Without Doc Holliday, that movie would have been very mediocre.
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!"]
True words, sir
