Trivia: The viral marketing story is incorporated into several parts of the movie. The first is the Slusho! shirt worn by Jason, given to him by Rob. Rob is leaving to work for Slusho! in Japan per his myspace account. Slusho! is owned by Tagruato Corporation, a company whose primary operations is off-shore drilling rigs. The company's logo is visible on the Tanker that is on fire during the Brooklyn Bridge scene. The Easter eggs show the destruction by the monster of Tagruato's Chaui drilling facility located about 2,000 off-shore of NY. The online viral character Jamie is seen passed out on the couch at the party. Her boyfriend, Teddy, who works for Tidowave, is seen on the bridge. Tidowave is an anti-Tagruato operation. At the end, while the camera looks over the Atlantic ocean, you'll see a falling object. The producer, JJ Abrams, has stated that this can be interpreted one of two ways: It's the monster falling out of the sky, or, a satellite which Tagruato reported on their website that they were actively assisting the Japanese government to locate.
Trivia: After the people flying in the helicopter get swatted down by the monster, during the period of time when they hit the ground and the camera seems to "skip," pay close attention to the static. You will get a few frames of the two characters on a ferris wheel and for almost exactly one frame of the movie you will get a shot of King Kong in the old King Kong movie. Obviously a tribute to other monster movies from the past.
Trivia: In an interview, the director says he left a clue as to where the monster came from at the end of the movie, where the camera is overlooking the ocean. A missle shaped object can be seen in the right corner of the screen, hitting the water. He said that in the sequel he would clarify more on what that means.
