- Jack Muldoon: Joseph, we are parched!
- Bartender: We have run up a bloody big tab since noon, haven't we, Muldoon and I still haven't seen hide nor hair of anything green...
- Jack Muldoon: Now, Joseph, didn't I tell you? I have enough legal tender to buy this stinking pesthole of an island ten times over!
- Bartender: You said a lot of craxy things since you walked in here, but the people who don't cough me up the green find themselves playing footsy with the, eh... sharks.
- Dr. Elizabeth Merrill: You've got a way about you, Jake Muldoon. Too bad you're dealing with a cynic like myself.
- Jack Muldoon: Terrific chicks, most of them. They come from the Sandwich Islands, you know. Get my meaning? You don't get my meaning.
- Jack Muldoon: Hey, I warn you of certain danger and you wanna go on anyway? What are you, man? Some kind of martyr?
- Jack Muldoon: You guys can't depend on my for anything, can you, not even to let you down.
- Mark Harris: Why did you come back?
- Jack Muldoon: I hate to admit it, but I think I got a conscience or something. I mean, the farther away from here I got, the more guilty I felt.
- Jack Muldoon: That walking skyscraper, he's a menace.
- Mark Harris: He's a miner.
- Jack Muldoon: I don't care how old he is.
- Mark Harris: A prospector, did you not see his tools, this cabin?
- Thark: You steal from Thark? You ruin his work?
- Mark Harris: I am not a thief.
- Mark Harris: Go back to the well you crawled from, thief.
- Mark Harris: Not until I finish what I've come to do.
- Thark: To steal!
