Twenty Years Ago, the Longest-Running Sci-Fi Series Perfected a Captivating Trope

(SeaPRwire) –   When Doctor Who debuted in 1963, it was originally conceived as an educational history series, featuring the Doctor traveling through time to interact with historical figures—hence why the first companions were teachers. Though audiences gravitated more toward the science fiction elements, Doctor Who never abandoned its historical roots, including storylines involving Winston Churchill, Queen Victoria, William Shakespeare, and Richard Nixon.

Twenty years ago, one such historical episode unfolded a poignant cross-century love story. At the time, it stood out as a visually stunning standalone episode with lasting impact. Yet, in hindsight, it marked the beginning of a significant shift in tone for the entire show.

Set across two vastly different eras, “The Girl in the Fireplace” follows Reinette (Sophia Myles), also known as Madame du Pompadour, who witnesses the Doctor appearing through mysterious portals in her fireplace throughout 18th-century France. In contrast, the Doctor (David Tennant), Rose (Billie Piper), and Mickey (Noel Clarke) encounter a completely deserted spaceship in the 51st century. However, appearances are deceiving: in France, Reinette is being terrorized by unsettling clockwork drones masked in porcelain, while aboard the ship, advanced technology has been replaced with human body parts.

For the Doctor, these events occur within a single day, but for Reinette, he remains a constant presence throughout her lifetime—never aging or changing. He becomes her imaginary companion, making her involvement in the unfolding mystery all the more emotionally charged. In the climactic moments, the Doctor promises he’ll return soon, unaware that by then, it will already be too late for Reinette. The episode culminates in a twist reminiscent of The Twilight Zone, revealing that the clockwork droids had been protecting Reinette because the spaceship they served was named after her—and they simply misunderstood their mission.

This adventure was penned by Steven Moffat, who had previously crafted the acclaimed two-part story “The Empty Child/The Doctor Dances” during Season 1. The episode is rich with references, including the Clockwork Droids echoing the infamous Mechanical Turk automaton hoax, and notably, the central romance draws inspiration from the novel The Time Traveler’s Wife.

The “time-crossed lovers” motif would become a hallmark of Moffat’s writing throughout his tenure on Doctor Who. As a writer, he later introduced River Song in “Silence in the Library,” his wife who traveled through time in a non-linear fashion and became a major character. As showrunner, he explored similar themes in “The Eleventh Hour,” where Amy Pond meets the Doctor and is told he’ll return—only for years to pass, transforming him into her imaginary friend—and in “The Big Bang,” where Amy’s husband, Rory, endures 2,000 years of waiting to safeguard her inside the Pandorica. In a full-circle moment, Moffat even adapted The Time Traveler’s Wife into its own miniseries.

This fascination with love fractured by the constraints of time now defines much of Moffat’s work. “People always used to ask me, ‘Why do you do out-of-sequence storytelling?’” Moffat told Inverse in 2022. “And I’d always say to them, is your memory in the right order? When you think about yourself, do you go from being born to being 1 year old to 2 years old? No, it’s a chaotic jumble. You wouldn’t even know what the order was.”

That enduring obsession with love torn apart by having to take “the slower way” can all be traced back to this episode. While there are more tangible legacies—such as the Clockwork Droids reappearing in the Season 8 premiere “Deep Breath”—“The Girl in the Fireplace” truly represented a turning point in Doctor Who, transforming the series’ approach to time travel from educational to speculative science fiction, and nearly romantic.

Doctor Who (2005-2022) is available to rent on Prime Video, Apple TV, and other platforms.
