The one thing the Doctor always keeps near is the Tardis. So losing it in a black hole somewhere in deep space is a bit of a worry. Not least, he says, because without it he'll have to settle down and get a mortgage. In this two-parter (The Impossible Planet and next week's The Satan Pit), the Doctor and Rose land in a ramshackle spaceship stationed on an obscure planet that's trapped in permanent orbit round an all-consuming black hole. But that's only half the problem. An army of hideous-looking Oods stalks the corridors, while a disembodied voice repeats, "The beast is awakening." Written by Jane Rackham

Did You Know?


The voice of the Beast is provided by Gabriel Woolf, who also played Sutekh the Destroyer in the Fourth Doctor serial Pyramids of Mars (1975). One of the names that the possessed Ood have for the Beast is Satan. The Fourth Doctor also stated that Sutekh has been known by many aliases, including the Typhonian beast and Satan. See more »


The Doctor insists that it's impossible to orbit a black hole. Black holes are like any other body. They can be safely orbited as long as you're far enough away or going fast enough. Close to a black hole, the orbital velocity becomes faster than light. But there's no mention that they are that close, within the event horizon. See more »

The Doctor: I don't know what's wrong with her. She's sort of queasy. Indigestion, like she didn't want to land.
Rose: [straight-faced] Oh, if you think there's gonna be trouble, we could always go back inside, and go somewhere else...
[Rose cracks up, and they laugh outrageously]

How very Ood
20 January 2007 | by (United States) – See all my reviews

Rose and the good Doctor find themselves in a space station that is on a planet that's quite impossibly hovering in orbit right below a black hole. The crew of the station is just as perplexed at that as the two new inhabitants are. Suitably spooky in it's atmosphere and gets better as the Doctor and Rose find themselves stranded due to circumstances out of their control and speaking through the submissive alien race of the Ood, something quite dark is coming from below the crust of the planet. Not haven seen the second part of this two-parter I can't vouch that the end is as strong yet. But it does make for one hell of a beginning.
