  • Quotes (15)

    • The Doctor: (Looking up at helicopter) Take me to your leader!

    • (Dr. Sato and The Doctor are examining the pig-alien) Dr. Sato: I just assumed that’s what aliens looked like. But you’re saying it’s an ordinary pig. From Earth. The Doctor: More like a mermaid. Victorian showman used to draw the crowds by taking the skull of a cat, gluing it to a fish and calling it a mermaid. Now, someone’s taken a pig, opened up its brain, stuck bits on and they’ve strapped it in that ship, made it dive-bomb. It must have been terrified. They’ve taken this animal and turned it into a joke. Dr. Sato: So, it’s a fake. A pretend, like the mermaid. But the technology augmenting its brain… it’s like nothing on Earth. It’s alien. Aliens are faking aliens. Why would they do that? Doctor? (Dr. Sato turns round and the Doctor has disappeared)

    • Rose: When you say nine hundred years… The Doctor: That’s my age. Rose: You’re nine hundred years old? The Doctor: Yep. Rose: My mum was right. That is one hell of an age gap. (jumps down off the wall) Every conversation with you just goes mental. And there’s no-one else I can talk to. I’ve seen all that stuff up there, the size of it, and I can’t say a word. Aliens and spaceships and things… and I’m the only person on planet Earth that knows they exist. (At that moment, a large spaceship flies overhead, crashing into Big Ben and landing in the Thames)

    • Rose: And where do you think you're going? The Doctor: Nowhere. It's, uh, just a bit human in there for me. History just happened; they're talking about where you can buy dodgy top-up cards for half price. I'm off on a wander, that's all. Rose: Right. There's a spaceship on the Thames and you're just wandering. The Doctor: Nothing to do with me. It's not an invasion. That was a genuine crash landing. Angle of descent, colour of the smoke, everything. It was perfect. Rose: So? The Doctor: So maybe this is it. First contact. The day Mankind officially comes into contact with an alien race. I'm not interfering 'cause you got to handle this on your own. That's when the human race finally grows up. Just this morning you were all tiny and small and made of clay. Now you can expand.

    • Rose: I can't tell her, I can't even begin. She's never gonna forgive me. And I missed a year. Was it good? The Doctor: Middling. Rose: You're so useless.

    Trivia (15)

    • Albion Hospital, where the alien pig is taken, is the same hospital from "The Empty Child" and "The Doctor Dances".

    • When the Doctor and Dr. Sato are looking at the pig alien in the morgue, the "dead" pig's chest is rising and falling.

    • The Slitheen share some similarities with the Foamasi, an alien race featured in the Fourth Doctor serial The Leisure Hive; The Foamasi were also bulky green aliens who used skin suits to impersonate people.

    • This episode features the first appearance of Harriet Jones, here as MP for Flydale North. She eventually becomes Prime Minister, featuring and being mentioned in many later episodes.

    • When the Doctor is watching TV, we see the children's programme Blue Peter in which the host has made a U.F.O cake, that he has decorated with jelly babies. Although jelly babies are very popular in the UK, it's a nice nod to the classic series, since the 4th Doctor played by Tom Baker always had jelly babies in his pockets.

    • Rose: (After the Doctor asks who is the expert on aliens) Patrick Moore?

      Sir Patrick Moore, whom Rose suggests as an alien expert, is a famous British astronomer renowned for writing dozens of books on the subject which have made amateur astronomy accessible to everyone. Sir Patrick was born on 4 March 1923 in what was then the little Middlesex village of Pinner. At the age of six months he and his parents moved to Sussex where he has lived ever since - not counting the war years when he was a navigator in the RAF and a brief time in Northern Ireland in the 1960s. Between the ages of six and sixteen Patrick was ill, on and off, and this prevented him from attending school and so was mostly educated at home.
