key is gone!
- Professor Plum: Never mind about the key, unlock the door!
- [smacks Mr.Green on the shoulder]
- Mr. Green: [grabs Professor Plum by the collar, throttling him] I CAN'T UNLOCK THE DOOR WITHOUT THE KEY!
- [releasing Plum, Mr. Green rattles doorknob]
- Mr. Green: LET US IN! LET US IN!
- Colonel Mustard, Miss Scarlet: [on other side of locked door] LET US OUT! LET US OUT!
- [last lines]
- Mr. Green: They all did it. But if you wanna know who killed Mr. Boddy, I did. In the hall. With the revolver. Okay, Chief, take 'em away. I'm gonna go home and sleep with my wife.
- Wadsworth: ...and to make a long story short...
- Miss Scarlet, Mrs. White, Colonel Mustard, Mrs. Peacock, Mr. Green, Colonel Mustard: Too late!
- Mr. Green: [to Miss Scarlet] So, how did you know Colonel Mustard works in Washington? Is he one of your clients?
- Colonel Mustard: Certainly not!
- Mr. Green: I was asking Miss Scarlet.
- Colonel Mustard: [to Miss Scarlet] Well, you tell him it's not true.
- Miss Scarlet: It's not true.
- Professor Plum: [to Miss Scarlet] Is that true?
- Miss Scarlet: No, it's not true.
- Mr. Green: Ah ha! So it is true!
- Wadsworth: A double negative!
- Colonel Mustard: A double negative?
- [whispering]
- Colonel Mustard: You mean you have photographs?
- Wadsworth: That sounds like a confession to me. In fact the double negative has led to proof positive. I'm afraid you gave yourself away.
- Colonel Mustard: [angry, to Wadsworth] Are you trying to make me look stupid in front of the other guests?
- Wadsworth: You don't need any help from me, sir.
- Colonel Mustard: That's right!
- Yvette: But it is dark upstairs and I am frightened of the dark. Will anyone go with me?
- Professor Plum: I will!
- Colonel Mustard: I will!
- Mr. Green: No, thank you.
- Mrs. Peacock: What are you all staring at?
- Mr. Green: Nothing.
- Mrs. Peacock: Well who's there?
- Colonel Mustard: Nobody.
- Mrs. Peacock: What do you mean?
- Wadsworth: Nobody. No body, that's what we mean. Mr. Boddy's body, it's gone.
- Mrs. White: Maybe he wasn't dead.
- Professor Plum: He was!
- Mrs. White: We should've made sure.
- Mrs. Peacock: How?
- [muttering]
- Mrs. Peacock: By cutting his head off, I suppose.
- Mrs. White: That was uncalled for!
- Mrs. White: [after Mr. Green shoots Wadsworth] Are you a cop?
- Mr. Green: No, I'm a plant.
- Miss Scarlet: A plant? I thought men like you were usually called a fruit.
- Mr. Green: Very funny. FBI. That phone call from J. Edgar Hoover was for me.
- [opens the door]
- Mr. Green: Told you I didn't do it!
- Mrs. White: [after Mrs. Peacock swears that the reason she's being blackmailed is a vicious lie] Well, I am willing to believe you. I, too, am being blackmailed for something I didn't do.
- Mr. Green: Me too.
- Colonel Mustard: And me.
- Miss Scarlet: Not me.
- Wadsworth: [surprised] You're *not* being blackmailed?
- Miss Scarlet: Oh, I'm being blackmailed all right, but I did what I'm being blackmailed for.
- Mr. Green: What did you do?
- Miss Scarlet: Well, to be perfectly frank, I run a specialized hotel and a telephone service which provides gentlemen with the company of a young lady, for a short while.
- Professor Plum: Oh yeah?
- [pulls out pen and a pad of paper]
- Professor Plum: What's the phone number?
- Mr. Green: Who would wanna kill the cook?
- Miss Scarlet: Dinner wasn't that bad.
- Colonel Mustard: How can you make jokes at a time like this?
- Miss Scarlet: It's my defense mechanism.
- Colonel Mustard: Some defense. If I was the killer, I would kill you next.
- Miss Scarlet: Oh?
- [Everyone looks at Colonel Mustard]
- Colonel Mustard: I said, "if". *If*!
- Mr. Green: [gets up in front of everyone] I have something to say. I'm not going to wait for Wadsworth here to unmask me. I work for the State Department, and I'm a homosexual.
- [pause]
- Mr. Green: I feel no personal shame or guilt about this, but I must keep it a secret, or I will lose my job on security grounds.
- [pause]
- Mr. Green: Thank you.
- Mr. Green: You're Mr. Boddy!
- [Wadsworth laughs evilly]
- Professor Plum: Wait a minute. So who did I kill?
- Wadsworth: My butler.
- Professor Plum: Oh, shucks.
- Wadsworth: He was expendable like all of you. I'm grateful to you all for disposing of my network of spies and informers. Saved me a lot of trouble. Now there's no evidence against me.
- Professor Plum: [after learning who killed Mr. Boddy, the motorist, the cook, the cop, and Yvette] So it must've been Mr. Green who shot the singing telegram!
- Mr. Green: I didn't do it!
- Colonel Mustard: Well, there's nobody else left.
- Mr. Green: But I didn't do it! The gun is missing! Whoever's got the gun shot the girl!
- Wadsworth: [extracts his gun] I shot her.
- Professor Plum: [pointing to Mrs. Peacock's drink] Maybe he was poisoned!
- [Mrs. Peacock immediately drops her glass full of brandy and starts screaming]
- Mr. Green: [trying to get her to the couch] Mrs. Peacock, please. Mrs. Peacock, it's alright. It's alright. We don't know anything. Sit-sit down, sit down, Mrs.-
- [slaps her; everybody stares]
- Mr. Green: Well, I had to stop her from screaming!
