The Dalek Invasion of Earth

Radiation nil, oxygen normal, pressure normal . . . an Earth reading! The TARDIS has landed in London. A menacing deserted London, with no sign of life and no sense of normality, but the decaying city is not as empty as it seems. The year is 2164 and the travelers soon find themselves facing antagonists whom they thought they had destroyed . . . the Daleks. They have conquered the Earth.

Ten years after a cosmic storm, continents of people were wiped out by a plague. Then the Daleks came in saucers, shipping humans to vast mining areas, turning them into robomen and against their fellow humans. Earth contains something no other planet contains--a magnetic core--but why are the Daleks digging for it and how can the Doctor prevent them from tampering with the forces of creation?

• The Daleks proved to be so popular from their first season appearance that they were brought back for a second adventure, this time on Earth.  Their return was capitalized early on in the second season.

• Susan, the Doctor's granddaughter, leaves at the end of this story, suffering the fate of many female companions to come after her...falling in love and staying behind to get married.  This is the first time that a companion had left the show.

• Apparently, in order to film the streets of London so they looked deserted, the production team had to go out and film on an early Sunday morning.

• "The Dalek Invasion of Earth" boasted quite a few lavish sets and special effects for that day and age.  Quite a bit of money was poured into the return of the Daleks.

• Due to the continuing popularity of the Daleks, this story was revamped a couple of years later for the big screen.  Peter Cushing played the Doctor in that story which played as a sequel to the first Dalek movie.

• If you can, you should really check out this story on DVD.  The story has undergone an amazing restoration process as well as having the DVD crammed full of nice extras.  Well worth a look.  :D
