- Lt. Ainsley: Morning, doctor. The Admiral has a job for your fish.
- Dr. Elizabeth Merrill: His name is Mark Harris.
- Adm. Dewey Pierce: [to Mark Harris] Orders are: when people older and wiser tell us what to do, we do it. That's how we get things done, by obeying orders. And as long as you're here, you have to obey orders too.
- Mr. Schubert: Tell me, how did you manage to get here?
- Mark Harris: I swam.
- Mr. Schubert: Aha...
- [laughs]
- Mr. Schubert: Yeah, the fish told you how to reach our door?
- Mark Harris: I do not speak the language of fish. The inner current took me to the deep sound channel and a I listened to the whales talk.
- Mr. Schubert: Look at this stuff: all that's left of Russian spyships, CIA aircraft, French supersubs filled to the brim with secret hardware. I find it and fix it up and put it to work. I am the original recycle king.
- Mr. Schubert: For three thousand years, they've destroyed our land, air, water. Now they're gonna finish each other off in one last big war.
- Mark Harris: How do you know that?
- Mr. Schubert: Well, mainly 'cause I'm gonna start it.
- Dr. Elizabeth Merrill: So we took every scrap of information we had and fed it to the WRW 12000 at the Defence Department. And the computer sent back an anwer.
- [she taps a few buttons and the following text appears on a computer screen: Last Citizen of Atlantis ?]
- Mr. Schubert: Before we came along, the idea of a sea mountain habitat was just a bunch of chicken tracks on piece of paper. But we made it work. And I'll tell you the secret: make friends with the ocean.
- Ernie Smith: Hey, Popeye! Where's the five you owe?
- Popeye: Where's the broad you owe me, you yoyo?
- Ernie Smith: [to Mark Harris] This is Popeye, big as an ox and twice as smart.
- Mr. Schubert: Forgive me, my affliction is the result of warped adulthood toppled with an insatiable desire to be friendly. And I do want to be friendly with you. Come join me Mark, lets be friends.
- Dr. Elizabeth Merrill: Oh, I'm sorry, this is such a bore...
- Dr. Doug Berkley: I like surface parties.
- Dr. Doug Berkley: Well I don't. If I'm not working, I'd rather be diving. You know, I start to get withdrawal symptoms if I'm out of the water too long.
- Dr. Doug Berkley: Can that be your only hobby?
- Dr. Elizabeth Merrill: What else is there?
- Mr. Schubert: I figure you're to be a marine biologist. You heard about us from some colleague and you stowed away on our shuttle to see for yourself.
- Mark Harris: I am a citizen of the ocean.
- Mr. Schubert: Well... well, we got a lot in common. I was a seagoing junkman for twenty years, until I got smart. And now that I am smart, and rich, and difficult, I get what I want.
