The X-Files

The X-Files is an American science fiction drama television series created by Chris Carter. The original series aired from September 1993 to May 2002 on Fox, spanning nine seasons, with 202 episodes. A tenth season of six episodes ran from January to February 2016. Following the ratings success of this revival, The X-Files returned for an eleventh season of ten episodes, which ran from January to March 2018. In addition to the television series, two feature films have been released: the 1998 film The X-Files and the stand-alone film The X-Files: I Want to Believe, released in 2008, six years after the original television run ended.

The series revolves around Federal Bureau of Investigation (FBI) Special Agents Fox Mulder (David Duchovny) and Dana Scully (Gillian Anderson), who investigate the eponymous "X-Files": marginalized, unsolved cases involving paranormal phenomena. Mulder is a skilled criminal profiler, an ardent supernaturalist, and a conspiracy theorist who believes in the existence of the paranormal, whereas Scully is a medical doctor and skeptic who has been assigned to scientifically analyze Mulder's case files. Early in the series, both agents apparently become pawns in a much larger conflict and come to trust only each other and select others. The agents discover what appears to be a governmental agenda to hide evidence of extraterrestrial life. Mulder and Scully's shared adventures initially lead them to develop a close platonic bond, which develops into a complex romantic relationship. Roughly one third of the series' episodes follow a complicated mythopoeia-driven story arc about a planned alien invasion, whereas the other two-thirds may be described as "monster of the week" episodes that focus on a singular villain, mutant, or monster.

The X-Files was inspired by earlier television series featuring elements of suspense, horror, and speculative science fiction, including The Twilight Zone, Night Gallery, Tales from the Darkside, Twin Peaks, and especially Kolchak: The Night Stalker. When creating the main characters, Carter sought to reverse gender stereotypes by making Mulder a believer and Scully a skeptic. The first seven seasons featured Duchovny and Anderson relatively equally. In the eighth and ninth seasons, Anderson took precedence while Duchovny appeared intermittently. New main characters were introduced: FBI Special Agents John Doggett (Robert Patrick) and Monica Reyes (Annabeth Gish), among others. Mulder and Scully's immediate superior, Assistant Director Walter Skinner (Mitch Pileggi), began to appear regularly. The first five seasons of The X-Files were filmed in Vancouver, British Columbia, before production eventually moved to Los Angeles, apparently to accommodate Duchovny's schedule. However, the series later returned to Vancouver with the filming of The X-Files: I Want to Believe as well as the tenth and eleventh seasons.

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 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 American television history. The series also spawned a franchise that includes Millennium and The Lone Gunmen spin-offs, two theatrical films, and accompanying merchandise.

The X-Files follows Federal Bureau of Investigation (FBI) Special Agents Fox Mulder (David Duchovny) and Dana Scully (Gillian Anderson). Special Agent Mulder is a talented profiler, conspiracy theorist, and an ardent supernaturalist. He is also adamant about the existence of intelligent extraterrestrial life and its presence on Earth. These beliefs earn 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 alien abduction of his sister Samantha Mulder 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 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 explains the paranormal with science.

Various episodes also deal with the relationship between Mulder and Scully, originally platonic, but that later develops romantically. Mulder and Scully are joined by John Doggett (Robert Patrick) and Monica Reyes (Annabeth Gish) late in the series, after Mulder is abducted. Doggett replaces him as Scully's partner and helps her search for him, later involving Reyes, of whom Doggett had professional knowledge. The initial run of The X-Files ends when Mulder is secretly subjected to a military tribunal for breaking into the top-secret Mount Weather Emergency Operations Center and viewing plans for alien invasion and colonization of Earth. He is found guilty and sentenced to death but escapes punishment with the help of the other agents, and he and Scully become fugitives.

Key episodes called parts of the "Mytharc", were recognized as the "mythology" of the series canon; these episodes carried the extraterrestrial/conspiracy storyline that evolved throughout the series. "Monster of the week"—often abbreviated as "MOTW" or "MoW"—came to denote the remainder of The X-Files episodes. These episodes, forming the majority of the series, dealt with paranormal (and in certain cases, merely criminal) phenomena, including: serial killers (with or without supernatural powers), cryptids, ghosts, mutants, science fiction technology, horror monsters and religious phenomena. Some of the Monster-of-the-Week episodes featured satiric elements and comedic story lines. The main story arc involves the agents' efforts to uncover a government conspiracy that covers up the existence of extraterrestrials and their sinister collaboration with said government. Mysterious men constituting a shadow element within the U.S. government, known as "The Syndicate", are the major villains in the series; late in the series it is revealed that The Syndicate acts as the only liaison between mankind and a group of extraterrestrials that intends to destroy humanity. They are usually represented by Cigarette Smoking Man (William B. Davis), a ruthless killer, masterful politician, negotiator, failed novelist, and the series' principal antagonist.

As the series goes along, Mulder and Scully learn about evidence of the alien invasion piece by piece. It is revealed that the extraterrestrials plan on using a sentient virus, known as the black oil (also known as "Purity"), to infect mankind and turn the population of the world into a slave race. The Syndicate—having made a deal to be spared by the aliens—have been working to develop an alien-human hybrid that will be able to withstand the effects of the black oil. The group has also been secretly working on a vaccine to overcome the black oil; this vaccine is revealed in the latter parts of season five, as well as the 1998 film. Counter to the alien colonization effort, another faction of aliens, the faceless rebels, are working to stop alien colonization. Eventually, in the season six episodes "Two Fathers"/"One Son", the rebels manage to destroy the Syndicate. The colonists, now without human liaisons, dispatch the "Super Soldiers": beings that resemble humans, but are biologically alien. In the latter parts of season eight, and the whole of season nine, the Super Soldiers manage to replace key individuals in the government, forcing Mulder and Scully to go into hiding.

California native Chris Carter was given the opportunity to produce new shows for the Fox network in the early 1990s. Carter was tired of the comedies he had been working on for Walt Disney Pictures. A report that said 3.7 million Americans believed they may have been abducted by aliens, the Watergate scandal, and the 1970s horror series Kolchak: The Night Stalker all contributed to trigger the idea for The X-Files. He wrote the pilot episode in 1992.

Carter's initial pitch for The X-Files was rejected by Fox executives. He fleshed out the concept and returned a few weeks later, whereupon they commissioned the pilot. Carter worked with NYPD Blue producer Daniel Sackheim to further develop the pilot, drawing stylistic inspiration from the 1988 documentary The Thin Blue Line and the British television series Prime Suspect. Inspiration also came from Carter's memories of The Twilight Zone as well as from The Silence of the Lambs, which provided the impetus for framing the series around agents from the FBI, to provide the characters with a more plausible reason for being involved in each case than Carter believed was present in Kolchak. Carter was determined to keep the relationship between the two leads strictly platonic, basing their interactions on the characters of Emma Peel and John Steed in The Avengers series.
