The Krillitanes - aliens with a mix-and-match physiology - are trying to crack the 'God-Maker', a paradigm to give them ultimate power. They are using children as a computer, and only the Doctor and Rose, re-united with Sarah Jane Smith and K9 can prevent them from becoming masters of time and space.

Did You Know?


Several moments were trimmed or excised in editing. Banter between Kenny, Melissa, Luke and Faisal prior to the Doctor entering the classroom in the teaser - which would have fleshed out the children's characters - was cut. Later in the same scene, the Doctor's questions to Milo would have actually made him collapse, prompting the Doctor to bring him to the school nurse (another Krillitane); this was still alluded to in Wagner's dialogue with Melissa. The Krillitanes eating the hermetically-sealed rats was removed, and instead replaced by a voiceover explanation by the Doctor. Another voiceover was used to truncate the scene in which Kenny deduces that the fire alarm will disorientate the Krillitanes. See more »

Mr. Finch: [walking the halls while making fingerings with his left hand as if playing a three-keyed brass instrument, then sings softly] Bom bom bom bom / Da-bom bom bom.
Mr. Finch: [He walks just past Nina waiting in a chair by his Headmaster office, stops, and turns taking notice of her] What do you want?
Nina: The nurse sent me, sir. I was in English and I got a headache.
Mr. Finch: Then don't bother me, go home.
Nina: I can't.

Quite easily one of my top five favorite episodes (if not #1). A good story. Poignant moments, cheeky moments, this episode has it. A satisfying tribute to the Classic DW with one of the most popular companions from the classic era. You can see from the moment that the Doctor first sees Sarah, that this is going to be something special. And it delivers. The initial byplay, the scene in the café where Sarah believes she did something wrong, to complaining about the navigation of the TARDIS (You'd think that with all the time The Doctor spends in England, he and the TARDIS would know the difference between Aberdeen and Croydon). But the big highlight for me was the "discussion" between Rose and Sarah in the classroom. What starts out as open antagonism becomes a funny, wonderful scene where the 'old' generation eventually bonds with the new. And I can't help but smile at the fact that Sarah Jane gets the last word in ("The. Lock. Ness. Monster!") This episode also provided the inspiration and impetus for "The Sarah Jane Adventures".
