Mike Brody: White sharks are dangerous. I know 'em. My father, my brother, myself. They're murders.
Kathryn Morgan: Overman was killed inside the park. The baby was caught inside the park. Its mother is inside the park.
Kathryn Morgan: Our shark couldn't have killed Overman. Its mother did.

Fred: Why don't we blow it up?
Calvin Bouchard: Listen, nephew. There's a $2-1/2 million turbine that's not gonna go up in smoke because of some damn fish! Shut the pumps down!
Philip FitzRoyce: Then perhaps we can have a drink and some dinner tonight?
Kathryn Morgan: Oh, I'm sorry, Mr. FitzRoyce, but that's a behavior I just don't do.
