This entertaining sequel to 1965's Dr. Who and the Daleks has been released under several titles: Invasion Earth 2150 AD, Daleks Invade Earth: 2150 AD, and Daleks-Invasion Earth 2150 AD. So guess when the story takes place? Peter Cushing returns as eccentric time-traveller Dr. Who, idol of millions of BBC viewers and PBS pledge drive fans. This time, Dr. Who, his niece Susan (Roberta Tovey) and a flustered London bobby (Bernard Cribbins) are whisked into the future via the Doc's TARDIS call box. In 2150, London is under siege from the extraterrestrial Daleks, with whom Dr. Who has crossed swords in the past. The Daleks intend to convert the earth into a huge spaceship by activating the planet's metallic core. Props essential to the action include flying saucers, death rays and robots, all of which look a lot more expensive than those silver-painted tinker toys seen on the Dr. Who TV series. Coproducer Milton Subotsky based his screenplay upon a Dr. Who television continuity written by Terry Nation.
