Frequently Asked Questions
The most-asked questions about british television series about time travel.
What is the defining British time travel TV series?
Doctor Who, which first aired in 1963 and was revived in 2005, is the longest-running and most internationally recognised science-fiction show in British television history. It follows an alien called the Doctor who journeys through time and space aboard a ship known as the TARDIS.
Who is the Doctor and what is a Time Lord?
The Doctor is a member of the Time Lord race, an ancient alien civilisation from the planet Gallifrey that mastered the science of time travel. Each Doctor eventually undergoes 'regeneration,' transforming into a new physical body, which allows the role to be recast across decades.
What is the TARDIS?
The TARDIS stands for Time And Relative Dimension In Space and serves as the Doctor's time machine, home, and workshop. It is famously locked in the external shape of a 1960s British police call box, yet its interior is vastly larger than its exterior.
How many Doctors have appeared in the series to date?
As of the mid-2020s, fifteen actors have portrayed the Doctor across the classic run (1963–1989), the 2005 revival, and subsequent specials. David Tennant returned for a second stint as the Fourteenth Doctor in 2023, and Ncuti Gatwa took over as the Fifteenth.
Where should a newcomer start watching?
Most fans suggest beginning with the 2005 revival episodes starring Christopher Eccleston or David Tennant, as they establish the modern tone and format in an accessible way. For those wanting the original genesis, the 1963 pilot 'An Unearthly Child' is a natural entry point.
What is Torchwood and how does it connect to Doctor Who?
Torchwood is a spin-off series set in Cardiff, Wales, that follows a small team of agents dealing with alien threats and temporal anomalies. It shares the same fictional universe as Doctor Who and was created by Russell T Davies, who also revived the parent show.
Are there notable British time travel series outside the Doctor Who universe?
Yes—BBC's 'Time' (2021) follows two women who discover they can step into the past, and 'The Time Travellers' (2016) centres on a malfunctioning time machine in a small English town. H.G. Wells' 'The Time Machine' also received a 2013 BBC television adaptation.
What is 'regeneration' and why is it key to the show's longevity?
Regeneration is the in-universe process by which the Doctor's dying body transforms into a new one with a different appearance and personality. This narrative device has allowed the series to continue for over six decades by recasting the lead role without ever ending the story.
What are some of the most iconic moments in the show's history?
The TARDIS dematerialising at the close of the 1966 'Daleks' serial is often cited as the turning point that saved the series from cancellation. More recently, the 2013 'Day of the Doctor' special reunited three incarnations, and David Tennant's 2023 return as the Fourteenth Doctor generated enormous cultural attention.
Who are the key creative figures behind the modern era of the series?
Russell T Davies spearheaded the 2005 revival and wrote its early seasons, while Steven Moffat served as showrunner from 2010 to 2017. Chris Chibnall led the series from 2018 to 2022, and Russell T Davies returned as showrunner for the 2023 specials and the current run.
