Tombstone, my favorite western, and the definitive portrayal of Doc Holliday (Val Kilmer):
Here's a great scene:
JOHNNY RINGO
[Ringo steps up to Doc] And you must be Doc Holliday.
DOC HOLLIDAY
That's the rumor.
JOHNNY RINGO
You retired too?
DOC HOLLIDAY
Not me. I'm in my prime.
JOHNNY RINGO
Yeah, you look it.
DOC HOLLIDAY
And you must be Ringo. Look, darling, Johnny Ringo. The deadliest pistoleer since Wild Bill, they say.
What do you think, darling? Should I hate him?
KATE
You don't even know him.
DOC HOLLIDAY
Yes, but there's just something about him. Something around the eyes, I don't know, reminds me of... me.
No. I'm sure of it, I hate him.
WYATT EARP
[to Ringo] He's drunk.
DOC HOLLIDAY
In vino veritas.
["In wine is truth" meaning: "When I'm drinking, I speak my mind"]
JOHNNY RINGO
Age quod agis.
["Do what you do" meaning: "Do what you do best"]
DOC HOLLIDAY
Credat Judaeus apella, non ego.
["The Jew Apella may believe it, not I" meaning: "I don't believe drinking is what I do best."]
JOHNNY RINGO
[pats his gun] Eventus stultorum magister.
["Events are the teachers of fools" meaning: "Fools have to learn by experience"]
DOC HOLLIDAY
[gives a Cheshire cat smile] In pace requiescat.
["Rest in peace" meaning: "It's your funeral!"]
MARSHAL WHITE
Come on boys. We don't want any trouble in here. Not in any language.
DOC HOLLIDAY
Evidently Mr. Ringo's an educated man. Now I really hate him.
Another scene:
BILLY CLANTON
Stephen Foster. "Oh, Susannah", "Camptown Races"... Stephen stinkin' Foster?!
DOC HOLLIDAY
Ah, yes. Well, this happens to be a nocturne.
BILLY CLANTON
A which?
DOC HOLLIDAY
You know -- Frederic fucking Chopin?
Another:
BILLY CLANTON
Why, it's the drunk piano player. You're so drunk, you can't hit nothin'. In fact, you're probably seeing double.
[Billy Clanton draws a knife]
DOC HOLLIDAY
[takes out a second gun] I have two guns, one for each of ya'.
Other lines:
"I'm your huckleberry."
"Ed, what an ugly thing to say. I abhor ugliness. Does this mean we're not friends anymore? You know Ed, if I thought you weren't my friend, I just don't think I could bear it."
"Why Ike, whatever do you mean? Maybe poker's just not your game, Ike. I know! Let's have a spelling contest!"
"Why Kate, have you no kind words for me as I ride away? [pause] I calculate not." [rides off]
