Continuing their quest for the Key to Time, the Doctor, Romana and K-9 travel to the cold planet Calufrax, but the TARDIS lands somewhere else instead - right time, right place, but wrong planet. It's a curious world ruled with an iron fist (somewhat literally) by the cybernetic space pirate known as The Captain and littered with the rarest gemstones in the galaxy. As the Doctor tries to get an accurate sense of the place (and find Calufrax), one of the planet's younger citizens, suffering nightmares of a sort, becomes the target of a group of monk-like telepaths.

Did You Know?


The name "Bantraginus V" is likely a reference to "Santraginus V", the home for one of the key ingredients in the Pan Galactic Gargle Blaster in Douglas Adams' The Hitchhiker's Guide to the Galaxy. See more »


Some handwritten notes can be seen after the Doctor rips a page out of the manual. Mary Tamm (playing Romana) hides the page from the camera after a few seconds. See more »


The Doctor: Well, according to these space-time coordinates, we have arrived at precisely the right point in space at precisely the right time.
Romana: Yes, I know.
The Doctor: But to the wrong planet.
Romana: What?
The Doctor: This isn't Calufrax.
Romana: Then where are we?
The Doctor: I haven't got the faintest idea.

it's Douglas Adams, how can you NOT see it?
4 June 2008 | by Quinoa1984See all my reviews

If you're any stretch at all of a fan of Douglas Adams or his Hitchhiker's Guide to the Galaxy, you're either already a fan of Dr. Who or may come across this episode at some point or another. It's actually a great place to start for a (relative) newcomer to the original series, as the story gives a strong combination of the humor, camp, pathos and excitement that Doctor Who provides at its finest. So hopefully this is the "some point".

As someone who's only seen two or three episodes of Dr. Who- both 'old' and 'new'- this is top of the crop. Adams gets how to make it an interesting mystery for the good Doctor Tom Baker to figure out the problem of Calufrax with the section of the key of time they need. It's got some hilarious moments and lines of dialog that are quintessential Adams ("Plank. Theory: simple. Walk along it. Come to edge. Fall off 1000 feet. Die!"), and some cool looking creatures, and of course the Captain, who kicks ass as a dastardly Dr. Who villain.

Must, must see, all four parts of course.
