- Dr. Charles Goodfellow: I can't understand why I never win.
- Dr. John 'Doc' Holliday: You don't play very well. Besides that, you never cheat.
- Dr. John 'Doc' Holliday: Well, you got the first gun for your posse.
- Wyatt Earp (Tombstone city marshal: Did you hear the part about "no funds available"?
- Dr. John 'Doc' Holliday: I hear the Chamber of Commerce has put up $20,000 reward money.
- Wyatt Earp (Tombstone city marshal: For arrest and conviction, not dead or alive. Not your style, Doc.
- Dr. John 'Doc' Holliday: For that kind of money, I can be as law abiding as, ah, you are.
- Wyatt Earp (Tombstone city marshal: You gonna be all right?
- Dr. John 'Doc' Holliday: Except for a slight dying spell.
- Denver doctor: You know, you don't have to get well to please me. I'm used to people dying on me.
- Dr. John 'Doc' Holliday: So am I.
- [the judge has just thrown out the murder charges against the Earps and Doc Holliday after the gunfight at the O.K. Corral]
- Dr. John 'Doc' Holliday: Well, shooting you from the front side didn't work. Next time he'll try it from the back.
- [the mortally wounded Morgan Earp whispers in Wyatt's ear]
- Dr. John 'Doc' Holliday: What did he say?
- Wyatt Earp (Tombstone city marshal: When we were kids, we used to argue about whether when you were dying, your whole life flashed in front of you or not. He said, "It ain't so, Wyatt."
- Wyatt Earp (Tombstone city marshal: A man's life... for fifty dollars. I'm gonna give you a chance to make another fifty dolars.
- Andy Warshaw: I don't want such a chance.
- Wyatt Earp (Tombstone city marshal: My men will stay back. I'm gonna count one, two, three. You can draw on two - I'll wait to three. If you get me, my boys won't bother you.
- County Sheriff Jimmy Bryan: You're under arrest.
- Wyatt Earp (Tombstone city marshal: For what?
- County Sheriff Jimmy Bryan: Murder
- Wyatt Earp (Tombstone city marshal: Not today, tomorrow or ever. You have no jurisdiction in the city of Tombstone. Even if you did you couldn't make it stick.
- Frank Stilwell: We got enough men behind us to make it stick.
- [Doc cocks his shotgun]
- Dr. John 'Doc' Holliday: Stilwell, if you so much as turn your head towards those men, you'll be laying in the horse manure with your friends.
- Ike Clanton: Get this through your heads. If this was the east, I could make law the way they do. But the best I can do out here is buy it.
- [the murder charges against Clanton's gang have been thrown out]
- Wyatt Earp (Tombstone city marshal: I don't want to hear a word out of you.
- Dr. John 'Doc' Holliday: I'm just educating myself. I've never been on the right side of the law before. I want to see how much good it does you when you are.
- [Wyatt re-introduces Doc to the Tucson sheriff]
- Wyatt Earp (Tombstone city marshal: You know Doc Holliday. Sherm McMasters.
- Dr. John 'Doc' Holliday: You were the arresting officer when I shot Long Nose Ernie here in '74.
- Tucson Sheriff Sherman McMasters: That's right.
- Dr. John 'Doc' Holliday: Good to see you.
- Wyatt Earp (Tombstone city marshal: I don't care about the rules anymore. I'm not that much of a hypocrite.
- Dr. John 'Doc' Holliday: The whole thing is hypocrisy. The rules they tack on today that unless you're wearing that badge or a soldier's uniform, you can't kill. But they're the only rules there are. They are more important to you than you think. Play it that way, Wyatt, or you'll destroy yourself.
- Dr. John 'Doc' Holliday: You got some kind of plan?
- Wyatt Earp (Tombstone city marshal: I have.
- Dr. John 'Doc' Holliday: Want to tell me about it?
- Wyatt Earp (Tombstone city marshal: We take whoever gets in our way.
- Dr. John 'Doc' Holliday: You call that a plan?
- Wyatt Earp (Tombstone city marshal: You got a better one?
- Horace Sullivan: Just a moment, Your Honor. I should like to reexamine the defendant.
- Horace Sullivan: [as Earp sits in the witness chair] Wyatt, did malice move you against the Clanton group?
- Wyatt Earp (Tombstone city marshal: No.
- Horace Sullivan: Would you tell the court what did?
- Wyatt Earp (Tombstone city marshal: The Clanton group was armed and made threats of death and violence against us. It was our duty as sworn peace officers to disarm and arrest them. I would disarm and arrest General Ulysses S. Grant if he appeared on the streets of Tombstone under those circumstances.
- County Sheriff Jimmy Bryan: Wyatt, I told you before you went down to the corral that I had met with the Clanton group and they agreed to leave town peaceably.
- Wyatt Earp (Tombstone city marshal: Bryan, you take bribes. You're a thief, a liar, and a disgrace to your office. I wouldn't take your word if you swore to it on your mother's grave.
- County Sheriff Jimmy Bryan: You'll live to regret that.
- [first lines]
- [The Earps and Doc Holliday approach the O.K. Corral]
- Wyatt Earp (Tombstone city marshal: Ike Clanton, Andy Warshaw, Latigo, Curly Joe Brocious... Who's in the corral, Virg?
- Marshal Virgil Earp: Billy Clanton and the McLowerys.
- John P. Clum: Wyatt, the law won't work when part of it is ignored because everyone is either bought off or terrified.
- Wyatt Earp (Tombstone city marshal: Then I'll enforce the part that does work!
- Herman Spicer: [the Tombstone Judge begins his summation of the case against Wyatt Earp and others] So we see that the prosecution has introduced a substantial body of evidence pointing to the guilt of the defendants. And much of this stands unrefuted by the defense. But in the last analysis, the prosecution's case turns on two points. Whether in fact the shooting was a crime, and whether there was a motive.
- Herman Spicer: [continues] As to the first point, both the coroner's report and the independent medical testimony indicate that William Clanton's wrist was penetrated from the outside and that the bullet lodged in his abdomen. That is not the wound received by a man with his hands in the air.
- Herman Spicer: [continues] Tom McLowery's wounds were not the sort that could be received with his hands on his lapels like that, but rather with his hands around a Winchester carbine which he had recently extracted from his horse's saddle holster. The testimony of Sheriff Bryan therefore stands refuted.
- Herman Spicer: [concludes] Therefore, since no crime has been established... or even a motive for one... I find that the defendants were fully justified in their actions, and that these homicides occurred in the discharge of their official duties. The case of the prosecution is therefore dismissed. Court is adjourned.
- County Sheriff Jimmy Bryan: [demonstrating what he saw in the shooting] I watched them. I saw Billy Clanton and Frank McLowery raise their hands above their heads... Tom McLowery threw back his coat and label to show that he was unarmed! and that's when the Earps and Holliday opened fire.
