- Coatl: I think of what you do for me in Spain. I think I speak to you now. Maybe I understand better why you come here. This is my country, senor. These are my people, my gods. We not come tell you to stop loving your gods. We not come to make you slaves. Why do you do this, senor?
- Pedro De Vargas: Well, I'm afraid I haven't any answer for that. It isn't right for men to worship idols. There's only one true God.
- Coatl: Maybe your God and my God same God. Maybe we just call him by different names.
- Pedro De Vargas: [reacting to the torture of his sister] I'll confess anything if you'll just release her!
- Don Francisco De Vargas: No! Do not save her by a lie! Silva, if you do this thing, look to your own soul!
- Prof. Botello: Even my skill cannot defeat the will of God, but I've stopped the bleeding. You'll have to admit it's a well-sealed wound!

- Hernando Cortez: Gentlemen, this time last year we were fighting mosquitos in swamps, accepting paltry gifts, and half-starving. But now we stand knocking at the very door of the great Emporer Moctezuma. We shall meet with His Majesty face-to-face - have done with ambassadors and specks of gold. This, gentlemen, is just the beginning!
- Jail guard: Senor el Supremo, the girl is dead!
- Diego De Silva: You bumbling fools! Have you no skill in your craft?
- Juan Escudero: Believe me, gentlemen, a lame goat takes no siesta. If something's got to be done, do it.
- Pedro De Vargas: [finding Botello lying on the ground] Botello, what happened?
- Prof. Botello: [groans] What misery! I'm lucky to be alive! Oh, my poor head!
- Pedro De Vargas: But what happened?
- Prof. Botello: You won't tell on me, Pedro lad?
- Pedro De Vargas: Of course not!
- Prof. Botello: I was just taking a stroll with one of those Indian ladies - ugly as sin, of course, color of mud, but charming, dear boy, charming.
- Pedro De Vargas: You know the penalty for touching an Indian!
- Prof. Botello: Now, now, Pedro, you know orders don't apply to a cockroach like me.
- Hernando Cortez: Before this adventure is concluded, gentlemen, we will taste the joys of victory or the bitterness of defeat. Many will die in the days that lie ahead. But those who survive will one day return to their homeland, rich in wisdom and gold, exonerated by his majesty and forever secure in the knowledge that they had participated in the opening of a new world.
