Daleks: Invasion Earth 2150 A.D. (1966)
“Rebels of London, leave your hiding places… soon we will destroy London completely and you will all die.”
We only see a van and a pylon crushed in the vicinity of Watford, but this rare feature-length outing for Dr. Who (starring Peter Cushing) takes place after the Daleks have flattened most of the city.
Luckily, Bill McGuffie’s jaunty jazz score stops things getting too sinister, while the Daleks make sure they leave Westminster Bridge in one piece – you think going up stairs is hard for them? Try crossing the river.
