The X-Files

The X-Files is an American science fiction drama television series created by Chris Carter. The original series aired from September 10, 1993, to May 19, 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 single villain, mutant, or monster.
