The Thing is a 1982 American science fiction horror film directed by John Carpenter from a screenplay by Bill Lancaster. Based on the 1938 John W. Campbell Jr. novella Who Goes There?, it tells the story of a group of American researchers in Antarctica who encounter the eponymous "Thing", an extraterrestrial life-form that assimilates, then imitates, other organisms. The group is overcome by paranoia and conflict as they learn that they can no longer trust each other and that any of them could be the Thing
