Corrected entry: When Dr. Rumack says, "Everyone who has eaten fish for dinner, will become violently ill in the next two hours."

Corrected entry: During the disco dance scene, Ted hurls Elaine towards the ceiling and stands there looking up, waiting for her.

Corrected entry: It is obvious that the two girl scouts who have the fight are stuntmen dressed as women.
Corrected entry: When Captain Oveur is summoned to the white courtesy phone, he picks up the red one at first and is told "No - the white phone." He replies "Oh."

Corrected entry: When the passengers start getting sick, the pilot radios to Chicago and says, "We're in trouble." Then, they find out that the fish is causing the sickness and the pilot passes out.

Corrected entry: One of the black characters orders a steak, but later in the movie, he is sick from eating the fish.
