Doctor Who in the context of "Ncuti Gatwa"

The title character in a narrative work is one who is named or referred to in the title of the work. In a performed work such as a play or film, the performer who plays the title character is said to have the title role of the piece. The title of the work might consist solely of the title character's name – such as Michael Collins or Othello – or be a longer phrase or sentence – such as Alice's Adventures in Wonderland or The Adventures of Tom Sawyer. The title character is commonly – but not necessarily – the protagonist of the story. Narrative works routinely do not have a title character and there is some ambiguity in what qualifies as one.

Examples in various media include Figaro in the opera The Marriage of Figaro, Giselle in the ballet of the same name, the Doctor in the TV series Doctor Who, Dr. Gregory House of the TV series House, Mario and Luigi in the video game Super Mario Bros., Harry Potter in the series of novels and films, and Romeo Montague and Juliet Capulet in the play Romeo and Juliet.

The Doctor, sometimes known as Doctor Who, is the protagonist of the long-running BBC science fiction television series Doctor Who. An extraterrestrial Time Lord, the Doctor travels the universe in a time travelling spaceship called the TARDIS, often with companions. Since the show's inception in 1963, the character has been portrayed by fourteen lead actors. The transition to each succeeding actor is explained within the show's narrative through the plot device of regeneration, a biological function of Time Lords that allows a change of cellular structure and appearance with recovery following a mortal injury.

A number of other actors have played the character in stage and audio plays, as well as in various film and television productions. The Doctor has also been featured in films and a vast range of spin-off novels, audio dramas and comic strips.

Matthew Robert Smith (born 28 October 1982) is an English actor. He is best known as the Eleventh Doctor in Doctor Who (2010–2013), Prince Philip, Duke of Edinburgh in The Crown (2016–2017) for which he received a Primetime Emmy Award nomination and Daemon Targaryen in House of the Dragon (2022–present).

Smith initially aspired to be a professional footballer, but spondylolysis forced him out of the sport. After joining the National Youth Theatre and studying drama and creative writing at the University of East Anglia, he became an actor in 2003, performing in plays including Murder in the Cathedral, Fresh Kills, The History Boys and On the Shore of the Wide World in London theatres. Extending his repertoire into West End theatre, he has since performed in the stage adaptation of Swimming with Sharks with Christian Slater, followed a year later by a critically acclaimed performance in That Face.

The Time Lords are a fictional ancient race of extraterrestrial people in the British science fiction television series Doctor Who. In-universe, they hail from the planet Gallifrey and are stated to have invented time travel technology. They have sworn an oath to not interfere in the universe; those who reject this and leave the planet to live in the universe are referred to as "renegades". One of their number, the Doctor, fled Gallifrey, stealing one of their time machines known as a TARDIS. In the early days of the series, the Time Lords were not initially referred to, and though the Doctor was stated to be non-human, the character did not clarify beyond that. The Time Lords, as well as the Doctor's affiliation with them, first appeared in the 1969 serial The War Games. Following this appearance, the Time Lords serve as recurring characters, with many individual Time Lords serving either antagonistic or supporting roles in the series. Following the show's 2005 revival, it is revealed the Time Lords had been wiped out in-universe, killed by the Doctor during the events of a war against a species known as the Daleks. Though the Doctor is later able to go back and save the Time Lords in the 2013 episode "The Day of the Doctor", they are killed again by the antagonist the Master during the events of the 2020 episode "Spyfall".

The Time Lords originally did not exist in the series' narrative, though the Doctor referred to not being human. When creating 1969 serial The War Games, the production team needed a way to resolve the narrative of the serial in a satisfying manner. The team decided to have him meet his own people to bring the narrative back to the Doctor's origins. The Time Lords are believed to have been conceived by producer Derrick Sherwin, who initially had assumed they were a pre-existing element in the series. Sherwin discussed and planned out the Time Lords' role with co-writer Terrance Dicks, laying the groundwork for the Time Lords' future appearances in the series. Though the Time Lords were initially portrayed as god-like figures, they were recontextualised significantly by the 1976 serial The Deadly Assassin. The serial depicted them as having internal political struggles, with Time Lords being hypocritical and corrupt in their nature. The serial also established a distinct visual identity for the Time Lord race, having them wear ceremonial robes and large collars. This depiction of the Time Lords would be maintained throughout the rest of the show's original run. The show's 2005 revival would end up killing the Time Lord race due to showrunner Russell T Davies finding the Time Lords boring, while also wanting to establish them as mythological figures in the series' lore. The following showrunner, Steven Moffat, would bring them back to establish a new character arc for the Doctor, allowing the character to move on from their guilt caused by their actions in destroying them.

The TARDIS (/ˈtɑːrdɪs/; acronym for "Time And Relative Dimension(s) In Space") is a fictional hybrid of a time machine and spacecraft that has, since 1963, appeared in the British science fiction television series Doctor Who and its various spin-offs. While a TARDIS is capable of disguising itself, the exterior appearance of the Doctor's TARDIS typically mimics a police box, an obsolete type of telephone kiosk that was once commonly seen on streets in Britain in the 1940s and 50s. Its interior is shown as being much larger than its exterior, commonly described as being "bigger on the inside".

Due to the significance of Doctor Who in popular British culture, the shape of the police box is now more strongly associated with the TARDIS than its real-world inspiration. The name and design of the TARDIS is a registered trademark of the British Broadcasting Corporation (BBC), although the design was originally created by the Metropolitan Police Service.

In the long-running BBC television science fiction programme Doctor Who and related works, the term "companion" refers to a character who travels with, or shares adventures with, the Doctor. A companion is generally the series' co-lead character alongside the Doctor for the duration of their tenure, and in most Doctor Who stories acts as an audience surrogate by providing the lens through which the viewer is introduced to the story, and often, the series itself.

The companion character often furthers the story by asking questions and getting into trouble; also by helping, rescuing, or challenging the Doctor. This designation is applied to a character by the show's producers and appears in the BBC's promotional material and off-screen fictional terminology. The Doctor also refers to the show's other leads as their "friends" or "assistants"; the British press have also used the latter term.

Fourteen actors have portrayed the Doctor in a leading role in the British science fiction television series Doctor Who. The series' protagonist, the Doctor is an alien from a species called Time Lords. The transition to each succeeding actor is explained within the narrative through the plot device of regeneration, which allows Time Lords a change of cellular structure when they near death, changing their appearance and personality. The first actor to portray the Doctor was William Hartnell beginning with An Unearthly Child (1963) through The Tenth Planet (1966). In the final moments of the serial, the First Doctor regenerated into Patrick Troughton's Second Doctor.

The most recent incarnation, the Fifteenth Doctor, was played by Ncuti Gatwa, who took over the role from David Tennant following the conclusion of "The Giggle" (2023). Gatwa departed the role in "The Reality War" (2025).

Sydney Cecil Newman (né Nudelman; April 1, 1917 – October 30, 1997) was a Canadian television producer and screenwriter who played a pioneering role in British television drama from the late 1950s to the late 1960s. After his return to Canada in 1970, he was appointed acting director of the Broadcast Programs Branch for the Canadian Radio and Television Commission (CRTC) and then head of the National Film Board of Canada (NFB). He also occupied senior positions at the Canadian Film Development Corporation and Canadian Broadcasting Corporation, and acted as an advisor to the Secretary of State.

During his time in Britain in the 1950s and 1960s, Newman worked first with ABC Weekend TV before moving across to the BBC in 1962, holding the role of Head of Drama with both organisations. During this phase of his career, he created the spy-fi series The Avengers and co-created the science-fiction series Doctor Who, as well as overseeing the production of groundbreaking social realist drama series such as Armchair Theatre and The Wednesday Play.
