The machine's "name" of "Ernest Thornhill" is most likely a nod to the classic Alfred Hitchcock film "North By Northwest." In the POI episode "Zero Day," Finch and Reese learn that the machine gave them the number of a "Ernest Thornhill," a person they soon realize does not exist. In "North By Northwest," Cary Grant plays Roger O. Thornhill, who is attempting to track down a man named Kaplan, a person Grant's character eventually learns does not exist. Furthermore, "North By Northwest" was written by screenwriter Ernest Lehman. See more
