New Lost theory
Lost is They Live and Sayid is Roddy Piper. Quoting wiki:
The idea for They Live came from two sources: a short story called "Eight O'Clock in the Morning" by Ray Nelson, originally published in The Magazine of Fantasy and Science Fiction in the 1960s, involving an alien invasion in the tradition of Invasion of the Body Snatchers, and a story called "Nada" from the Alien Encounters comic book. John Carpenter describes Nelson's story as "a D.O.A. type of story, in which a man is put in a trance by a stage hypnotist. When he awakens, he realizes that the entire human race has been hypnotized, and that alien creatures are controlling humanity. He has only until eight o'clock in the morning to solve the problem." Carpenter acquired the film rights to both the comic book and short story and wrote the screenplay using Nelson’s story as a basis for the film's structure.
