Trivia: When the main agent verifies his hand against the screen, one of the pieces of information listed is 'Sector 7G'. This is where Homer Simpson works at the Springfield Nuclear Power Plant.

Trivia: When Jimmy & Jordan are talking about their plans for their last night together, Jimmy says that he and Nick are having cocktails with their psych. prof. and that Jordan could come too. She says no and "call me later and if not I guess I'll just meet you at the party."

Trivia: During the film's original outdoor reception Jake carries Melanie, who feigns death after having supposedly been struck by a lightening bolt, towards the wedding guests. Jake announces, "Melanie Carmichael is dead" but then a few seconds later he says, "Long live Felony Melanie." Jake and Melanie do this as a practical joke. The reaction of Melanie's mother at the supposed death of her daughter apparently upset the test audiences so much, that the production crew reshot the whole reception scene, minus the practical joke.
Trivia: Winona Ryder's onerous contractual stipulation about her being provided a bowl of Mike 'n' Ikes with the cherry ones removed was based on the rock band Van Halen's actual contract, which contained a similar clause about green M&Ms. Its purpose was to ensure that the rest of the contract would be followed to the letter.
Trivia: In the biblical book of Jonah, there is actually no whale that swallowed Jonah. The "whale" is a mistranslation of the Hebrew word for a big fish by the translators of the King James Version. Because of the prominence, respectability, and the wide distribution (it is in the public domain in the U.S., but not in the U.K.) of the King James translation over modern translations like the New International Version, the "whale" is what most Bible readers think of the sea creature that swallowed Jonah.
Trivia: Did anyone else pick up the Indiana Jones and the Temple of Doom rip-off/reference?

He then busts out the window and jumps out of it.
