Duke Leto Atreides
- Paul Atreides: [From trailer] Dad, what if I'm not the future of House Atreides?
- Duke Leto Atreides: A great man doesn't seek to lead; he is called to it. But if your answer is no, you'd still be the only thing I ever needed you to be: my son.
- Duke Leto Atreides: We are House Atreides. There is no call we do not answer. There is no faith that we betray. The Emperor asks us to bring peace to Arrakis. House Atreides accepts!
- Duke Leto Atreides: Jessica. You gave me a son, and from the moment he was born I never questioned you. I trusted you completely, even when you walked in shadows. Now I'm asking you this one thing. If anything happens, will you protect our son?
- Lady Jessica Atreides: With... my life.
- Duke Leto Atreides: I'm not asking his mother, I'm asking the Bene Gesserit. Will you protect Paul?
- Lady Jessica Atreides: Why are you having these thoughts? Leto, this is not you.
- Duke Leto Atreides: I thought we had more time.
- Duke Leto Atreides: Dr. Kynes. You saw it. With your own eyes. It's plain to see. Everything they've left us is in shambles. We've been set up to fail.
- Liet Kynes: That carryall was just old. The desert isn't kind to equipment.
- Duke Leto Atreides: You know what will happen if I don't get spice production back on track.
- Liet Kynes: I'm not here to take your part. Arrakis has seen men like you come and go. Take good care of your family. The desert's not kind to humans, either.
- Duke Leto Atreides: [to Paul] Your grandfather said, "A great man doesn't seek to lead. He's called to it. And he answers." And if your answer is no, you'll still be the only thing I ever needed you to be, my son. I found my own way to it. Maybe you'll find yours.
- [Paraphrasing a quote from Atreides soldiers in the book]
- Duke Leto Atreides: What do they say about this hellhole again?
- Gurney Halleck: To shower, you scrub your ass with sand, my lord. That's what they say.
- Duke Leto Atreides: That's what they say.
- Atreides Soldier: We've got a full load of spice. We can't just leave it.
- Duke Leto Atreides: Damn the spice!
- Duke Leto Atreides: Here on Caladan, we've ruled by air power and sea power. On Arrakis we need to cultivate desert power.
