Steve Zissou: Don't point that gun at him, he's an unpaid intern.

[a woman asks a question about the shark Zissou is hunting]
Festival Director: [translating] That's an endangered species at most. What would be the scientific purpose of killing it?
Steve Zissou: Revenge.

[last lines]
Steve Zissou: This is an adventure.

Steve Zissou: We'll split into two groups. I'll take Ned, Ogata, and Wolodarsky.
Klaus Daimler: [pouting] Thanks. Thanks a lot for not picking me.

Jane Winslett-Richardson: Are we - are we safe in here?
Steve Zissou: I doubt it.
Klaus Daimler: Do you still want to blow him up?
Steve Zissou: No, we're out of dynamite anyway.
Eleanor Zissou: It is beautiful Steve.
Steve Zissou: Yea, it's pretty good isn't
it... I wonder if it remembers me...

[Steve bursts to the surface from an underwater dive, shouting hysterically]
Klaus Daimler: Steve!
Steve Zissou: Vikram, is that thing rolling?
Klaus Daimler: Where's Esteban?
[Written text of what Steve is shouting rolls onto the screen as he speaks]
Steve Zissou: Encounter with highly abnormal
shark-like fish! Ten meters in length! Unfamiliar dorsal features! Spots all over it! I shot it dorsally with a homing dart!
[shouts]
Steve Zissou: Esteban was eaten!
Klaus Daimler: Is he dead?
Steve Zissou: Esteban was eaten! Check the scanning monitor before it dives too deep!
Klaus Daimler: He
was bitten?
Steve Zissou: Eaten!
Klaus Daimler: [shocked] He was swallowed whole?
Steve Zissou: No! *Chewed*!
Klaus Daimler: [to the camera] He's got hydrogen psychosis, the crazy-eye!
[camera zooms in on Steve's face - his eyes are dilated ridiculously large]
Klaus
Daimler: Steve! They say you've got crazy-eye!
[to the camera]
Klaus Daimler: Get him out of the fucking water!
Steve Zissou: [shouting] Check the scanning monitor!
Klaus Daimler: Steve!
[Klaus jumps into the water to get Steve, still wearing all of his normal clothes and not bothering to take his shoes
off]
Steve Zissou: [shouting] Esteban! Esteban! Esteban!

Steve Zissou: Wolodarsky, go get the keys to that fishing boat, and throw them in the water. No, wait. They might have another set. Just blow it up.

Eleanor Zissou: Your cat's dead.
Steve Zissou: What? Which one?
Eleanor Zissou: Marmalade. I'm sorry.
[lighting cigarette]
Steve Zissou: What happened?
Eleanor Zissou: A rattlesnake bit it in the throat.
Steve Zissou: [pause] Goddammit, Elanor, why do have
to say it like that? You couldn't try to break it a little bit nicer?

[Hennessey is playing poker with Filipinos who have kidnapped him and Zissou bursts into the room accidentally]
Alistair Hennessey: Steven, are you rescuing me?
[pause]
Alistair Hennessey: Fold.
[a pirate quickly shoots Hennessey in the chest, knocking him backwards in his chair and down to the floor - large gunfight begins]
