Trivia: The Tooth Fairy in Darkness Falls looks completely different from what was originally made. The studio had to go back and re-film and make The Tooth Fairy look less scary. Heres a website that shows what she originally looked like. http://www.spawn.com/toys/product.aspx?division=toys&category=movies&series=mm5&product=toothfairy.
Trivia: Nicole Kidman was originally cast as Frannie, but Meg Ryan insisted on playing the role and also auditioned, something unusual for famous actresses like her.
Trivia: The last conversation between Tom Arnold and that big guy is an obvious tribute to the conversation between the same two actors at the end of Exit Wounds. They even mention the latter in the former.
Trivia: The experiment that showed that humans lose 21 grams at the moment of death were later shown to be highly flawed. The entire experiment was based on only four people. Only the first subject actually lost 21 grams. Another person lost a different weight, and the other two died before they could be properly weighed.
Trivia: Choi Min-sik had to eat four live octopuses for the infamous scene in which his character Oh Dae-su wants to "eat something alive." Min-sik is a Buddhist, and would pray before each take and profusely apologize to the octopuses before eating them. The director later personally thanked the octopuses during an acceptance speech for an award he got for the film.
Trivia: It just so happened that on a day when they needed a wide angle lens to get a shot, for the over head view of Hank shooting through the wall at Nash, that the Spider-Man movie was being filmed only a few blocks away. The director of Spider-Man let the director of National Security borrow their lens long enough to get that shot, which was on screen for only about a second. (01:04:55)
Trivia: Writer/Director JT Petty got the approval to make this follow-up after a simple pitch. He went into a meeting and told the produces that he wanted to "make Hitchcock's 'Rear Window, ' except with giant cockroaches." Not only was it a novel approach to a sequel that allowed the studio to take the series in a new direction, but it also helped the production save money, since most of the film would be set in and around a single location (in this case an apartment complex.) He was given the greenlight almost immediately after.
