Please answer the following question: I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: Cloverfield Movie plot: The film is presented as found footage from a personal camcorder recovered by the United States Department of Defense. A disclaimer states that the footage is of a case designated "Cloverfield" and that it was found in area US447, "formerly known as Central Park". The video consists primarily of segments taped the night of Friday, May 22. Occasionally, older segments are shown from a previous video that was taped over. The first video segment shows Beth waking up on the morning of Monday, April 27, having had sex with Rob, a previously platonic friend, who is filming her. They make plans to go to Coney Island that day. The footage then cuts to the evening of Friday, May 22, when Jason, Rob's brother, and his girlfriend, Lily, prepare a farewell party for Rob, who will be moving to Japan. Their friend Hud uses the camera to film testimonials during the party. After Beth has an argument with Rob and leaves the party, an apparent earthquake strikes, and the city suffers a brief power outage. The local news reports that an oil tanker has capsized near Liberty Island. When the party-goers leave the building, the severed head of the Statue of Liberty is hurled into the street in front of them. Hud records what appears to be an enormous creature several blocks away causing the Woolworth Building to collapse. Later, during the evacuation of the city, the creature's gigantic tail destroys the Brooklyn Bridge, killing Jason and several other people. News reports show the Army National Guard's 42nd Infantry Division attacking the monster. Smaller "parasite" creatures fall off its body and attack nearby pedestrians and soldiers.[5] Rob listens to a phone message from Beth, saying she is trapped in her apartment and unable to move. Going against the crowd, Rob, Hud, Lily, and Marlena (another party guest) venture into Midtown Manhattan to rescue Beth. They get caught in a battle between the creature and the National Guard and run into the Spring Street station, where they are attacked by several of the parasitic creatures... My question: Who is filming Beth?
A:
Rob.
