Columbia, before production eventually moved to Los Angeles to accommodate Duchovny. The series later returned to Vancouver to film The X-Files: I Want to Believe as well as the tenth and eleventh seasons of the series. The X-Files was a hit for the Fox network and received largely positive reviews, although its long-term story arc was criticized near the conclusion. Initially considered a cult series, it turned into a pop culture touchstone that tapped into public mistrust of governments and large institutions and embraced conspiracy theories and spirituality. Both the series itself and lead actors Duchovny and Anderson received multiple awards and nominations, and by its conclusion the show was the longest-running science fiction series in U.S. television history. The series also spawned a franchise that includes Millennium and The Lone Gunmen spin-offs, two theatrical films, and accompanying merchandise. Premise General The X-Files follows the careers and personal lives of FBI Special Agents Fox Mulder (David Duchovny) and Dana Scully (Gillian Anderson). Mulder is a talented profiler, conspiracy theorist, and strong believer in the supernatural. He is also adamant about the existence of intelligent extraterrestrial life and its presence on Earth. This set of beliefs earns him the nickname "Spooky Mulder" and an assignment to a little-known department that deals with unsolved cases, the X-Files. His belief in the paranormal springs from the claimed abduction of his sister Samantha Mulder by extraterrestrials when Mulder was 12. Her abduction drives Mulder throughout most of the series. Because of this, as well as more nebulous desires for vindication and the revelation of truths kept hidden by human authorities, Mulder struggles to maintain objectivity in his investigations. Special Agent Scully is a foil for Mulder in this regard. As a medical doctor and natural skeptic, Scully approaches cases with complete detachment, even when Mulder, despite his considerable training, loses his objectivity. She is partnered with Mulder initially so that she can debunk Mulder's nonconforming theories, often supplying logical, scientific explanations for the cases' apparently unexplainable phenomena. Although she is frequently able to offer scientific alternatives to Mulder's deductions, she is rarely able to refute them completely. Over the course of the series, she becomes increasingly dissatisfied with her own ability to approach the cases scientifically. After Mulder's abduction at the hands of aliens in the seventh season finale "Requiem", Scully becomes a "reluctant believer" who manages to explain the paranormal with science. Various
