J. J. Abrams has said "Cloverfield" lay dormant in the Mid-Atlantic Ridge, until it was hit by a falling satellite owned by the fictional Japanese drilling company Tagruato. Abrams described the creature as a "baby" who has been underwater for thousands of years who is "confused, disoriented, and irritable" when he comes out, and Goddard pointed out the lack of explanation in the film of the creature's origin was deliberate. Reeves described the creature's reaction to its surroundings, "It’s this new environment that it finds frightening."
They dragged her away because she had been bitten by the flea-parasites the monster carried around on its skin. Something in their saliva causes a severe reaction in humans. She later exploded, and that was why they had to get her away from the public.
The director said that "Cloverfield" was the government's case designate for the monster, comparing the titling to that of the Manhattan Project. "And it's not a project per se. It's the way that this case has been designated. That's why that is on the trailer, and it becomes clearer in the film. It's how they refer to this phenomenon [or] this case," said the director. The film's final title, "Cloverfield", is the name of a main street in Santa Monica, CA, near Abrams's office.
No, it didn't really happen, silly. It's a fictional movie told from the point of view from a hand-held camera. That's just how the movie was filmed. It didn't really happen. If it did, it would have been all over the news, not the big screen.
Apparantly it didn't die. At the end of the movie, after all of the credits, you can hear Rob say "It's still alive." Plus, if it could survive behind hit in the head with a satillite and pummeled by Stealth Bomber bombs as well as tank and jet fire, I'm pretty sure the little cretin could survive any thing. . .
