Question: What happened to cause people to be vampires? Title: Daybreakers Movie plot: This article's plot summary may be too long or excessively detailed. Please help improve it by removing unnecessary details and making it more concise. (November 2015) (Learn how and when to remove this template message) In 2009, a plague caused by an infected vampire bat has transformed most of the world's population into vampires and due to this event, control of the world no longer belongs to humans. The vampires are incapable of aging or dying from natural causes, but are unprotected against sunlight or any ultraviolet light. The entire vampire world is active at night, and various technological and architecture advances are made to adjust the populated areas to vampires' night cycle (such as UV protective cars, underground railways and paths across the cities, and UV warnings). However, human numbers quickly dwindle, and the need for blood becomes desperate. When deprived of blood for extended periods, vampires degenerate into "subsiders," psychotic bat-like creatures who lose their memories and independent thought and are left with the basic need for blood. Humans are captured and harvested in laboratory farms while scientists research a synthetic blood substitute to satisfy vampires' blood hunger across the world, while animal blood is also widely used. In 2019, Edward Dalton (Ethan Hawke) is the head hematologist for the pharmaceutical company Bromley Marks, the largest supplier of human blood in the United States. Along with fellow hematologist Christopher Caruso (Vince Colosimo), Dalton is in the process of developing a substitute to bolster dwindling blood supplies and to create a substance that can replace blood and be generated as required. The need is underscored after Dalton's boss, company owner Charles Bromley (Sam Neill), reveals that the estimated human population is down to 5%, and national blood supplies will not last more than a month. Faced with this knowledge, Edward and Chris carry out a hasty clinical trial of the latest revision on a volunteering soldier, which is a spectacularly...???

Question: Willoughby wants to use the newspaper salary to do what? Title: Meet John Doe Movie plot: Infuriated at being told to write one final column after being laid off from her newspaper job, Ann Mitchell (Barbara Stanwyck) prints a letter from a fictional unemployed "John Doe" threatening suicide on Christmas Eve in protest of society's ills. When the letter causes a sensation among readers, and the paper's competition suspects a fraud and starts to investigate, editor Henry Connell (James Gleason) is persuaded to rehire Mitchell, who schemes to boost the newspaper's sales by exploiting the fictional John Doe. From a number of derelicts who show up at the paper claiming to have written the original letter, Mitchell and Connell hire John Willoughby (Gary Cooper), a former baseball player and tramp in need of money to repair his injured arm (by Bonesetter Brown), to play the role of John Doe. Mitchell starts to pen a series of articles in Doe's name, elaborating on the original letter's ideas of society's disregard for people in need. Willoughby gets $50, a new suit of clothes, and a plush hotel suite with his tramp friend "The Colonel" (Walter Brennan), who launches into an extended diatribe against "the heelots", lots of heels who incessantly focus on getting money from others. Proposing to take Doe national via the radio, Mitchell is given $100 a week by the newspaper's publisher, D. B. Norton (Edward Arnold), to write radio speeches for Willoughby. Meanwhile, Willoughby is offered a $5,000 bribe from a rival newspaper to admit the whole thing was a publicity stunt, but ultimately turns it down and delivers the speech Mitchell has written for him instead.[3] Afterward, feeling conflicted, he runs away, riding the rails with the Colonel until they reach Millsville. "John Doe" is recognized at a diner and brought to City Hall, where he's met by Bert Hanson (Regis Toomey), who explains how he was inspired by Doe's words to start a "John Doe club" with his neighbors. The John Doe philosophy spreads across the country, developing into a broad grassroots movement whose simple slogan is, "Be a better...???

Title: Fish Tank Movie plot: Mia Williams is a volatile and socially isolated 15-year-old. She lives on an East London council estate with her single mother, Joanne, and younger sister, Tyler, and is highly antagonistic toward both of them. Mia is a loner, appearing to have had a falling out with her best friend Keely. She provokes Keely's other friends and head butts another girl when Mia criticises their dance routine. Mia regularly practises hip-hop dance alone in a deserted flat. Near the estate, Mia comes across a skinny, tethered horse in a Traveller encampment. She tries to free it, only to be caught, taunted, and assaulted by two young men, the horse's owners. A third young man, Billy, the brother of the other two, is more sympathetic. He shows kindness towards Mia and explains that the horse is old and ill. Joanne's new boyfriend, Conor O'Reily, is a charming and handsome Irishman. He drives them on a day-trip into the countryside, intent on making a good impression with the daughters. He introduces them to his favourite song, Bobby Womack's version of "California Dreamin'", shows Mia how to catch a fish using noodling, and asks her to show off her dance moves. Although Mia is abrupt with Conor, she appears to be intrigued by him. Mia goes to a cybercafe and watches amateur breakdancing videos on YouTube. Just as Mia is about to leave, she finds a flyer for a club seeking dancers and at the door, Keely's friends enter and they exchange taunts.
