The Doctor and Rose return to present day London where she finds that she hasn't been away for the 12 hours she thought had gone by, but 12 months. Her mother had been searching for her frantically, having filed a report with the police and putting posters with her photo on every lamp post. To their amazement, an alien spacecraft crashes in the Thames and Earth has it's first contact with extra-terrestrial beings. The Prime Minister has vanished however and those in charge are not what they seem to be. Working with the only Member of Parliament who seems to be in London, Rose and the Doctor battle a race of alien beings, the Slitheen, who want to destroy the Earth and sell if off, piece by piece.

Did You Know?


Originally, this episode featured the discovery of a buried "alien" spacecraft in a construction lot in Tottenham. It was only as production loomed that Davies began to realise what could be achieved with CGI, and so rewrote his scripts to provide greater scope for the introduction of the "alien", with the ship's destructive crashlanding now part of the narrative. Davies also elected to feature a live "alien" in the story, rather than just a corpse which would turn out to be nothing more than a shank of beef. See more »

[the TARDIS materializes on the Powell Estate, and the Doctor and Rose step out]
Rose Tyler: How long have I been gone?
The Doctor: Twelve hours.
[They both laugh]
Rose Tyler: Oooh! Right, I won't be long, I'm just gonna see my mum.
The Doctor: What're you going to tell her?
Rose Tyler: I don't know! I've been to the year 5 billion... and only been gone, what, 12 hours?
[the Doctor gives something between a laugh and a snort]
Rose Tyler: No, I'll just tell her I've spent the night at Shareen's. See you later!

"900 years of time and space..."
18 December 2008 | by (Italy) – See all my reviews

After handing The Unquiet Dead to Mark Gatiss, Russell T. Davies returns to write the first ever two-part episode of the new Doctor Who: London, an alien invasion and loads of humor.

The laughs come aplenty already in the teaser, when the Doctor arrives in London and tells Rose she can go home, since he set the TARDIS coordinates so that she was gone only twelve hours. Naturally, something went wrong, leading to our favorite Time Lord being accused by Jackie Tyler of kidnapping her daughter for a year. With the matter settled, a new inconvenience emerges: a spaceship has crash-landed in the Thames and the Prime Minister is mysteriously absent, which might have to do with the fact that his replacement is actually an alien in disguise.

Aliens of London works because it takes one of the original series' trademarks (something bad happening here and now, in broad daylight) and adapts it to 21st century paranoia and angst. It's sort of reminiscent of old stories like The Invasion (1968), which starred Patrick Troughton - the Second Doctor - and introduced the organization known as UNIT, which returns briefly in this episode (no interaction with the Doctor, though: Davies and BBC were adamant that no complicated references to the old mythology be made during the first season). Plus, it's funny as hell: when Rose finds out the Doctor (who got slapped by Jackie, by the way) is 900 years old, she remarks: "My mum was right. That is one hell of an age gap!".
