- James Blackthorn aka Butch Cassidy: Sometimes I think there's only two moments in a man's life: the one is when he leaves home, and the other one is when he returns. Everything else is just in the middle.
- Mackinley: An army battalion is on its way here. I sent for them. This is the most important thing to have happened around here since, well, since your death.
- Title Card: Butch Cassidy was one of the most wanted outlaws in North America in the early 20th century, leading legendary gangs like the Wild Bunch and the Train Robbers Syndicate. Hounded by the law and big companies, he fled to South America with his friend the Sundance Kid. Both were supposedly killed in a shootout with the Bolivian army in San Vicente, Bolivia, in 1908. Recently investigators analyzed remains found at the location where witnesses had claimed they were buried. They were not there.

- James Blackthorn aka Butch Cassidy: Dear Ryan, I reckon you're feeling a little lonely now that your mother's gone. You're too young for something like this. I know she must have told you about me, and I for one never stopped thinking about you. Even though I've never seen you, I'd bet my best memories that I'd recognize you in the blackest night. These past years have been hard on us all. Very few of us are still around. The land were I live now is a good one. Quiet people, peaceful for the most part. But it's not home. That's why it's time for me to come back. Burn this letter when you read it, like you mother would have done, and wait for me. Much love. - Your Uncle.
- James Joven: [about Etta] She's handy. You teach her?
- Sundance: I don't think anyone ever taught her anything. And it's about time you learned her name.
- James Blackthorn aka Butch Cassidy: [showing that he took his bullets] You're empty son.
- Ing. Eduardo Apodaca: You son of a bitch.
- James Blackthorn aka Butch Cassidy: [chuckling] Yeah. You should'a heard what they called me in Wyoming.
- James Blackthorn aka Butch Cassidy: You're rich, right? I mean your family.
- Ing. Eduardo Apodaca: Well, I guess it depends on who you compere me too.
- James Blackthorn aka Butch Cassidy: Poor people.
- James Blackthorn aka Butch Cassidy: [writing in his letter] Friendship is the most valuable thing a man can have. It's worth more than money, land, horses, or cattle. It might be the only thing you never forget.
- James Blackthorn aka Butch Cassidy: One day I woke up and found myself alone. Seemed like everybody I knew was either dead or in jail. They thought I was dead too. So I just did what any good dead person would do; I went off and raised me some horses. Twenty years.
- Ing. Eduardo Apodaca: [posse approaching] James, I'm glad I'm with you.
- James Blackthorn aka Butch Cassidy: You know, before I met you - damn the day - I thought if I was gonna die of old age, I might as well go back home to do it. But hell, this seems like a good a day as any to die.
- Ing. Eduardo Apodaca: We're not going to die, old man.
- James Blackthorn aka Butch Cassidy: Of course not son, nobody ever does.
- James Blackthorn aka Butch Cassidy: [to Pinkerton agent] What the fuck are you doing in Bolivia? Don't you have anything better to do? And where's my pistol?
- Sundance: [wounded in the Andes mountains] Everybody'll think were dead, and look at us, strong as trees.
- James Joven: Snow-covered trees.
- Mackinley: There are times when you prefer to be dead, don't you agree? Hasta nunca, Mr. Blackthorn...
- James Blackthorn aka Butch Cassidy: See, one day I woke up and found myself alone. Seemed like everybody I knew was either dead or in jail. They thought I was dead, too, so I did what any good dead person would do: I went off and raised me some horses. Twenty years. That was a big change. Quiet times. See, I'm too long in the tooth to blow off and be what I used to be, you know, just an ordinary old bandit.
- Ing. Eduardo Apodaca: You should have become a rancher, too. You'd be rich now, instead of being here with me.
- James Blackthorn aka Butch Cassidy: Rich? I've been my own man. There's nothing richer than that.
- James Blackthorn aka Butch Cassidy: [after medicating the Spaniard for saddle sores] Your ass is softer than a bookkeeper's.
