Julie Gardner has said that when David Tennant was approached to play the Tenth Doctor, he was immediately enthusiastic. His first response was to ask, "Can I have a long swishy coat?"

Matt Smith actually owned the tweed jacket his Eleventh Doctor usually wore.

When the first season was being made, television pirates were desperate to acquire the preview tapes. One of the people in the office had the idea of labelling the tapes with the anagram "Torchwood", rather than "Doctor Who", as a security measure to disguise the tapes when they were delivered from Cardiff to London. Writer Russell T. Davies liked this idea so much, that it later inspired him to use it as a title when creating the spin-off series, Torchwood (2006).

Writer and Executive Producer Russell T. Davies had Christopher Eccleston's name on a shortlist for the role of the Doctor, but didn't really think that he would accept the role because of his reputation as a very serious actor with a background in hard-hitting dramas. However, Eccleston was such a big fan of Davies as a writer that he got in contact to ask if he could audition for the part. Eccleston had not been a fan of the original series, so he watched Doctor Who: The Talons of Weng-Chiang: Part One (1977), one of the most popular serials from the original run and a particular favorite of Davies's for the quality of its dialogue, as part of his preparation.

When Peter Capaldi was chosen as the Twelfth Doctor, he became the first Oscar winner to play The Doctor (though not for acting), and the third Scottish actor (after Sylvester McCoy and David Tennant).

Fifth Doctor Peter Davison has said he considers this series an improvement on the original, not only because of its budget and digital effects, but also because the series is produced by a writer, unlike the original series, which was always produced by a BBC staff producer who was assisted by a script editor. Davison has said that Rose, played by Billie Piper, was the first properly developed companion in the history of the series, and he expressed admiration for the sexual "frisson" and "tension" which was previously disallowed between the Doctor and his companions. He said he was "rather envious" of the French kissing the new Doctors got to do because his producer, John Nathan-Turner, had considered it inappropriate for the Fifth Doctor to even put his arms around his female companions in case viewers thought there was something sexual going on. Davison has also said he prefers the orchestral musical compositions by Murray Gold to the electronic incidental music produced by the Radiophonic Workshop during his time on the series.

Peter Capaldi had appeared on the show in a different role, before being cast as the Twelfth Doctor, but Colin Baker did too in the original, so this is not the first time an actor playing the Doctor, had previously appeared as a different character on the show. Coincidentally, Capaldi appeared in the episode in which Karen Gillan had a different role, before being cast as a full-fledged companion, Doctor Who: The Fires of Pompeii (2008).

Georgia Moffett asked her son Tyler who his favorite Doctor was. Tyler named David Tennant, because he runs so fast. When Moffett married Tennant, he adopted her son, and his name was changed from Tyler Moffett to Tyler Tennant.

Except for obvious scenes, most of the location shots are done in Cardiff, Wales in place of London. The one episode set in Cardiff, Doctor Who: The Unquiet Dead (2005), was filmed in Swansea, mainly due to the fact that no buildings currently in Cardiff were built during that episode's time, 1869. Aside from this, Cardiff is the home of "Torchwood 3", which is featured in the episode "Last of the Time Lords".

Russell T. Davies did not audition any actors for the role of the Tenth Doctor, as he had recently finished working with David Tennant, and believed him to be perfect for the role. Tennant was first approached about the possibility of playing the Tenth Doctor at a screening of Doctor Who: Rose (2005) at Davies' house on March 23, 2005. Contrary to fan-invented belief, Tennant was never considered for the role of the Ninth Doctor.

According to a report in the Radio Times in 2014, the Twelfth Doctor's white button-down shirt was added to the long black coat and Dr. Martens look as a tribute to rock star and style icon David Bowie's "Station to Station" album cover from 1976.

At first, the estate of the late Terry Nation refused permission for them to use Daleks in the show (Nation held copyright over the Daleks as the man who wrote the first Dalek serial). One of the reasons they refused permission, was because of the BBC granting permission for the Daleks to be used in Looney Tunes: Back in Action (2003).

The T.A.R.D.I.S. prop used for the first season, with Christopher Eccleston, was put up for auction by Bonhams of London in 2010, and sold for ten thousand eight hundred pounds.

Each forty-five minute episode takes approximately three weeks to shoot. The hour long specials can take up to a month to shoot.

On Thursday, March 31, 2005, the day after the show was picked up for a second season, the BBC Press Office announced that Christopher Eccleston was quitting the show, citing a fear of being typecast, and long working hours as reasons for his departure. The BBC later apologized for issuing this statement, as they had done so without consultation with Eccleston. In fact, it was agreed by mutual consent several months earlier, that Eccleston would only do one season, with the BBC holding off announcing the news until after the season was finished. This would have allowed the regeneration of Eccleston's Ninth Doctor in episode thirteen to be a surprise for the audience. Unfortunately, the BBC Press Office jumped the gun under pressure from the British Press, who were concerned that a second season had been announced, but it had not been confirmed that Eccleston was returning. Fan reaction to Eccelston's departure was violent, and the debate reached such a fever pitch, that Outpost Gallifrey, the biggest Doctor Who fan site on the Internet, was forced to close down its forum for several days.

For the first season, producers were fearful of alienating new audiences with references to the original show, such as names and events, so such things were kept to a bare minimum until audiences adjusted to the mythology. Even the first journey to another planet beyond Earth didn't take place until season two, which is unusual, considering the universe-trotting nature of the original series.

A potential spin-off, "Rose Tyler: Earth Defence", was proposed in 2006, but did not progress beyond the idea stage, partly because Billie Piper did not want to return to the role, partly because Russell T. Davies realized that it would render the goodbye between The Doctor and Rose at the end of season two meaningless.

Peter Davison (The Fifth Doctor), Elisabeth Sladen (Sarah Jane Smith), John Leeson (K-9), Tom Baker (The Fourth Doctor), Paul McGann (The Eighth Doctor), and Ysanne Churchman (Alpha Centauri) are the only cast members to play the same character in both Doctor Who (1963) and Doctor Who (2005).

Hugh Grant was once approached to play the Doctor. He turned down the role, thinking the show would not take off. He expressed deep regret in 2007, after seeing how successful the show had become. He had played the Doctor in Comic Relief: Doctor Who - The Curse of Fatal Death (1999).

Russell T. Davies originally wanted Kate Winslet to play River Song.

Actors and actresses considered for the role of the Eleventh Doctor included James Nesbitt, Robert Carlyle, Bill Nighy (who said in 2013 it "comes with too much baggage" for him), David Walliams (who also expressed interest and came extremely close to being cast, but conflicts with Little Britain USA (2008) forced him to turn it down), Harry Lloyd, David Morrissey, Paterson Joseph, David Knijnenburg, Daniel Radcliffe, Catherine Zeta-Jones, John Simm, Russell Tovey, Sean Pertwee, Russell Crowe, and Randy Orton.

To celebrate the 50th Anniversary special, and to combat his disappointment at not being given a role in it, Peter Davison made his own amateur webisode anniversary special The Five(ish) Doctors Reboot (2013). The short webisode (which Davison wrote and directed, and his daughter produced) starred his friends and relatives, with many former Doctor Who (1963) cast members making cameo appearances. The plot revolves around Davison, Colin Baker, and Sylvester McCoy trying to sneak into the set of the 50th Anniversary special, when Steven Moffat declines to cast them.

On Saturday, March 5, 2005 (three weeks before its television debut), a rough-cut version of Doctor Who: Rose (2005) was leaked onto the Internet by an unnamed employee of a third-party contractor to CBC in Canada. The person responsible had their employment immediately terminated. The version is mostly similar to the broadcast version, the most notable difference is that instead of using Murray Gold's new version of the theme song, a remixed version of the original was used instead.

The production schedule required Matt Smith to work twelve hour days for ten months of the year.

Russell T. Davies named Rose Tyler and Captain Jack Harkness after Rose DeWitt Bukater and Jack Dawson, the main protagonists of James Cameron's Titanic (1997), played by Leonardo DiCaprio and Kate Winslet, respectively. Kate Winslet had worked with Russell T. Davies on Dark Season (1991), and was the original choice for River Song.

In 2016, the series' star Peter Capaldi accused the BBC of neglecting it with inconsistent scheduling.

Freema Agyeman (Martha Jones), John Barrowman (Captain Jack Harkness), Naoko Mori (Toshiko Sato), Eve Myles (Gwen Cooper), Gareth David-Lloyd (Ianto Jones), Lachele Carl (Trinity Wells) and Anthony Debaeck (French newsreader) are the only cast members to play the same character in this show and Torchwood (2006). Of these, only Carl and Debaeck also played the same character in The Sarah Jane Adventures (2007).

The T.A.R.D.I.S. set for the Ninth Doctor took eight weeks to build.

Less than a week before season nine started, it was confirmed, it would be Jenna Coleman's last season.

This series is a direct continuation of the 1963-1989 series, rather than a reboot, reimagining or "next generation" style follow-up. The BBC decided to reset the series numbering at one for 2005, rather than call it season twenty-seven,. However, fans informally refer to the seasons by the higher number.

When Steven Moffat took over from Russell T. Davies as the showrunner, he wanted the series to be told from Amy Pond's point of view, and wanted the series to be like a fairy tale. Amy Pond goes with her imaginary childhood friend The Doctor, whom she nicknames The Raggedy Man, and goes with him in his magic police box "The T.A.R.D.I.S." on a magical adventure across time and space.

Several episodes begin with the same sequence: a view of the Earth's moon, then panning towards Earth, followed by a fast zoom down to London. Episodes, in which this opening was used, include Doctor Who: Rose (2005), Doctor Who: The Christmas Invasion (2005), Doctor Who: Army of Ghosts (2006), and Doctor Who: The Runaway Bride (2006).

Recurring characters Captain Jack Harkness and Dr. River Song are played by an actor and actress who share March 11th birthdays: John Barrowman, born in 1967, and Alex Kingston, born in 1963.

The Ninth Doctor (Christopher Eccleston) and Eleventh Doctor (Matt Smith) are the only Doctors to never encounter the Master on-screen. Although the Master wasn't introduced until the Third Doctor (Jon Pertwee) stories, the First (Richard Hurndall, for the late William Hartnell) and Second (Patrick Troughton) Doctors have crossed paths with the Master in the 20th Anniversary special Doctor Who: The Five Doctors (1983).

Peter Capaldi insisted on "no romance" with his companions. His Doctor, unlike his predecessors, the Tenth and Eleventh Doctors, did not share a romantic on-screen kiss with his wife, River Song.

Stephen Fry was set to write an episode for season two, but due to budget constraints, the episode was pushed back to season three. The script was eventually cancelled, as Fry didn't have the time to re-write the script to accommodate changes such as Rose's replacement Martha.

The series is recorded on single-camera digital video and then in post-production it is "filmized", a digital process designed to make it look like it was made on film. The process is so successful that even people who worked on the original series, such as director Christopher Barry and producer Philip Hinchcliffe, have mistakenly commented that the revived series is made on film.

David Tennant became the fourth actor from the series to appear in the Marvel Cinematic Universe on January 27, 2015, when it was announced that he would be be starring as Kilgrave in Jessica Jones (2015). Jenna Coleman appeared in Captain America: The First Avenger (2011), Christopher Eccleston appeared in Thor: The Dark World (2013), and Karen Gillan appeared in Guardians of the Galaxy (2014), Guardians of the Galaxy Vol. 2 (2017), Avengers: Infinity War (2018), and Avengers: Endgame (2019).

Despite quite a lot of new scenes being added to episodes in post-production during the first season, all thirteen episodes ran under the standard length of forty-five minutes, so teaser trailers for the next week's episode were tacked on to bring the length up to standard. This then became a staple of the show from 2005 onwards until season eleven, which brought each episode up to fifty minutes (excluding certain episodes).

The Eleventh Doctor spent nine hundred years on Trenzalore before his regeneration in Doctor Who: The Time of the Doctor (2013), almost half of his lifetime as depicted over the entire fifty year run. This also technically makes Handles, the Cyberman head that keeps him company over the centuries, the Doctor's longest-serving companion, besides the T.A.R.D.I.S.

Christopher Eccleston and David Tennant previously collaborated with Russell T. Davies before being cast as The Doctor. Eccelston in The Second Coming (2003), and Tennant in Casanova (2005). Eccelston also auditioned for a part in Queer as Folk (1999).

The two-part season finale, Doctor Who: Army of Ghosts (2006) and Doctor Who: Doomsday (2006), is the first time that The Daleks and Cybermen both appeared and met each other on-screen.

Karen Gillan stated in a 2017 interview, that she would love to come back as Amy Pond.

Steven Moffat credits The Time Traveler's Wife (2009) as a big influence on writing Doctor Who: The Girl in the Fireplace (2006) and the creation of River Song. Alex Kingston mentioned the novel in an interview, saying The Doctor and her character keep missing each other.

Future Companion and Doctor Karen Gillan and Peter Capaldi appeared in Doctor Who: The Fires of Pompeii (2008), in different roles. Gillan as a Soothsayer, and Capaldi as Caecilius. The Soothsayer had not been considered by Steven Moffat to be an ancestor of Amy Pond, and in Doctor Who: Deep Breath (2014), when the Twelfth Doctor sees himself in the mirror, he remembers Caecilius, and remarks that he had seen that face before. Both Scottish cast members would appear together again in Doctor Who: The Time of the Doctor (2013), in which Gillan made a cameo as Amy Pond, and Capaldi appeared in the final seconds as the newly regenerated Twelfth Doctor.

Russell T. Davies had a policy of not employing writers from the original series. Bob Baker, who was a writer during the Jon Pertwee and Tom Baker years, contacted Davies and offered to write for the series, but was told he was not wanted.

Robin Williams (a fan of the show) was offered the role of the War Doctor (a non-traditional casting choice for a non-traditional Doctor), was honored to be asked, but declined as he was suffering from the depression that he ultimately succumbed to at the time. His family have stated when he watched the 50th, there were several scenes that made him more excited than he had been in a long time.

Alex Kingston and John Barrowman have the same birthday, both play recurring characters, and have been on Arrow (2012).

Georgia Moffett auditioned for the role of Rose Tyler, but didn't get the part, because it was felt by Russell T. Davies that she was too young, and the part went to Billie Piper.

Former Head Writer and Producer Russell T. Davies had been offered by his successor Steven Moffat to write episodes for the series, but Davies declined.

The Doctor performing a guitar solo on top of a tank in Doctor Who: The Magician's Apprentice (2015) was inspired by Mad Max: Fury Road (2015), which The Doof Warrior performs electric guitar solos on top of his Doof vehicle.

Special Effects Model Worker Mike Tucker, Director Graeme Harper, K-9 Operator Mat Irvine, and Costume Designer Barbara Kidd are the only technical crew members to have also worked on the original show.

In 2008, Russell T. Davies became the first Doctor Who writer since its beginning on television in 1963 to be honored by the Queen, receiving an O.B.E. He also became only the second producer of the series to receive such an honor (original producer Verity Lambert was made an O.B.E. in 2002). In 2015, Steven Moffat became the third lead producer of the series to be awarded an O.B.E..

Almost everyone connected to the series was completely delighted by the casting of Jodie Whittaker as the 13th Doctor and the Doctor's change from a Time Lord to a Time Lady. However, Peter Davison caused a stir when he said that he regretted the loss of "a role model for boys". The resultant backlash against him was so ferocious that he closed his Twitter account, saying the "toxicity" around the series had been "sobering".

Jodie Whittaker and Matt Smith are good friends in real-life.

While David Tennant was always the first choice for the role of the Tenth Doctor. Chris Barrie, Bill Nighy, and David Walliams were also considered for the role.

David Tennant, Olivia Colman, Arthur Darvill, and Eve Myles went on to star in Broadchurch (2013). Directors of the series, like James Strong and Euros Lyn, also worked on that series.

Michael Grade, an outspoken critic of the original series for many years and the former BBC One controller who incurred the wrath of many fans when he took it off the air in 1985 for eighteen months (and also sent down orders to have Colin Baker fired in 1986), admitted that he was completely won over by this revival of the series, which he described as "a classy, popular triumph for people of all ages and all backgrounds, real value for money for our licence fee payers." In 2012, he told Radio Times: "From clunky Daleks that couldn't go up and down stairs to the filmic qualities today of Doctor Who, it's a transformation. The show still leaves me cold, but I admire it, which I never did before."

For the fifth season, at the height of the show's promotional campaigns to other countries, the decision was made to have a narrated prologue sequence added to the start of every episode, where Amy provides a basic outline of the show. This prologue sequence only exists in syndicated versions, and isn't present in the initial U.K. airings.

Jenna Coleman auditioned for Mels, an earlier incarnation of River Song.

The Tenth Doctor says "what" in the end of every season finale, except the fourth, in which Matt Smith appeared.

Billie Piper was crying for real when they filmed Rose Tyler's goodbye scene at the end of Doctor Who: Doomsday (2006), and she continued crying when the director called "Cut!" and David Tennant, who was crying off-camera, hugged Billie Piper after they finished filming the scene.

When Jenna Coleman was auditioning for Clara Oswald, the name on the script was Jasmine, not Clara.

The choice of Russell T. Davies to write and produce the family series surprised some commentators, as he was most famous for writing the explicit and uncompromising adult drama about homosexual men in Manchester, Queer as Folk (1999).

In 2009, regular Writer Mark Gatiss took over role of Executive Producer on Steven Moffat's other series Sherlock (2010), in which Gatiss is co-Creator, so Moffat could concentrate on producing this show.

James McAvoy was rumored to play the Eleventh Doctor.

Matt Smith and Peter Capaldi injured their knees during filming, and eventually underwent surgery.

Steven Moffat, who succeeded Russell T. Davies as Head Writer and Producer of the revived series, wrote The Eleventh Doctor's brief scene and first lines at the end of Doctor Who: The End of Time: Part Two (2010), but was uncredited.

The character of Captain Jack Harkness (John Barrowman), who was introduced in the first season, was the first openly LGBT (lesbian, gay, bisexual, or transgender) character to be portrayed in the history of televised Doctor Who. Writer Ian Briggs had suggested a gay subplot for the characters of Judson and Millington in the serial Doctor Who: The Curse of Fenric: Part One (1989), but this had been vetoed by Producer John Nathan-Turner as unsuitable for a family audience at the time. Rona Munro also intended a lesbian subtext between Ace and Kara in Doctor Who: Survival: Part Three (1989), but felt this didn't come across properly.

Russell T. Davies was sounded out to produce a revival of the series by the BBC One Controller of the time, Peter Salmon, in 1999. Although nothing came of this due to BBC Worldwide's desire to make a movie version of the show, by late 2003, the new Controller of BBC One, Lorraine Heggessey, had persuaded Worldwide to surrender their movie ambitions so that she could commission a new television version.

On October 29, 2008, David Tennant announced that he was leaving Doctor Who after the four specials in 2009. On January 3, 2009, it was announced that Matt Smith would take over from him in 2010.

Matt Smith declined to stay on the show for the eighth season. He regretted that decision.

In the audio production of "Roses" featuring the First Doctor, which was a short story set after The Dalek Master Plan. The Doctor's granddaughter Susan's real name is revealed as Arkyitor. Arkyitor means "rose" in High Gallifreyan. The Ninth and Tenth Doctor's companion is Rose Tyler.

Jenna Coleman was rumored to leave after season eight, and that Clara would die of old age in Doctor Who: Last Christmas (2014). These were false. However, she left at the end of season nine.

Steven Moffat said that he originally planned to cast an older actor for the Eleventh Doctor. He had also previously said: "For Doctor Who to turn into an old man you'd be pissed off. Even William Hartnell had trouble back then, he was often ill and he forgot his lines. I think the Doctor will always be about forty." As Executive Producer, he then went against his own theory by casting the youngest Doctor ever (twenty-six-year-old Smith) and the oldest since Hartnell (fifty-five-year-old Capaldi).

River Song is the only companion who knows The Doctor's real name.

Matt Smith worked with Billie Piper in Sally Lockhart Mysteries: The Ruby in the Smoke (2006), and had a guest role in Secret Diary of a Call Girl (2007), prior to being cast as the Eleventh Doctor.

After leaving the series, David Tennant worked with Sophie Aldred on the BBC animated series Tree Fu Tom (2012), providing the voice of Twigs. Aldred played Ace, companion of the Seventh Doctor in the original series.

The prospect of a female Doctor had actually been mooted since 1980, when Tom Baker announced to the press that he was leaving the role and wished his successor the best "whoever he or she may be". However, it took another 37 years before this became a reality with the casting of Jodie Whittaker as the 13th Doctor.

In 2015, Sir John Hurt, who had played an alternative version of the Doctor known as the War Doctor in 2013, became the first actor to have played a version of the Doctor in the television series since 1963 to be awarded a knighthood.

Lara Croft, the main protagonist of the Tomb Raider games and movies, is a strong influence behind River Song. Like Lara Croft, River Song is an archaeologist who's known for using a gun.

Jenna Coleman, who was supposed to leave in season eight, was "badgered" into staying for season nine by Peter Capaldi and show runner Steven Moffat during the 2014 Doctor Who World Tour.

In the season six opener, Amy and Rory meet up with the Doctor after getting off a yellow school bus. With these being the first episodes filmed in America, the production team wanted to use purely American icons as much as possible. Initially, the Ponds were to get out of a pickup truck, but the bus was used instead, as that color on the vehicle was an American thing, and they don't have that color of bus in the U.K.

In Doctor Who: The Invasion of Time: Part Six (1978) in the original series. Borusa is seen reading a newspaper about the 1912 Titanic disaster, with which the Fourth Doctor claimed he had nothing to do. In Doctor Who: Rose (2005), Rose Tyler is shown an old photo of The Ninth Doctor, with a family in 1912, and is told that The Ninth Doctor told the family not to go aboard the Titanic, and that the family survived. In the 2007 Christmas Special Doctor Who: Voyage of the Damned (2007), The Tenth Doctor goes aboard the Sto passenger spaceship, which is named after the Titanic passenger liner that sunk in 1912.

In July 2015, there were false rumors that Karen Gillan would return as Amy Pond in season ten, in 2016, and that David Tennant and Tom Baker would appear in the 2015 Christmas Special.

While the 9th, 10th and 11th Doctors appeared to have specific catchphrases to each character ("Fantastic!""Allons-y!" And "Geronimo" respectively), the 12th Doctor never appeared to have a specific catchphrase. Rather, it appeared that his character would phrase certain elements of the story using the various steps of the Scientific Method (Question, Hypothesis, Analysis, et cetera) to describe the events in which he would find himself, or at times to explain events to people around him. This appears to be in keeping with Peter Capaldi's insistence that the Doctor is less interested in feelings and relating to people, and instead explaining things in a more cold and logical manner.

As Executive Producer, Steven Moffat received criticism for overly complicated and even indecipherable storytelling, with leading television critic Kevin O'Sullivan admitting in 2017 that he's "never understood a word Steven Moffat's ever written".

The Time War was not the only time The Daleks were on Gallifrey. In Doctor Who: The Five Doctors (1983), the 20th Anniversary special, a Dalek was seen pursuing the First Doctor and Susan in the Death Zone on Gallifrey.

Nick Frost, Simon Pegg, Toby Jones, and Tony Curran, who had guest roles in the series, appeared in The Adventures of Tintin (2011), which Steven Moffat co-wrote.

Rory Williams' father Brian is played by an actor whose surname happens to be Williams, Mark Williams.

Season nine experimented with a slightly different format, each story played out over two episodes, meaning each story was roughly the same length as a classic series four-parter.

With Peter Capaldi's Twelfth Doctor still to regenerate, every other Doctor (named since 2005), except for the Ninth (Christopher Eccleston), has regenerated in a story centered around the return of Gallifrey, including Sir John Hurt's brief stint as the War Doctor in Doctor Who: The Day of the Doctor (2013).

The song, in Doctor Who: Vincent and the Doctor (2010), featured in the scene, in which The Doctor and Amy take Vincent Van Gogh to visit the Art Gallery is "Chances" by Athlete.

Peter Capaldi announced that season ten will be his last season in the role of The Doctor on January 31, 2016, and that he will leave with Steven Moffat in the 2017 Christmas Special.

Tenth Doctor David Tennant and Twelfth Doctor Peter Capaldi were both huge fans of the original series growing up. Tennant's favorite was Fifth Doctor Peter Davison and Capaldi's favorite was Third Doctor Jon Pertwee. Tennant admitted that Doctor Who (1963) had made him want to be an actor in the first place (he also presented the Davison era documentary Come in Number Five (2011)), while Capaldi actually had a letter published in the Radio Times congratulating the production team on the quality of Pertwee's final serial, Doctor Who: Planet of the Spiders: Part One (1974). Incidentally, Tennant's favorite Doctor is now his father-in-law.

Georgia Moffett, daughter of Peter Davison (The 5th Doctor) appeared opposite her future husband David Tennant (The 10th Doctor) as Jenny in Doctor Who: The Doctor's Daughter (2008). David Troughton, son of Patrick Troughton (The 2nd Doctor) played Professor Hobbes in Doctor Who: Midnight (2008), and Karen Gillan's cousin Caitlin Blackwood played Amelia Pond in Doctor Who: The Eleventh Hour (2010) in seasons five and six.

In one of River Song's diary entries, The Doctor and River Song went to a picnic on Asgard. Christopher Eccleston, who played the Ninth Doctor, starred as the main antagonist Malakith in Thor: The Dark World (2013). Thor's realm is Asgard.

In Doctor Who Magazine, Karen Gillan was called "The New Sophie Aldred".

Several British politicians praised the Doctor's sex change in 2017, including Prime Minister Theresa May, who said she was "pleased" by the decision, and Scottish First Minister Nicola Sturgeon, who said "Lovely day with my niece on her 11th birthday. This was one of her pressies - girls can be anything, even Dr Who!". Labour's Harriet Harman had said earlier in the year: "Of course there should be a female Doctor Who but what we need is a man as her assistant. She has got to just tell him what to do, he will need that leadership." Even former Labour leader Ed Miliband tweeted to criticize Peter Davison, who had questioned the casting of a woman in the role.

In Supernatural (2005) season seven, episode three, "The Girl Next Door", Jewel Staite played a character named Amy Pond, who is a nod to the character played by Karen Gillan, and is seen as a child and an adult. Staite attended the Armageddon Pulp Culture Expo in Wellington, New Zealand in 2006, and Gillan attended the Armageddon Pulp Culture Expo in Wellington, New Zealand in 2015.

Sir John Hurt (The War Doctor) passed away on January 27, 2017. He's the first actor who has played The Doctor to pass away since Jon Pertwee, who died on May 20, 1996, and he is the fourth actor that has played The Doctor to pass away. William Hartnell (The First Doctor) died in 1975, and Patrick Troughton (The Second Doctor) died in 1986.

It was rumored that Sophia Myles, who played Madame de Pompadour in season two, episode four, "The Girl in the Fireplace", would replace Karen Gillan as the new companion in season seven. Steven Moffat denied the rumor, stating that her return in the series as The Doctor's new companion would be inappropriate, and Jenna Coleman was officially announced as the new companion, Clara Oswald.

Despite the many stories that take place in the U.S., the first episodes to be filmed in the U.S. were the season six opener two part. The 1996 television movie was filmed in British Columbia, while season six was shot in southern Utah, home of all the great early days of film. The landscape alone just screams America.

The series took a break in 2009 and 2016. Four hour long specials were broadcast throughout 2009 to mark the end of the Russell T. Davies and David Tennnat era: Doctor Who: Planet of the Dead (2009), Doctor Who: The Waters of Mars (2009), Doctor Who: The End of Time: Part One (2009) and Doctor Who: The End of Time: Part Two (2010), and Doctor Who: The Return of Doctor Mysterio (2016) was broadcast on Christmas Day 2016.

In Doctor Who: The Day of the Doctor (2013), The War Doctor asks The 11th Doctor if a lot of kissing happens in his future, which he replies that it does happen. The Doctor's first on-screen kiss was Dr. Grace Holloway in the 1996 television movie. In the series, The Doctor has been kissed by Captain Jack Harkness, Rose Tyler, Cassandra O'Brien, Madame De Pompadour, Jackie Tyler, Martha Jones, Joan Redfern, Astrid Peth, Donna Noble, Lady Christina De Souza, Amy Pond, River Song, Idris, Craig Owens, Clara Oswald, Queen Elizabeth I, and Missy.

In an interview for Radio Times in 2017, Steven Moffat described Matt Smith's Doctor as "more sexless and less of a lad" than David Tennant's and admitted that he could have replaced Smith with a woman, but instead became obsessed with seeing Peter Capaldi in the T.A.R.D.I.S., and had no regrets about that.

Oscar winner Eddie Redmayne expressed interest in playing The Doctor when Peter Capaldi leaves the series. Eddie Redmayne starred in Jupiter Ascending (2015) as Balem Abrasax. Christina Cole, who co-starred in the film as Gemma Chatterjee, played Lillith in Doctor Who: The Shakespeare Code (2007).

Because of the varying technical and logistical demands of the thirteen episodes of the first season, filming was broken into five production blocks. Episodes one, four, and five formed block one, and were filmed between July and September 2004. Block two comprised episodes two and three, and was filmed between September and October 2004. Block three contained episodes six and eight, and was filmed between October and December. Block four was split into two sub blocks, "4A" and "4B", due to the large visual effects demands of episode seven, which on its own, became block 4A, filmed between December 2004 and January 2005. Episodes nine and ten made up Block 4B, filmed from December through February 2005. Episodes eleven through thirteen formed Block five, and filmed from February until March 2005.

The series took a break in 2009 and 2016. However, four specials were broadcast throughout 2009 to mark the end of the Russell T. Davis and David Tennant era: Doctor Who: Planet of the Dead (2009), Doctor Who: The Waters of Mars (2009), Doctor Who: The End of Time - Part One (2009) and Doctor Who: The End of Time - Part Two (2010), and season five aired in 2010. Production on season ten commenced in July 2016, and The Doctor did return for the 2016 Christmas Special, Doctor Who: The Return of Dr. Mysterio (2016). The tenth season airs in 2017.

Within the series, the term "Doctor" is actually a closed loop paradox, as the Doctor claims to have inspired the term's definition as "healer and wise man" throughout the universe, but also having chosen the name because it meant someone who "makes people better".

Bernard Cribbins (Wilfred Mott) played Tom Campbell in Daleks' Invasion Earth 2150 A.D. (1966) opposite Peter Cushing as Dr. Who.

In real-life, Matt Smith had aspired to be a football player before becoming an actor. In Doctor Who: The Lodger (2010), Matt Smith got the opportunity to show off his football skills as The Eleventh Doctor plays a game of football.

Season eleven was the first season not to have a recurring arc and the Daleks and the Cybermen didn't appear.

The main theme of season eleven is prejudice. The 13th Doctor is female. Ryan Sinclair is black British. Yasmin Khan is British Pakistani Indian. The Doctor and her companions meet Civil Rights activist Rosa Park. They travel to India in 1947. They meet a pregnant man called Yoss, and women in seventeenth century England are accused of witchcraft by Becka Savage.

In Utopia (2007) there are more flashbacks than any other episode in the new series.

It was rumored that Lucy Lawless was going to play The Doctor in a Comic Relief special. However, the rumor was false.

The Eleventh Doctor is known for wearing a fez, but he was not the only Doctor to do so. In Doctor Who: Silver Nemesis: Part One (1988), the Seventh Doctor was briefly seen wearing a fez.

If Russell T. Davies remained as showrunner in 2010. Lady Christina De Souza (Michelle Ryan) may have been brought back as a full-time companion of the Eleventh Doctor.

Doctor Who: Season 2, Volume 2 (2006) was the first DVD release of the series to be given the "M" rating in New Zealand. Mostly due to the opening fight scene in Doctor Who: Tooth and Claw (2006). Doctor Who: The Complete Eighth Series (2014) and Doctor Who: Series 9 Part 1 and Doctor Who: Season 9 Part 2 (2015) were also given the "M" rating.

Peter Capaldi (The Doctor) and Nigel Betts (Mr. Frank Armitage) are the only actors to play the same characters in Doctor Who (2005) and Class (2016).

In 2017, Hayley Atwell was linked to playing the first female Doctor, but stated that she wasn't interested in the part.

According to journalist and broadcaster Mark Lawson, Russell T. Davies "turned into a global cash cow a series that had come to be ridiculed by many for cheap and creaking representations of planets and aliens. To play the two-hearted Time Lord from Gallifrey, he cast the sort of actors, Christopher Eccleston and David Tennant, who play Hamlet on stage."

Amy Pond's introduction in the title sequence in season six was omitted from the DVD release.

Some broadcasters number the 2005 revival seasons, as if part of the original series run. For example, Jodie Whitaker's first season as The Doctor, is listed by cable television company Virgin Media Ireland for the BBC One first broadcasts in 2018, as season sixty-three.

Like her predecessor, Peter Capaldi, Jodie Whittaker has been allowed to keep her strong, regional accent in her rendition of the Doctor. This makes David Tennant the only actor (at least in the 2005 renewed series) who puts on an accent for the role, despite that his natural dialect is arguably much easier to understand than Jodie's (as is evident, for instance, by the popularity of subtitled torrents of the eleventh season).

Steven Moffat went on record in a interview stating that season seven was the worst season of this show, and that the workload was insane, and he didn't cope well, and he had tough time with Matt Smith leaving the show.

Four years before Jodie Whittaker was cast as the Thirteenth Doctor, Dame Helen Mirren had been linked to playing the Twelfth Doctor. When she was asked about this by Aled Jones for Daybreak (2010), Mirren had said she wouldn't contemplate playing the Doctor, but she said that it was "well over time to have a female Doctor Who. I think a gay, black female Doctor Who would be best of all." Mirren was also quoted by What's On TV as saying: "I think it's absolutely time for a female Doctor Who. I'm so sick of that man with his girl sidekick. I could name at least ten wonderful British actresses who would absolutely kill in that role."

K-9 is briefly mentioned in Tom Anglebergers' Emperor Pickletine Rides the Bus, in a drawing labelled as the best television dog ever. This is the latest book (as of November 10, 2016) in his Origami Yoda series.

According to Jodie Whittaker, for several weeks leading up to the official announcement, only a handful of people knew that she had been cast as the Doctor. The only people she was allowed to tell were her husband and her agent. This was slightly expanded when the brief teaser of Whittaker was filmed with a minimal staff. Several individuals associated with the series, including former Doctor Matt Smith, were informed a few hours before the announcement aired.

Television critic Kevin O'Sullivan said in 2018 that the appointment of Jodie Whittaker as the first female Doctor had "revived interest in an ailing entity".

Paul McGann returning in Doctor Who: The Night of the Doctor (2013) was done to connect Doctor Who (2005) with Doctor Who (1996), and to reveal how The Eighth Doctor regenerated.

Karen Gillian (Amy Pond) appeared in season four, episode three, "The Fires of Pompeii", as a soothsayer, before becoming the Doctor's companion.

Russell T. Davies did not want to bring back The Daleks and had planned to replaced them with silver spheres with human faces called the Toclafane. However, Russell T. Davies agreed to bring the Daleks back in season one and the Toclafane were re-used for season three.

Mark Gatiss had been lobbying for a female Doctor for a very long time and described it as "well overdue".

Doctor Who: The Girl Who Waited (2011) is the first and only episode to have female nudity. Rory encounters a statue of the Venus De Milo in the Two Steams facility on Apalapacia. The statue's bare breasts are seen.

Janet Fielding said of the casting of Jodie Whittaker: "Dinosaurs have fifty years' worth of male Dr. Whos to watch in their basements. The rest of us want to embrace the future."

Kris Marshall, Vicky McClure, Andrew Buchan, David Harewood, James Norton, Tom Rosenthal, Michaela Coel, Natalie Dormer, Richard Dean Rankin, Tilda Swinton, Alexander Vlahos, Ben Whishaw, Maxine Peake, Olivia Colman, Richard Ayoade, and Phoebe Waller-Bridge were all frontrunners to replace Peter Capaldi as The Thirteenth Doctor, before Jodie Whittaker was cast.

When this show was in development, Jane Tranter and Lorraine Heggesssey talked about Lois & Clark: The New Adventures of Superman (1993), which was a "fantasy drama on a Saturday night", and that they wanted the new series of Doctor Who to be something like that, which helped Russell T. Davies to get the tone of the show and wanted the new series to have the warmth, the colors and wit which the Superman television series had, and to have its own mythology.

Doctor Who: The Angels Take Manhattan (2012) was the first episode of this show to be given a viewer warning at the beginning of the episode when it aired on Prime in New Zealand. All episodes of this show are rated PGR Parental Guidance Recommended in that country.

From 2005 to 2013, all DVD releases of this show were given in the PG rating in New Zealand. Seasons eight, nine, and ten were all given the "M" mature rating.

In 2017, Tom Baker told interviewer Cameron K. McEwan for GQ that Dawn French would be a good choice for the Doctor because "she's got such a wry sense of humor and also has a way with her that faintly suggests she's got secrets."

From 2005 to 2010, this show was released on DVD individually in volumes. Later, the series was released on DVD as complete seasons.

Although Steven Moffat created River Song, Alex Kingston was cast in the role by Russell T. Davies. Originally, Russell T. Davies had wanted Kate Winslet for the role, after he had worked with her on Dark Season (1991). But, Russell T. Davies decided to cast Alex Kingston instead.

It was falsely rumored that Arthur Davill was returning to the series as The Master.

In Doctor Who: The Doctor Dances (2005), Captain Jack Harkness shoots off a doorknob with a sonic blaster which was built in the weapon factories on Villengard in the fifty-first century. In Doctor Who: Twice Upon A Time (2017), the 1st and 12th Doctor and Bill Potts travel to Villengard in the fifty-first century as the 12th Doctor seeks help from the rogue Dalek Rusty for information on the Testimony.

References to Doctor Who (1963) including the appearances of Sarah Jane Smith, K9, the Fifth Doctor, the Eighth Doctor, the First Doctor, Alpha Centauri, et cetera, were put in the series to connect this show with Doctor Who (1963) and Doctor Who (1996), and to establish that it wasn't a reboot, but a revamp and a direct continuation, and that Doctor Who: Rose (2005) takes place years after Doctor Who: Survival: Part Four (1989) and Doctor Who (1996). Doctor Who: Night of the Doctor (2013) is a prequel revealing the fate of the 8th Doctor (Paul McGann) and his regeneration into the War Doctor (Sir John Hurt), who came before the 9th Doctor (Christopher Eccleston).

The Twelfth Doctor is seen working as a tutor at the fictitious St. Luke's University, Bristol during the tenth season. Location work was shot at Cardiff University.

Before Michelle Gomez joined the series as Missy, Charles Dance was falsely rumored to replace John Simm as The Master.

There was a false fan theory that Ashildr (Maisie Williams) and Missy (Michelle Gomez) were the same person.

As of 2018, Doctor Who: The Parting of Ways (2005) is the only Regeneration episode of the revived series not to be a Christmas Special nor a New Year Special.

David Bradley, who has been cast in the series twice as the First Doctor (and also played William Hartnell in An Adventure in Space and Time (2013)), is the third actor to play this version of the Doctor. Following the death of William Hartnell in 1975, the second actor had been Richard Hurndall in Doctor Who: The Five Doctors (1983). The First Doctor remains the only version of the Doctor which has been re-cast with another actor in either Doctor Who (1963) or Doctor Who (2005).

The left-wing political activist Billy Bragg said of the casting of Jodie Whittaker: "Brilliant! The new Dr. Who is a young, intelligent woman. Those who are in the exact opposite categories will doubtlessly be whinging about it."

Mark Ayres, a musician and composer closely associated with this show, said of the casting of Jodie Whittaker: "Anyone upset it has a girl in it needs to get over themselves."

During production of Doctor Who: The Wedding of River Song (2011). Matt Smith was interviewed on the set about Elisabeth Sladen, who died on April 19, 2011.

Phil Davis, who played Lucius in the 2008 entry "The Fires of Pompeii", tweeted his delight at the casting of Jodie Whittaker and said "Never mind the clap-trap."

It was rumored online that Jodie Whittaker and Chris Chibnall will leave the series in 2019.

Sam Troughton, grandson of the late Patrick Troughton (the 2nd Doctor) had expressed interest in playing a villain on this show.

David Troughton, son of Patrick Troughton, who played the 2nd Doctor in the original series appeared in Doctor Who (1963) and this show as different characters.

Australian jail series Wentworth (2013) has paid discreet homage to this show with its episode names, as one in each season has mirrored a "Nu-Who" title: "The Girl Who Waited", "Fear Her", "The Long Game", "Eleventh Hour", and "Hell Bent".

Steven Moffat named Rusty the Good Dalek after previous showrunner Russell T. Davies.

During the March 26, 2005 broadcast of Doctor Who: Rose, Graham Norton was heard saying "Am I on the sofa? or are there many out there?" and "Am I here?" in the scene which Rose Tyler meets the 9th Doctor.

Head Art Designer Arwel Jones once asked Jodie Whittaker if she had a favorite biscuit, to which she responded custard creams (two biscuit layers with a custard filling). When Jodie filmed her first scenes in the new T.A.R.D.I.S. set, she was directed to step on a pedal located on the console. When she did, much to her surprise and joy, a custard cream biscuit slid down from a dispenser, which Jones included in the set specifically for her as a surprise. Her reaction to the biscuit was filmed and ended up in the finished episode (Doctor Who: The Ghost Monument (2018)).

When the BBC started releasing this show on DVD, seasons one through five were released individually in volumes. In 2011, the BBC started releasing the series on DVD as full seasons. However, seasons six, seven, and nine were all released as two volumes. Seasons six and seven, but not season nine, had midseason breaks.

Prior to becoming a regular writer and showrunner, Steven Moffat wrote the 1999 spoof "The Curse of Fatal Death" for Comic Relief with Rowan Atkinson as the 9th Doctor, Richard E. Grant as the 10th Doctor, Jim Broadbent as the 11th Doctor, Hugh Grant as the 12th Doctor, Joanna Lumley as the 13th Doctor, Jula Sawalha as Emma, and Jonathan Pryce as The Master. Julia Sawalha had auditioned for Ace, and Richard E. Grant played Dr. Simeon in season seven, and the Doctor finally changed his gender from male to female in the 2017 Christmas Special.

At the start of the third season, Martha Jones is working as a medical student at the (fictional) Royal Hope Hospital in Westminster, London.

Steven Moffat's 1999 Comic Relief spoof of Doctor Who (prior to the reboot of the series) had a woman, Joanna Lumley, as the 13th Doctor, unknowingly foreshadowing the casting of a woman as the 13th Doctor after Steven's departure, and replacement by Colin Chibnall.

When Jenna Coleman was announced to replace Karen Gillan as The Doctor's companion in season seven, it was falsely rumored that Jenna Coleman would be playing Cleopatra. Cleopatra was mentioned by Mickey Smith in season two's "The Girl in the Fireplace" and River Song disguised herself as Cleopatra in season five's "The Pandorica Opens".

In each season, there is an underlying story arc that pans all episodes until finally fully addressed in the season finale. For season one, it is the concept and identity of the Bad Wolf. Season two, the Torchwood Institute. Season three, the identity of Mr. Saxon. In season four, there are several little references and jokes that eventually lead to the plot of the finale, including the missing planets and the bees disappearing from Earth, and repeated appearances of Rose Tyler on screens and monitors. In addition, there are repeated references to there being something on Donna's back. While this does not carry on to the season finale itself, it does play an important part in the episode which sets up the finale's story. In season five, there are "cracks" in the universe, which must ultimately be fixed in the season finale. In season six, a future version of the Doctor is seen to be killed, causing complications for the "present" version of the Doctor and his companions, also there is the repeated appearance of Madame Kovarian who only Amy can see. Season seven revolves around the "impossible" Clara Oswin Oswald, who the Doctor keeps running into in various places and times, though she does not remember him. In season eight, it is the identity of the mysterious Missy and where the people are going after they die, while season nine deals with the identity of the long-prophesied "hybrid" of two powerful warrior races, believed to be the Daleks and the Time Lords. Season ten focuses on the Doctor taking a job as a lecturer at a university, in order to guard a secret vault underneath it, that is later revealed in episode six to contain Missy, who he then begins to help become "good" again.

Almost all of the Doctors from the modern era (that have regenerated) have seen the first person they met in their new body just before they move on to the next incarnation. David Tennant regenerated in front of Rose, and then visited her before succumbing to radiation in the T.A.R.D.I.S. Matt Smith crash landed in Amelia Pond's garden, and also hallucinated her saying goodbye to him before he regenerated ("the first face this face saw"). Christopher Eccleston regenerated alone in the T.A.R.D.I.S., and, as of September 2015, his first moments have not been revealed, but certain scenes in Doctor Who: Rose (2005) (such as him studying himself in Rose's mirror), imply that he was new to his body. At the very least, this confirms that Rose was his first (and only) companion, possibly the first person to whom he ever spoke. -The only Doctor, to whom this does not apply, is the War Doctor, who regenerated from Paul McGann's Eighth Doctor in front of the Sisterhood of Karn (Doctor Who: The Night of the Doctor (2013)), but regenerated alone in his T.A.R.D.I.S. after the events of Doctor Who: The Day of the Doctor (2013). In fact, the last people he saw before changing were the Tenth and Eleventh incarnations of his future self (and Clara).

In real-life, David Tennant dated Sophia Myles, and later married Georgia Moffett. Madame de Pompadour died at the end of Doctor Who: The Girl in the Fireplace (2006), and at the end of Doctor Who: The Doctor's Daughter (2008), Jenny dies from a gunshot wound, but is revived.

In the season eight finale, Clara lied to the Cybermen, that she never existed, and she was actually the Doctor all along. This is preceded by the opening credits, that revealed Jenna Coleman's name first, instead of Peter Capaldi and Clara's eyes, instead of the Doctor's, as if to trick the audience into thinking that she really is the Doctor.

In Doctor Who: The Time of the Doctor (2013), The Eleventh Doctor has aged into a frail old man after nine hundred years on Trenzalore. Although Time Lords can regenerate into a new body and a new face, and they can make themselves younger, they can still age like normal humans. In Doctor Who: Time Crash (2007), The Tenth Doctor meets an older Fifth Doctor (Peter Davison was fifty-five or fifty-six). In Doctor Who: The Day of the Doctor (2013), The Eleventh Doctor encounters an elderly Fourth Doctor (Tom Baker was sixty-nine or seventy), a future incarnation, who modeled himself after one of his earliest incarnations. It's obvious the First Doctor (William Hartnell, who was fifty-five when he first played The Doctor) had started off young, and had grown old when he stole the T.A.R.D.I.S., and left Gallifrey with Susan.

Steven Moffat had wanted Christopher Eccleston to appear as the Ninth Doctor in the 50th Anniversary Special. But, Christopher Eccleston refused, and Steven Moffat replaced him with a new character, and wrote into Doctor Who: The Name of the Doctor (2013), Doctor Who: Night of the Doctor (2013), and Doctor Who: The Day of the Doctor (2013). In Doctor Who: Night of the Doctor (2013), it is revealed the Eighth Doctor (Paul McGann) was killed in a spaceship crash, but was temporarily revived by the Sisterhood of Karn, and he was given a potion that helped him regenerate into a new form of his choice, and the Eighth Doctor regenerated into the War Doctor (Sir John Hurt) and the War Doctor returned to Gallifrey to fight in the Time War. It is also revealed that the War Doctor, is the real Ninth Doctor, and the Eleventh Doctor is actually the Thirteenth and final Doctor, due to the Tenth Doctor being shot by a Dalek, and using the regenerative energy from his severed hand to heal himself and to stay the same, making him both the Eleventh and Twelfth Doctor. Sir John Hurt died on January 27, 2017.

In the 2008 audio story of Doctor Who: The Companion Chronicles "The Catalyst", it was revealed that Leela (Louise Jameson), companion of The Fourth Doctor (Tom Baker), had survived the destruction of Gallifrey in the Last Great Time War, and Leela had been captured and imprisoned by a warrior race called the Z'nai, and they interrogated Leela for information on the Time Lords.

This show could have ended with The Doctor using up all his regenerations and the death of the 13th Doctor. In Doctor Who: The Day of the Doctor (2013), it's revealed The War Doctor (Sir John Hurt) is the 9th Doctor and he came between the 8th Doctor (Paul McGann) and the 9th Doctor (Christopher Eccleston). The 10th Doctor (David Tennant) had regenerated twice. The first time, he was shot by a Dalek and he used the regenerative energy from his severed hand to heal himself. Thus making the 11th Doctor (Matt Smith) his 13th and final incarnation. In Doctor Who: The Time of the Doctor (2013), Clara begs the Time Lords to save The Doctor, and the Time Lords give The Doctor a new regeneration cycle, and The Doctor regenerates into his new form (Peter Capaldi).

At the end of Doctor Who: Tooth and Claw (2006), Queen Victoria not only sets up the Torchwood Institute to deal with extra-terrestrial and supernatural threats, she sets up Torchwood to do battle with The Doctor believing The Doctor is actually evil and proclaimed The Doctor as an enemy of Great Britain.

Jodie Whittaker's first scene as the 13th Doctor at the end of the 2017 Christmas Special mirrored Matt Smith's first scene as the 11th Doctor in the closing minutes of Doctor Who: The End of Time: Part 2 (2010), in which both the 10th and 12th Doctor's regenerations damages the T.A.R.D.I.S., setting the T.A.R.D.I.S. console room on fire, and causing the T.A.R.D.I.S. to violently tumble towards the Earth.

River Song's real name is "Melody Pond". This is considered clever writing by Steven Moffat and clever foreshadowing. A "river" is a large natural stream of water following in a channel to the sea, a lake, or another river. A "pond" is a small body of still water formed naturally or by artificial means. A "song" is a short poem or other set of words set to music or meant to be sung, and a "melody" is a sequence of single notes that is musically satisfying, a tune.

Clara Oswald discussing about what a good man should be in the classroom in the opening scene of Doctor Who: Day of the Doctor (2013) foreshadows the 12th Doctor asking Clara if he's a good man, which Clara answers "I don't know." in Doctor Who: Into The Dalek (2014).

Missy revealing herself as The Master to The Doctor in Doctor Who: Dark Water (2014) and the War General regenerating into a woman in Doctor Who: Hell Bent (2015) are a strong foreshadowing of The Doctor regenerating into his first female form at the end of Doctor Who: Twice Upon A Time (2017).

At the end of Doctor Who: Kill The Moon (2014), Clara is angry with The Doctor for abandoning her on the moon and leaving her to decide the future of the human race. It was established in the original series that Time Lords have a strict policy to never interfere in the affairs of other planets and that they cannot change or alter fixed points in history. The Doctor, a Time Lord, cannot interfere with the course of human history and it wasn't The Doctor's right to decide the destiny and future of the human race.

In October 2017, it was announced that Chris Chibnall is changing the series' format in season eleven, and that season eleven will have only ten episodes, and instead of forty-five minutes, each episode will be sixty minutes, and that the ten episodes in school eleven will focus more on historical eras.

In the two part season ten finale, The Doctor, Bill, and Nardole arrive aboard a colony ship that is transporting a humanoid race to another planet. But, The Doctor soon discovers that The Master, disguised as "Razor", is helping create the Cybermen, and that the planet to which the ship is travelling, is Mondas. In Doctor Who: Twice Upon A Time (2017), the T.A.R.D.I.S. brings The Doctor to the South Pole in 1986 in the aftermath of the destruction of Mondas, and meets his original incarnation moments before he regenerated.

The 2017 Christmas Special, Doctor Who: Twice Upon A Time (2017) is a direct continuation of Doctor Who: The Doctor Falls (2017). In the two part season ten finale, The Doctor, Bill, Nardole, and Missy discover the planet to which the colony ship is transporting a race of humanoids, is Mondas, and that The Master is helping create the Mondasian Cybermen, and The Doctor meets his original incarnation in the South Pole shortly after the destruction of Mondas and moments before the 1st Doctor regenerated.

Torchwood is a recurring story-arc throughout season two: In "The Christmas Invasion", Harriet Jones orders Torchwood to fire on the Sycorax ship. In "Tooth and Claw", Queen Victoria decides to set up the Torchwood Institute to deal with alien and supernatural threats and also to fight The Doctor believing The Doctor is evil. In "Army of Ghosts", The Doctor and Rose visit the Torchwood Institute in Canary Warf and learns Torchwood has a mysterious sphere and are behind the ghosts on present-day Earth, and in "Doomsday", the Daleks and the Cybermen take over the Torchwood Institute and the Torchwood Institute becomes a battle zone as The Daleks rejects the Cybermen's offer of an alliance and both robot races fight each other.

Chris Chibnall announced that he would be making lots of changes to this show in season eleven, and that the series' format would be changed from forty-five minutes to sixty minutes. The series would be given a cinematic feel and season eleven would focus more on historical stories.

In Doctor Who: The Magician's Apprentice (2015), when Clara is talking to Missy, Missy claims that she has cared for The Doctor since she was a little girl, which could be a lie. In the original series, it was established William Hartnell was The Doctor's original incarnation, and that Time Lords can only regenerate twelve times, which Time Lords can gain new regeneration cycles, and in the new series, it's revealed the Time Lords got their ability to regenerate by looking into the Untempered Schism. If The Doctor had regenerated as a child, the 12th Doctor would have been his 13th and final incarnation. However, when the Eleventh Doctor regenerates, he gets regeneration energy from all other Time Lords, and thus doesn't know how many regenerations he will have.

River Song meeting Donna Noble in Doctor Who: Silence in the Library (2008) foreshadows River Song revealing herself as Amy Pond and Rory William's daughter Melody in the climax of Doctor Who: A Good Man Goes to War (2011). Donna Nobel and Amy Pond have red hair, and it's likely Donna may had reminded River of Amy.

In the classic series, it was never established that The Doctor and other Time Lords could change gender when they Regenerate and Romana, The Rani, Chancellor Flavia, and The Inquisitor were the first Time Ladies to appear in the Doctor Who universe. In season eight, Missy reveals herself as the first female incarnation of The Master. In season nine, The General regenerates into a bald woman, and in the 2017 Christmas special, The Doctor regenerates into his first female incarnation.

The Master being revealed as the creator of The Cybermen in Doctor Who: World Enough and Time (2017) may had been influenced by Power Rangers: Reinforcements from the Future: Part 2 (2002), in which recurring antagonist Ransik (Vernon Wells) is revealed to have created the Mutant-Orgs.

The recurring story-arcs of season eleven is Graham struggling to come to terms with the loss of Grace and Tzim-Sha.

In the 2005 Christmas Special, The Doctor is furious when Prime Minister Harriet Jones orders Torchwood to fire on the Sycroax ship, and tells The Doctor that he won't always be there to save them. Harriet Jones is right about what she says and that The Doctor won't always be around to save the Earth from extra-terrestrial threats.
