There Will Be Blood

The book Sam finds that is concealing the button that unlocks Emily's room is titled, "How To Serve Man," - which references the 1950s short story, "To Serve Man." It tells about aliens who come to earth. At an UN session, the aliens tell the humans that they are there to provide them with peace and plenty. They supply them with cheap unlimited power, a device to suppress explosions, and drugs for prolonging life. One of the characters steals a book from the aliens and translates the title to "To Serve Man." He believes it is a guide the aliens use to 'provide for' and 'take care of' man. After further translation, he discovers that it is actually a cook book. This story aligns very closely with the Leviathan's plan for man: They are secretly purifying the gene pool, curing cancer, and ending hunger in order to harvest their perfect food supply... all with the public image of "serving man for the greater good."
