It was 2009. David Tennant was on his way out, and the BBC decided to celebrate by sending a double-decker bus through a wormhole into a desert. Honestly, at the time, Doctor Who Planet of the Dead felt like a bit of a breather. We had just come off the emotional devastation of "Journey’s End" and the snowy Victorian gloom of "The Next Doctor." We needed sunshine. We got it—literally. This was the first ever episode of the show filmed in High Definition, and they flew the entire crew to Dubai just to make sure the sand looked "real" enough.
People often dismiss this one as "the bus episode." That's a mistake.
The Bus, the Lady, and the Desert
Most fans remember Christina de Souza. Michelle Ryan, fresh off Bionic Woman, played the thrill-seeking cat burglar with a level of posh energy that actually rivaled the Doctor’s own eccentricity. Usually, the Doctor is the one dragging a confused human along for the ride. Here? Christina was already halfway out the door with a golden chalice before the Doctor even realized they were on a different planet. It was a weird dynamic. It worked.
The plot is deceptively simple. A London bus (the 200 to San Helios) gets sucked through a spatial hole and lands on a planet of infinite sand. It sounds like a bottle episode, but the stakes ramp up fast when they realize the sand isn't just sand—it’s the remains of a billion people.
Why the HD Jump Mattered
You have to remember how grainy the 2005-2008 era looked. It had that cozy, standard-definition fuzz. When Doctor Who Planet of the Dead aired, the visual shift was jarring in the best way possible. Director James Strong took full advantage of the desert light. You could see the sweat. You could see the individual grains of sand on Tennant's coat. It made the threat of the Tritovores—those giant fly-headed aliens—feel far more visceral and less like "guys in rubber suits."
Actually, the Tritovores are a great example of Russell T Davies’ writing style. They weren't evil. They were just... there. They were salvagers whose ship crashed. In a lesser show, the fly-people would be the monsters. In this special, the real monsters were the Stingrays. These giant, metallic, flying rays were literally eating the dimension. They don't have a plan. They don't have a monologue. They’re just cosmic locusts. That's terrifying.

The Prophecy That Changed Everything
If you ask a casual fan what happened in this episode, they’ll mention the bus flying. If you ask a die-hard Whovian, they’ll mention Carmen.
Carmen, played by the late Odette Khan, was the "psychic" passenger on the bus. Most of the episode, she’s just providing flavor text, but the ending hits like a freight train. She tells the Doctor: "Your song is ending, sir. It is returning, it is returning through the dark. And then, doctor... he will knock four times."
This wasn't just a spooky line. It was the beginning of the end for the Tenth Doctor. It turned a fun, breezy Easter special into a countdown to a funeral. Every time Tennant smiled for the rest of the episode, you knew he was thinking about those four knocks.
Production Chaos in Dubai
The filming of Doctor Who Planet of the Dead was a nightmare behind the scenes. They shipped a 1980 London Bristol VRT bus to the Dubai desert. Then, a crane dropped a container on it. The bus was literally smashed. The production team had to scramble to write the damage into the script, claiming the bus was "scuffed" coming through the wormhole. It’s one of those happy accidents that makes the episode feel more grounded. If the bus had arrived in pristine condition, it wouldn't have felt right.
Malcolm and the UNIT Connection
We also have to talk about Lee Evans as Malcolm Taylor. He was the quintessential Doctor Who fanboy character before that became a tired trope. Malcolm was the UNIT scientist stuck back on Earth, obsessed with the Doctor, and refusing to let his "bosses" shut down the wormhole.

His chemistry with the Doctor—despite them being in two different dimensions for 90% of the runtime—is incredible. It gave us a glimpse into how the world sees the Doctor: as a legend, a myth, and a bit of a hero to the nerds in the labs. It grounded the "space magic" of the Stingrays in real-world physics. Well, "Doctor Who physics," which basically means talking fast and pressing buttons.
Is It Actually Any Good?
Critics at the time were split. The Guardian called it "a bit of a romp," which is British code for "fun but shallow." But looking back, it holds up better than many of the more "serious" specials. It’s a masterclass in pacing. We start with a heist, move to a survival horror in the desert, and end with a high-stakes flight back to London.
The episode also deals with the Doctor’s loneliness. He refuses to take Christina with him at the end. Not because she isn't capable—she’s arguably one of the most capable people he’s ever met—but because he knows he’s dying. He’s already seen the end. He’s protecting her from himself. That's the nuance Tennant brought to the role that often gets overshadowed by the "Allons-y" shouting.
What You Should Watch Next
If you’ve revisited Doctor Who Planet of the Dead recently, you’ve probably noticed how much it sets up the "Time Lord Victorious" arc. The Doctor is starting to get arrogant. He’s starting to think he can bypass the rules of the universe.
To get the full picture of this era, you really need to follow the thread:
✨ Don't miss: Dark Reign Fantastic Four: Why This Weirdly Political Comic Still Holds Up
- The Waters of Mars: This is where the Doctor finally snaps and decides he’s the boss of time. It’s dark, claustrophobic, and the direct thematic sequel to the "fun" of the desert.
- The End of Time (Parts 1 & 2): This is where Carmen’s prophecy finally comes true. You’ll see the "four knocks," and you’ll see why the Doctor was so scared of them in the first place.
- The Power of the Doctor: For a more modern perspective on how the show handles these massive, world-ending threats with returning characters, this Jodie Whittaker finale echoes some of the "spectacle" vibes first pioneered in the 2009 specials.
The best way to appreciate the Tenth Doctor's exit is to realize it wasn't just one episode. It was a slow-motion car crash that started under the bright sun of San Helios. Don't skip the "bus episode." It’s the last time we see this version of the Doctor truly having a blast before the shadows catch up to him.
Go back and look at the scene where the bus finally flies. It's ridiculous. It's campy. It's exactly what Doctor Who should be. But keep your ears open for that prophecy. That's where the real story lives.
Check out the official BBC Doctor Who archives or the physical Blu-ray releases for the "Doctor Who Confidential" episode covering this shoot. The footage of them trying to fix a crushed bus in 100-degree heat is almost as entertaining as the episode itself. It gives you a real appreciation for the "Special" era of the show, where the ambition often exceeded the budget, but never the heart.
Practical Next Steps for Fans:
- Audit the Prophecy: Re-watch the final five minutes of the episode and pay close attention to the Doctor's facial expression when Carmen speaks. It recontextualizes his entire performance in the following three specials.
- Compare the HD: If you have the old DVD and the Blu-ray, compare the desert scenes. The 2009 HD transition was a landmark moment for British television production that paved the way for the cinematic look of the Steven Moffat era.
- Explore the "Missing" Companions: Research why Michelle Ryan didn't return as a full-time companion; there were several rumors about her joining the TARDIS permanently that never materialized, making her one of the Great "What Ifs" of the show's history.
