In the early years of the series, Mulder is a firm believer in extraterrestrials and Scully is skeptical. In real life, this is the opposite, David Duchovny being the skeptic and Gillian Anderson the believer.
The famous echoing chord from the theme music was a fluke. Composer Mark Snow accidentally rested his elbow on his keyboard with the echo function on and he liked the resulting sound so much, he wrote the theme around it.
When casting the role of the Cigarette Smoking Man, the producers had no idea the character would turn into a major role in the series. When the character became more prominent, they worried that William B. Davis, who had only been cast as an extra, would not be able to carry the part. As it turned out, Davis, who is one of the most respected acting teachers in Canada, impressed Series Creator Chris Carter so much that he made the Cigarette Smoking Man the main villain of the series.
Chris Carter wanted the show to end after the fifth season, when his original contract, as well as those of Gillian Anderson and David Duchovny expired. Carter wanted to continue the story in a series of feature films, starting with The X Files (1998). The FOX Network, however, found demand for the show too high to cancel the series, so they instead mandated the film to fit in between series five and six of the show. Carter found writing seasons five and six as well as the film very difficult, as he had to craft a screenplay that would not require the audience to have seen the show to understand it, and episodes of the series that would tie in to the film, but not rely directly on the film's plot to make sense.
During the opening titles, in the Mulder and Scully's F.B.I. ID badges can be read "Federal Bureau of Justice, United States Department of Investigation." This alteration was necessary as making a fake F.B.I. badge, even for fictional purposes, is illegal. The real-life quote is: "Federal Bureau of Investigation, United States Department of Justice."
Props from Mulder's X-Files office are currently preserved and on display at the Hollywood Entertainment Museum in Los Angeles. According to the museum, the famous I Want to Believe UFO poster from the office continually had to be replaced as copies kept disappearing from the set. The poster on display at the museum is reportedly one of the last available copies of the original set-used posters.
Despite their chemistry and the deliberately slow-burning sexual tension of their characters, both David Duchovny and Gillian Anderson have admitted that they were less close and bickered with each other due to the long hours of shooting in Vancouver during the show's initial run. After the show ended in 2002 they increased their natural rapport, and now consider themselves great friends and closer to each other than their spouses.
Gillian Anderson has stated that she based her approach to the role of Dana Scully on Jodie Foster's performance as Clarice Starling in The Silence of the Lambs (1991). Ironically, a contractual obligation to "The X-Files" prohibiting her from playing an F.B.I. Agent in any other role prevented her from being offered the part of Clarice Starling the "Silence" sequel, Hannibal (2001). Later, she joined the Hannibal (2013) series as Bedelia Du Maurier.
In one episode, Scully tells Mulder (David Duchovny) that she thinks Téa Leoni has a crush on him, to which Mulder responds, "How could Téa Leoni have a crush on me?" In real-life, Leoni and Duchovny were married.
Gillian Anderson has declared several times that her favorite episode is "Bad Blood" and David Duchovny that his favorite end in an episode is 'Postmodern Prometheus'', in which Mulder and Scully dance together. Also, they agree that the third season episode "Teso Dos Bichos" is the worst one, with Anderson calling it "that one episode about killer pussycats".
David Duchovny and Gillian Anderson attended the Golden Globes ceremony together in 1997 and were holding hands the whole night. Both of them won best lead actor and actress in a drama series. Anderson could be seen cursing backstage right after picking up her award while watching Duchovny thanking her when he picked up his; she had just realized that she had forgotten to thank him.
Network executives originally wanted a "taller, leggier, blonder, and breastier" actress for the role of Dana Scully. At one point in pre-production of the first season, Pamela Anderson was attached to the role, but Series Creator Chris Carter, who wanted a more cerebral character instead of a more physical one, flatly rejected her. When auditions for the character were finally held, Gillian Anderson was one of the actresses who tested for the part. Carter lobbied for her to be picked, eventually going so far as to talk with her in secret to give her tips on how to get the part., which she was eventually awarded.
Chris Carter lists All the President's Men (1976) as one of his inspirations for the series. There are numerous references to the film, including the shadowy informer Deep Throat, meetings in underground parking garages and hints at conspiracies which stretch all the way to the F.B.I.
The series' Science Consultant, Anne Simon, a virologist at the University of Massachusetts, wrote a non-fiction book in 1999 titled "The Real Science Behind the X-Files: Microbes, Meteorites, and Mutants".
The recurring character Cigarette Smoking Man was never given a name until late in the series. He is referred to as Cancerman in some early episodes. The show's fans took to referring to him as simply CSM.
The series does not show episode titles on-screen. While this was not unusual even in 1993 (though it is more commonplace in 2004 when virtually no American dramatic television series display episode titles), what is unusual is that many fans learned episode titles as well as advance plot information via the Internet. The X-Files (1993) was one of the first television series to be so promoted.
The character Leyla Harrison was named after a writer of The X-Files Internet fan-fiction who died of cancer in February 2001. The fictional Leyla Harrison was a fan of Mulder's and Scully's, having spent her time in the F.B.I. poring over their expense reports (in much the same way that Internet fans of the show examined the minute nuances of every episode).
During the last season of the show, the opening credits included a shot of a list of "F.B.I. Contacts, Witnesses, and Contributors." The names on the list were actually the screen names of posters on the official "X-Files" message board and changed with each new episode that season. Other names on the list were anagrams of characters on the show.
At twenty-nine, Gillian Anderson was the first actress to win an Emmy, a Golden Globe, and a SAG Award in the same year, and the youngest actress to win a Primetime Emmy Award for Outstanding Lead Actress in a Drama Series since Lindsay Wagner won at the age of twenty-eight in 1977 for The Bionic Woman (1976).
Chris Carter has cited Moonlighting (1985) as an influence on this show, specifically the relationship between Mulder and Scully. Carter also has said that the show is an example of how not to further the story, as the sexual tension between the two leads should never be resolved. In spite of this, he always has admitted that Scully loves Mulder and Mulder loves Scully, although he is not very open to a romantic relationship between them being more agree with a platonic love for them.
When Gillian Anderson found out she was pregnant only a few months after the show began and it started to become a huge success, she had told David Duchovny before she told the producers, and they were all extremely supportive, even going so far as to find a story arc that would keep her in the show until shortly before she gave birth. Series Creator Chris Carter would not replace her with another actress. His reward was being named Anderson's daughter's godfather.
The first five seasons of the show were filmed in Vancouver, British Columbia, Canada. The show often cast local Canadian actors in guest and secondary roles, often reusing the same actors in different parts in multiple episodes. The most prominent example of this was Nicholas Lea, who appeared in a guest role in Season One before being cast in the unconnected, more prominent role of Alex Krycek starting in Season Two, but there are many other examples of local actors who had multiple roles over the course of several different episodes, including J.B. Bivens, Lorena Gale, Gillian Barber, Forbes Angus, Larry Musser, Harrison Coe, Hrothgar Mathews, P. Lynn Johnson, and Doug Abrahams (among many others). Each of these appeared in three or more episodes, each time as a different character (Barber played three characters in four episodes).
Several news sources reported that Gillian Anderson was originally offered only half of David Duchovny's salary to return as Dana Scully for season ten. "The Daily Beast" interviewed Anderson about this, and she said, "'I'm surprised that more (interviewers) haven't brought that up because it's the truth". Anderson said of the pay disparity, first disclosed in "The Hollywood Reporter", "Especially in this climate of women talking about the reality of (unequal pay) in this business, I think it's important that it gets heard and voiced. It was shocking to me, given all the work that I had done in the past to get us to be paid fairly. I worked really hard toward that and finally got somewhere with it. Even in interviews in the last few years, people have said to me, 'I can't believe that happened, how did you feel about it, that is insane'. And my response always was, 'That was then, this is now'. And then it happened again! I don't even know what to say about it . . . It is . . . sad . . . It is sad". They eventually received equal pay for the series.
Lucy Lawless' character Shannon McMahon was meant to become a major recurring character in the show's final season. A high-risk pregnancy, however, forced Lawless to leave the show after only two appearances.
Mulder's sister Samantha was abducted while she and Fox were watching an episode of The Magician (1973). When Patricia Hearst was kidnapped by the SLA, she was watching "The Magician" with her boyfriend Steven Weed.
Comedian Kumail Nanjiani (known for shows such as Silicon Valley (2014) and The Meltdown with Jonah and Kumail (2014)), who has a role on the reboot of the series, is also a devoted X-Phile who hosts "The X-Files Files," a podcast on which he discusses and analyzes in detail each episode of the original series. During filming, he was chatting with Gillian Anderson and David Duchovny in a production tent in the middle of the night when they asked why he wasn't recording the conversation for his podcast--so he did. At their urging, he asked them about which episodes of the show they thought were the worst. Anderson listed "Space," "Fire," the episode she first called "The Cat One--Los Lobos Tostitos" before Duchovny "corrected" her and said "Tesos Tostados" and Nanjiani provided the actual name of that episode, "Teso dos Bichos." Duchovny identified "the chupacabra episode" ("El Mundo Gira") as one of his worst.
Although David Duchovny had been asked many times to have Gillian Anderson guest-star in an episode of his series Californication (2007), he has said that he would never do that because he wanted to preserve their special relationship as Mulder and Scully.
Mulder saw Edward D. Wood, Jr.'s Plan 9 from Outer Space (1959) 42 times. He also lives in apartment number 42. 42 is the answer to life, the universe, and everything from Douglas Adams's "The Hitchhiker's Guide to the Galaxy", another cult science fiction story.
David Duchovny and Gillian Anderson have often stated that they share a close and personal link because they are the only two people in the world who have felt and lived the special, unique and intimate relationship between Mulder and Scully and the worldwide phenomenon that the series became.
The younger son of Gillian Anderson is named Felix, which contains exactly the same letters as "X File". She got pregnant during the filming of the second movie. Her daughter, Piper Anderson-Klotz, has an episode named after her.
Robert Patrick, who played Special Agent John Doggett, is the brother of Richard Patrick, the lead singer of Filter. Filter's music has appeared on the television soundtrack, "Songs in the Key of X", and the The X Files (1998) movie soundtrack.
Recurring use of the numbers: 1013 - Ten Thirteen is the name of Chris Carter's production company; his birthday is October 13, 1956. 1013 is also the silo number that Alex Krycek is locked into in season three, and 10:13 is the time where start some episodes (or a scene that's dated at this time). The number 1121 also appears often; it is creator Chris Carter's wife, Dori's, birthday.
Every time Skinner goes to Mulder's apartment, someone pulls a gun on him: 1). In season two, episode seventeen, The X-Files: End Game (1995), Mulder aims a gun after Skinner enters the apartment, suspecting him to be the Bounty Hunter. 2). Later in the same episode, minutes before entering the apartment, he gets in a fist fight with X in the elevator, ending with X pulling out a gun. 3). The season three premiere, The X-Files: The Blessing Way (1995), ends with Scully bringing Skinner to the apartment where she pulls her gun on him, believing he intended to kill her. 4). Season three, episode nine, The X-Files: Nisei (1995), features a scene where Mulder unexpectedly finds Skinner in his ransacked apartment, and draws his gun. 5). In season six, episode twenty-one, The X-Files: Field Trip (1999), Scully has a spore-induced dream in which Skinner and other friends are in Mulder's apartment for Mulder's funeral. Later in the episode, Mulder shoots the dream-Skinner to prove that they are still dreaming. This is the only episode where the gun being drawn occurs outside of Mulder's apartment building, but both scenes are part of a hallucination. Nevertheless, the sole exception is the season five premiere, The X-Files: Redux (1997), in which Skinner confronts Scully in the hallway outside Mulder's apartment early in the episode. However, Skinner is not shown to have actually entered the apartment in the episode, just the hallway. Other exceptions: In season six, episode eleven "Two Fathers", Skinner meets covertly with Mulder and Scully inside Mulder's apartment, where they fill him in on the alien hybrid plan and divulge who Spender's father is. In season seven, episode ten "Sein und Zeit", Skinner knocks at Mulder's apartment the morning after Mulder has a breakdown over his mother, and Scully answers the door, having been there all night to comfort him. The scene shows all three in the doorway, though Skinner is not shown entering the apartment.
When some important character was going to die, Chris Carter used to include in his/her script copy one note saying "Nobody dies in The X Files". In fact, he kept his word many times, returning these characters in special apparitions.
Mitch Pileggi, who had a semi-regular role as Skinner, would later get a recurring role on Supernatural (2005) as Sam and Dean's grandfather, Samuel Winchester. "Supernatural" is often referred to as an "X-Files" clone.
Mulder graduated Cum Laude from Oxford University (psychology) and was the first one of his class at the F.B.I. Academy in Quantico, Virginia. Scully studied physics and medicine, but was recruited by the F.B.I. She chose to become an F.B.I. Agent rather than a medical doctor.
In the UK Twentieth Century Fox Home Entertainment released new "Mytharc" multi-part episodes as edited-together television movies on VHS in the mid 1990s. However, these tapes (which usually took the title of just one of the episodes comprising them but were sometimes completely re-named) were extremely expensive and released as numbered "Files" in the wrong order. For example "File 3: Abduction" ("Duane Barry"/"Ascension"/"One Beath") confusingly came after "File 1: The Unopened File" ("Anasazi"/"The Blessing Way"/"Paper Clip"). Although by the third season most mythology episodes were multi-part stories, important plot information relating to the conspiracy could still sometimes only be found in the unavailable standalone episodes to further confuse viewers of these releases. Also, "Colony"/"Endgame" and "Piper Maru"/"Apocrypha" were seemingly forgotten to be included in the series until long after many later episodes.
The addition of the Skinner character in The X-Files: Tooms (1994) was fortuitous for Mitch Pileggi, as the part was to go to the actor who played Blevings but who was busy when this episode was to be shot, and it was given to Pileggi instead. His chemistry with Mulder, Scully, and CSM resulted in Skinner being made a permanent member of the cast of characters.
Many of the cast's real-life partners worked on the show: Perrey Reeves, David Duchovny's girlfriend for two years, played his lover in "3". Maggie Wheeler and Lucy Liu, both of whom dated Duchovny, appeared in "Born Again" and "Hell's Money", respectively. Even his former wife, Téa Leoni, played herself in "Hollywood A.D." Gillian Anderson dated Rodney Rowland, who appeared in "Never Again", for over a year. She also dated Adrian Hughes, who played one of the Peacocks in "Home". She was married to, and had a daughter with, Clyde Klotz, the show's Art Director, after they met at the beginning of the series. Mitch Pileggi met his wife, Arlene Pilleggi, on the set of the show--she played his secretary and was Gillian Anderson's double. Robert Patrick's wife played his character John Doggett's wife in the final season.
Although the Cigarette Smoking Man is obviously famous for chain smoking cigarettes, he only utters the word "cigarette" one time during the show's run. William B. Davis, who plays him, was a former smoker who had not smoked since 1973, twenty years before he was cast for the series. At the beginning of the show the cigarettes he smoked were real, until he became aware that he was having cravings for tobacco when not filming. At his request, the cigarettes used from then on were herbal.
According to Gillian Anderson, at the beggining of the series, she was supposed to walk one or two steps behind Mulder in order to give him the prominence. She clearly won her own position in a few episodes.
Over the years, The Scully Effect, that consists in how young women have chosen to join to law enforcement and medicine as a result of their admiration for the inner strength of Scully, has grown all over the world.
When Agents Miller and Einstein are first introduced in the tenth season, there are several jokes and references that indicate that they are meant to be analogues of Mulder and Scully's younger selves, including Miller's credulity in contrast with Einstein's skepticism and Einstein's red hair and science-related name. The name "Miller" is also a clue to this; the last name "Mulder" originally comes from a Dutch word that means "miller" (that is, a person who runs a grain-processing mill).
In a 2015 interview with National Public Radio, Composer Mark Snow said that when he was originally trying to compose the theme song, after he sent Series Creator Chris Carter a few ideas, which Carter rejected, Carter sent Snow the 1985 song "How Soon Is Now?" by The Smiths, saying, "I just love these guitars. Listen to this song, and see if it inspires something." Snow also said that he got the idea for the whistling element of the theme from an old Proteus sample called "Whistling Joe", but the whistle actually heard in the recording of the theme is bolstered by Snow's wife, who was a particularly strong whistler.
Often, throughout the series, Mulder asks for help from three conspiracy theorists named Byers, Langley and Frohike. They call themselves "The Lone Gunmen" and print a conspiracy paper of the same name. This is a nod to their disbelief in the "Lone Gunman" theory, which is the official explanation of the assassination of President John F. Kennedy, which states that Lee Harvey Oswald was the only one involved in the assassination only he fired the shots that killed Kennedy.
One of the first television series to switch to a 16:9 widescreen aspect ratio, beginning with its fifth season in 1997 at the insistence of Chris Carter to give the show a more cinematic feel, though FOX aired the episodes cropped to 4:3 while the original 16:9 versions were released on DVD. The series was remastered in 16:9 high definition in 2014, converting the first four seasons to widescreen as well, generally through cropping.
Piper, Gillian Anderson's daughter, was literally raised on the set of this show, so when she saw a monster or something that would scare any other child she used to be curious and ask if she could touch it. Regarding this situation, David Duchovny used to say he was lucky for not being the one who would have to pay for her therapist. On the contrary, when Gillian wanted to her younger sons see her in the series she showed them Bad Blood, one of the most comic episodes, it only gave them nightmares.
Former Director and Producer Rob Bowman didn't return to direct the series, because in a roundtable discussion as to whether or not to do another "X-Files" feature film, it was decided that a six-episode mini-series would be able to go more in depth with previous story arcs and continuity from the original series and first film.
In keeping with the original series run's practice of reusing Canadian character actors in multiple unrelated parts, Hiro Kanagawa, Christine Willes, and Alex Diakun each appeared in one of the three first episodes of the long-delayed tenth season aired in 2016. Kanagawa played two different characters in the second and fourth seasons; Wiles had the small but recurring role of F.B.I. Agent Karen E. Kosseff (Scully's therapist) in three different episodes; and Diakun played four different characters in the second and third seasons and the second movie.
Duchovny: "Celebrating twenty-five years, makes me look back when I first met Gillian. It was during the casting, I was looking for some matches and she took them out and approached me, just like that, without saying a word."
The opening credits of the series are among the most famous in television history, but they actually hadn't changed much over the twenty plus years since the pilot aired, except for the two years after David Duchovny left the show and the long-awaited addition of Mitch Pileggi.
David Duchovny textually declared "I never, ever, ever cook. And I would never eat something I might cook". Mulder seems to have similar abilities since we have never seen him cooking, he usually eats fast food and the few times we saw him in his kitchen his fridge was almost empty or his food is expired.
The red speedo that Mulder wears in his scene with Krycek at the beginning of the episode became a sexual icon, so, many years after that, it still is the object of multiple jokes of the fans and the crew, particularly his partner. Anderson, among other things spoke about his size or was photographed dressed with other red speedo on a couch. Darin Morgan also wrote a gag in the tenth season so Mulder could wear it again and he was admired for it by a special character.
In the The X-Files: Pilot (1993), when Scully is interviewed by Division Chief Scott Blevins (Charles Cioffi) to see if she knows Fox Mulder, she replies that she didn't know him directly, but by his reputation as the F.B.I.'s analyst and his work in the capture in 1988 of a killer named Monty Props. It's the only reference about Props made in the entire series. Props was created after Garret Jacob Hobbs, a serial killer only mentioned in Thomas Harris' novel "Red Dragon" (who was shot to death by Will Graham). Harris' universe was a strong influence in the creation of the series.
Among the most famous clichés in the tons of fanfics written since the series started are: Scully is known as Ice Queen in the F.B.I. Mulder has oral fixation. There is a poll in the F.B.I. regarding when Mulder and Scully will consummate their relationship. Mulder and Scully always have a connection door between their rooms in the motels. Mulder and Scully are forced to share a bed. Charlie, Scully's little brother, is a nice guy. Skinner always knew about Mulder and Scully secret romantic relationship.
Regarding Scully's wardrobe in the first seasons, according to Gillian Anderson, nobody paid attention to her then. However, she has been much more involved in this aspect of her character in the revival seasons.
There are sixty-nine alien mythology episodes in the series. Season eight has the biggest amount, with ten of them coming from there. Only two episodes in season eight involving Mulder didn't focus on the mythology arc. There are also other episodes about extraterrestrials and alien abductions unrelated to the arc, such as Conduit and Clyde Bruckman's Final Repose.
Most of the fans want the relationship between Mulder and Scully and they are named shippers and most recently Sculder, as noromo are the fans that don't want their romance. After the fans of this show started using the term "shipper", this term was used in other fandoms. In the same way, fans that believe in a romance between Duchovny and Anderson are named snoggers or Gillovny.
Both hallways and bathrooms are mythological places in the series but in different ways. Mulder and Scully have had some of their most romantic moments in hallways and different characters had suffered hard moments in the bathrooms.
This show is the big germination of Breaking Bad (2008). Vince Gilligan not only exploded here as a fantastic writer, becoming in one of the favorite series of both the audience and the critics, found here his most relevant collaborators, but also presented the basic characteristics of Walter White in characters like Robert Modell.
The tenth season mixes its own mythology with "Monster of the Week" episodes, being just the first and last episode of the season dedicated to the mythology, and the other four to the Monster of the Week.
Gillian Anderson on her chemistry with Duchovny: "For whatever reason, there is this energy between us when we come together, which is very compelling and curious. Why do we have that? There's attraction on screen with other actors I have worked with, but it's not the same. What's different between David and me? I don't know."
Duchovny on his chemistry with Anderson: "The chemistry is completely easy; it is something that we seem to be able to slip into with our eyes closed. From the second we started working together, it was there. There's a lot of déjà vu."
It was supposed to be, that only men were to be in the writer's room in the eleventh season, but after some voices praying for more women participants in the production, lead by Gillian Anderson, two female directors and three writers were hired.
Almost all of David Duchovny and Gillian Anderson's children worked on the show. Piper, Gillian's daughter, worked in the Art Department in seasons ten and eleven. Her little brothers, Oscar and Felix, worked as extras in This, also in the eleventh season. We can see them on the bus in which Mulder and Scully travel. West Duchovny had a small, but important part in the last episode of the eleventh season, but David's younger kid, Miller, never acted on the show.
The trivia items below may give away important plot points.
Scully's abduction during the second season was originally planned as a way of explaining Gillian Anderson's absence due to pregnancy. Later, Series Creator Chris Carter turned it into a vital plot point to the on-going series mythology for the original run of the series until 2002 as well as in the revival of 2015 to 2016.
At the conclusion of Season Seven, David Duchovny and Gillian Anderson had yet to be signed for extra seasons, and most of the cast and crew assumed the show would end. Chris Carter wrote the episode "Requiem" to function as a series finale, at the last minute the FOX Network decided to renew the show. Only Anderson agreed to return to the show full-time, though, and Carter created the characters of John Doggett (Robert Patrick) and Monica Reyes (Annabeth Gish) to compensate for Duchovny's absence. Carter also retooled the series mythology to focus on government Super Soldiers, and to eliminate plot threads regarding the alien invasion conspiracy with the hopes that it would revive interest in the show.
According to Chris Carter, the exact moment when Mulder first fell for Scully was the moment she walked in his door in the pilot and the first time she did it was when he phoned her when she is on her bed in this first episode.
Piper Anderson-Klotz, Gillian Anderson's daughter, was working in the Art Department during the production of seasons ten and eleven. Piper was born during the second season of the series and her unexpected birth was the reason the show's writers devised Scully's abduction, which went on to become one of the most important mythological arcs in the original series. The third season episode The X-Files: Piper Maru (1996) was also named after her.
The Lone Gunmen (Bruce Harwood, Tom Braidwood, and Dean Haglund) from the original series were contacted about the possibility of appearing in an episode of the tenth season. Eventually they made a silent cameo dressed like cowboys as part of a hallucination after Mulder ate special mushrooms in order to induce himself into a trance to connect mentally with a patient in coma (season ten, episode five).
In a piece of self-referential production design, the opening title designs for season ten revert to the original legacy (pre-Doggett and Reyes) wide-screen cropped version of the original Mulder and Scully title design.
When she returned to playing Scully for season ten, Gillian Anderson opted to wear a wig instead of dying her hair red, because it would most likely cause her hair to fall out due to having it dye back to blonde immediately (for her role on The Fall (2013)) after the shooting of the revival wrapped.
In The X-Files: Mulder & Scully Meet the Were-Monster (2016) (season ten, episode three), Scully jokes with Mulder that she's immortal. Nevertheless, it isn't a joke. In The X-Files: Clyde Bruckman's Final Repose (1995) (season three, episode four), Mulder and Scully meet Clyde Burckman (Peter Boyle), a life insurance salesman who, after rock star Buddy Holly's death in an airplane crash in 1959, became so obsessed with the death that he acquires the ability to see when everybody going to die. At one point, Scully questions Bruckman about her death, and he simply answers "You don't". Eventually, in The X-Files: Tithonus (1999) (season six, episode ten), Scully meets Alfred Fellig (Geoffrey Lewis), a freelance crime photographer who is one hundred forty-nine-years-old and turned into an immortal decades before when he was dying in a hospital. Felling saw Death directly go for him, but he rejected her, asking that another die instead of him. Death killed a nurse who assisted him, and Fellig lived looking for Death in order to die, being capable of knowing when a person will die and photographing the corpse trying to capture Death in a photo. At the end of the episode, Scully and Fellig are shot by an assassin wanted by Mulder and Scully. She sees Death go for her, and Fellig asks her to turn around her head to avoid dying. Fellig dies, but Scully recovers completely in the hospital, effectively taking on Fellig's immortality. Scully's immortality also appears in The X-Files: My Struggle II (2016) (season ten, episode six), after she finds that she is immune to a lethal plague that is isolating the world.
Given the excessive length of Mulder and Scully's unresolved sexual tension and the way in which it was suggested and resolved, many fans called season seven "the season of the secret sex". Later, in season ten, some clues seemed to insinuate that Mulder and Scully could have been married at some previous point. David Duchovny referred several times to Scully as Mulder's "wife", and there were some pictures in which Scully seemed to wear a ring. Because of this, many fans refers to season ten as "the season of the secret marriage". Chris Carter later denied they were married, and Gillian Anderson told Duchovny that "they only lived in sin" and she "thought they were smoking a joint, lying in bed" but not "married married".
So far at the end of the tenth season, more than twenty-three years after the beginning of the series, never have been revealed how and when Mulder and Scully became lovers. This is probably the most exaggerated effort ever in a series for maintaining the UST between its characters. There are many theories in the fandom but it's sure that they were already lovers at the end of season seven, in which Scully dresses in Mulder's bedroom while he's sleeping naked and a few episodes later she becomes pregnant with their child, even the first time somebody speaks about it explicitly is in Trustno1 (ninth season).
The series is divided in two separated lines. The first is called "Mythology", and the second "Monster of the Week". Both never cross between them, even all mention about one in other is omitted, almost as if it would to alternate timelines. The main plot of these arguments is: -Mythology: It's a conspiracy where an alien race known as "The Gray" plans to invade planet Earth using the called Black Oil or "Purity" (a living virus that after to infect a human body, turning us in living incubators, grow up inside it to be a Gray, killing bloodily to the host in the birth). These race made a treat with a few human group called The Syndicate, composed by former scientists and doctors from the World War II, some of them implicated in the Operation Paperclip (U.S.'s Government pardoned crime wars to captured Third Reich's scientists to continue their work in medicine, science, and astronautic), working secretly to experiment with humans looking for a cure of the Black Oil, in a try to be saved of the invasion. The Syndicate would use the smallpox's vaccine to create an DNA's catalog for their experiments, inserting at the same time alien's DNA as a weapon to be used in the invasion. The Gray and The Syndicate are faced with another alien race simply known as the Resistance, a humanoid species that they have the ability to change their physical shape, and that they sewn themselves eyes, mouth and ears to avoid any possibility to be infected by the Black Oil. -Monster of the Week: an auto-concluded episode where are depicted all kind of supernatural phenomenons, since evil experiments, telepathy and mind control to angels and demons, reincarnation, ghosts, and strange creatures as vampires, were-wolfs and mutants. Sometimes these episodes have open ending, leaving a chance to be continued more later, meanwhile others end dramatically, closing the plot for not be continued.
Chris Carter stated that the X-Files weren't closed, since the F.B.I. had discovered the hybrid race invasion would happen in 2012. Allegedly, the timeline takes place after the invasion had already begun. This creates a "backwards"-envisioned storyline told in the present tense that watches what may have happened during the time lapse.
CSM ends being Mulder's biological father, but we never really know how and when Mulder finds out. He has suspected it at least twice since the fourth season; in fact, the only time we see CSM telling him is in "Amor Fati" and in a conversation that happens in Mulder's dream. Spender also affirms it in the same episode. Scully seems to be sure of this after season six, because it's confirmed by Scully, in "William" after doing DNA tests on Jeffrey Spender, that Mulder is Spender's half-brother, and it's established that Mulder is CSM's son in "The Truth".
Mulder, Scully, or both of them has been in every continent of the Earth but Oceania in the first ten seasons of the series or the movies, including Antarctica, where Mulder went to in the first movie in order to save Scully.
In The X-Files: Shapes (1994) (season one, episode nineteen), Mulder and Scully travel to Montana to investigate a possible werewolf. At the end of the episode, an old Native American man named Ish (Jimmy Herman) says to the pair, "See you in about . . . eight years" in the belief that the werewolf's curse repeats every eight years. Since this episode aired in 1994, eight years later would be in the series' ninth season, when Mulder is hidden.
In The X-Files: Re-Opened (2015), the documentary before season ten, Chris Carter describes Mulder's and Scully's relationship as "platonic" for nine years, even though there was an obvious attraction between them, were together on the run, lived together for years as lovers and had a child together.
Mulder was born in Chillmark, Massachusetts, to Bill Mulder, who worked for the U.S. State Department in different secret projects, and his wife Teena. As it turned out, Bill wasn't actually his real father, but that's not revealed until season seven. Dana Scully is the third of four children of Captain Bill Scully and his wife, Maggie. Because of his job, the family travelled all over the world during their childhood.
